Plumbing Underneath Your Kitchen Sink – Plumbing Tips

– Hi guys, if you’ve been
lucky enough to stumble across this lovely video all about how to fit the
pipework under your kitchen sink, then great, we’re gonna get down to the video any minute now. First things first, I’m
gonna put my phone on silent. Secondly, do yourselves a favour

sure that your notifications are switched on. Then, when we upload a
new video, you’ll get one little notification just
telling you that it’s happened. Anyway, hope you enjoy this video, guys. And remember, hold tight., home
of Find Your Plumber. Boys and girls, so here is
the beast we have in question. We’ve got a little funky sink here. We’re going to be putting a hot and cold and also a feed to a fridge
that’s just out of shot, up into the back of this unit here, and we’re going to show you how to. These jobs aren’t going
to be completely relevant to everything you’re doing because every job’s completely different. But it hopefully is going
to give you a bit of an idea about how to do this sort of job neatly and also to make it so once you’ve gone, especially as a plumber, the homeowner can turn all their stuff off or if you are a homeowner and
you’re trying to figure out how to do this ‘self, the
importance of adding valves. That’s what we’re gonna
do, let’s get going. So, quick look around this job. Down here we have got this
horrible load of pipework here. We’ve also got the cold coming in here, in a lovely little bit of
a pipe there, very nice. What we’re gonna do is
turn off the water supply, we’re gonna get these pipes
so they actually fed up into the back of here. And then we’ve got a dishwasher
and a washer machine, either side just like so, but really it doesn’t
really matter which way they are around because
they have the same complete facilities when it comes to feeding. So number one on my particular job sheet is to find a piece of paper
and actually sketch out on here what I’m going to do. It’s almost like I’m
going to have a pipe going up there to there, there to
there, and there to there. Just draw it out. And then what you’re
going to be able to do is know exactly what fittings you need. Because the work top isn’t in here yet, the customer temporarily wants us just to put a tap on here like so. So for demonstration purposes, it’s gonna give you a pretty good idea about how to pipe the tap up, as well. I actually love doing this sort of job, because it’s designing from scratch. “A thing of beauty is a joy forever”. So, I’m just going to have
a little scribble down now, and see exactly what we want. We are just under here like
that, and as you can see, we’ve got our waste coming in, we’ve got the cold
water out to the fridge, cold water main to the system, the hot and the cold water main in. And what I usually do is
actually we’ll go up here, and as you can see, I just
drill these holes here. I’ve just marked up these holes where I want to drill them. So what I’m going to do now,
right away, is guess what, drill those holes first. (drilling) Right, so there we go. We’ve got our holes drilled in, and as you can see from down here, we’ve got our cold water main coming in, we’ve got our hot water coming in, our cold water off to the system, and then also the cold water that goes to the fridge, as well. So, what I’m going to do is I know that my hot is
basically going to come up into this corner and just sit out of the way. What I’m going to do is add
a little bit of pipe length to that so when they put
the actual worktop on when this job’s finished,
we’ve got enough slack to take that up and they
just have to remove the tap and then put it back on again. And we’ll do the same with the
cold, as well, in a minute. So, what we’re going to do,
is because this is gonna be where our hot comes up. Let’s get my spirit level, and then we’re just gonna
draw a line up there and do the same here with the cold. Depending on how good my hole drilling is, this should be roughly
the same sort of distance. And that along there and
then we’re just going to pop clip, clip, clip, clip there. Right, and because I know
roughly where my hot is, what we’re going to do, is
I know that I can measure up from just under here. So, just go on here,
add 18 mil or whatever. I know I’m going to be pretty safe. I’m going to bring this up right high, actually instead I’m just gonna run my, I’m just gonna put basically
a bend on here, like so, and then over to where our hot is. Really pleased actually that
we’ve got this job to film. It’s really, really handy, because you can’t get a really good idea, a really good view of
everything that’s going in. So, that’s going to give
us loads of slack there on that hot. Actually, we’re going to
pop a little valve on here. And also, just have a box
of clips sitting next to you the whole time you’re doing this. And also, a little straight, as well, your little straight head, because you want to
make this look gorgeous. Right, so now, we really need
to put our cold main coming up here with our cold main
stopcock, as well, on there. (squeaking) Oh, that squeak. So now, when they squeak, they leak. That’s something I can tell you. What we’re going to do,
I’m gonna put a bend on this actually quickly, as well, because we’re going to sweep over. We’ve got basically three
valves coming off all together. One for the fridge,
one for the dishwasher, and one for the washer machine. So now, this is up to you to go right, how are we gonna make this beautiful? Number one the things
that concern me the most, when I’m installing this
sort of system is this: everything should be at
the back, out of the way, so if anyone wants to use the cupboard, they have the space to be able to do it. But also, everything needs
to be easily undo-able, so if you need to come back
or tighten something up, then that’s great. And also everything needs
to be easily accessible for people to turn stuff off. You don’t want someone
with water going everywhere going absolutely mental
because they can’t turn it off. They are the things that I worry about. So, for this particular
part, you need a few teeth, a few elbows, and your brain. Think to yourself, “Am I going
to be the one living here, “am I going to be the one coming
down at two in the morning “needing to turn
something off real quick?” If you are, then do it like
this, because it’s the best way. Well, where was I? (laughs) Right, so the reason I’m
putting in a little cold valve on here as well, to the system out is because if there’s a
problem with the cold system somewhere else in the house,
they can isolate it just here, and still have water up to
the sink so they can still use the washer machine, stuff like that. They’re not completely
stuck, that’s all it is. Thing as well, if you get the
opportunity, or a decent idea just to nip up anything
you got to nip up, now. Right, and now comes the
bit that is difficult because as you probably can see, we’ve got a little bit of an overlap here. We’re gonna have to bring our cold up and it’s gonna have to come over the top of that hot and do that. Really, really simple thing
to get over if you know how and what you’re doing. So, what we’re gonna do
is we are going to bend three bends exactly the same. So, little 45 probably, nothing crazy. So, I tell a lie, we’re
going to bend two bends of that size. This isn’t the crazy way that you all have to do it every time. Push-pin to there actually. Loosen that, we have the same
thing to do here, as well, just another little one. You’ve guessed it already,
you probably guessed it. We’re just gonna join the
top of that up just like so. Actually what I could do there,
is I could make that one a T and that could be our spigot. (light jazz music) (slight shuffling) Right, like I said this
is kind of temporary what we’re doing here at the moment. So, what we need to do
really, this is so simple, we’re gonna be popping a hole
up through here for the waste. And as you can see,
we’ve got our two waste ready for the dishwasher and
the washer machine as well. So they are ready to go, nice and easy. Swing it around there. I know where the waste centre is, because I’ve marked it up on here. So all I need to do is get my drill, drill a biggish hole around there, and then we can get our waste installed. (drilling) Right, 45s are the way to go if you can. If you can’t, then fitting
90s are perfectly fine, but I prefer 45s if you can, because you do get a little
bit of a better flow. (light jazz music) So boom, there we go, all done. I mean, obviously, this is
all that’s gonna be taken out pretty soon when they
put this new work top on. I’ve mentioned that a few times already. But hopefully this should all be alright. I hope you love the way
that we’ve kept everything as far back as we possibly can. We’ve obviously got our
washer machine and dishwasher connectors all there,
as well, ready to go in. I’m gonna wait for the
chippy to come along and just cut their holes for that because we don’t actually
know quite straightaway what they’re gonna be doing. So it’s probably best, just
to leave ’em to do that. And also, times gettin’ on,
it’s nearly five o’clock. I need to go home, (laughs)
I’m only jokin’, don’t worry. We’ll just whack these here,
I’m just gonna wait for them to come along then we’ll do it there. Anyway, I know this video
hasn’t been 100% me telling you exactly how to do
something the whole time, but I hope that it’s given
you a better idea about, taking the time to design
some of this stuff and make it so it looks nice when it goes to the back. So that you could still use the cupboard, but also making sure that all
the valves are easy to get at, as you can see, we can
get to all those valves really easily there. Any problems, that’s great. So if you just wanna know, you’ve got the cold coming up here, obviously then our cold feeds
off out down to the fridge, cold feed off to the house. So now if they’ve got
a problem with a leak somewhere in the house,
bang, they can turn that off and they can still use the sink without having to worry
about the rest of the house. Basically, it doesn’t get
much better than that. Anyway, I hope you’ve

  1. Hope you enjoy guys! Just a quick video to show you what I think is important when you're installing under a kitchen sink….we all have our own ways. Tell me yours! PP!

  2. Nice and neat. Aren't the trap connections going to be slightly short unless the worktop is the same thickness as the mdf. Not knocking your work, just wondering?

  3. Just bought a house that needs totally replumbing. I hope my plumber can do half as nice a job as this! I'd do it myself but the missus won't let me! Says I'd take too long.

  4. Nice and neat, exactly how it should be done with a little forethought and insight turns it into a job well done and not a spider mess!

  5. Beautiful, I do love ogling at a nice bit of under sink plumbing! Ooer one of the first skills we were taught at plumbing school was straight pipes through pipe clips!

  6. Hey I'm a 3rd year aprentice and I was just wondering do you have any tips for soldering when the two fittings are literally side by side. I normally double 45 it to make room. Also do you have any tips for soldering the bottom part of a fitting I always seem to get a bit of solder dribble. Thanks for the videos ๐Ÿ™‚

  7. Brilliant video! great pipe work, really like the design stuff. I just plumbed the sink in our bathroom, just a simple hot/cold/waste setup but I'm chuffed with it ๐Ÿ™‚

  8. im not sure what code is in the UK but in canada the trap you installed would basically be called an "S" trap. here we need the venting to be above the trap not below. Do you ever find that the ptrap self siphons on that particular set up?


  9. Man this video demonstrated plumbing from last century…. You really should go to Finland or germany to learn the new way of plumbing. It seems you love soldering so much you dont care about firehazard precautions….

  10. Nice neat job. The only thing is (here he goes!!) I always chuck the waste kit away and fit two seperate p traps. I do this because the trap is there to create a seal and stop the drain odour coming back up through the waste pipes. With the waste kit, there is a reasonable amount of pipework before the water seal and I've found this can eventually lead to waste build up in that section of pipework and odour escaping into the kitchen.

  11. Fantastic vid mate. Doing a kitchen mixer tap for a friend on monday and this has given me the confidence i need.

  12. Wanna see more pics like. That plumbing porn from. That plumbing disasters video where it was all copper beneath the sink!! Soo satisfying

  13. #Deniz_92 Can you turn off the vignetting filter please? Its a but distracting! ๐Ÿ™‚ @Luke Smalley

  14. Is there any chance you could go at a steadier pace for us beginners to see what you really do or is that a trade secret?!

  15. i am a senior never did this before but empty pockets means this is a diy job.too much talking.not enough actual explanation when the older copper pipes have white plastic ends?? how to connect the new metal fittings to the older copper pipes.the job is completed without seeing how the stopcock tap is installed,could not see the most important.cheerful chap but i need to see more detailed step by step especially removing the d/washer connection and replacing it all with new.a lot od info on tidiness not enough on connection

  16. Watching this on my laptop. Recording is far too low. If I was on a train or something there would be no chance.

  17. Another very helpful video James. Thanks! Question: Would you recommend doing all that plumbing with plastic pipes and push fits?

  18. Nicely explained dude. Worth noting that not all base units have backs thick enough to fix pipework to though. I prefer to have pipes coming in from the back to prevent losing anything down holes in the base of the cabinet….

  19. Just a quick question regarding the washing machine drainage. I notice that the drainage pipe that the washing machine drainage hose is going to be connected to is practically horizontal to the drainage pipe for the sink. Does this mean that when the sink is emptied suddenly and all the water rushes away that some of it will go up that left hand drainage pipe and down the washing machine drainage hose into the washing machine just from the force of the water rushing down from the sink hole if you get what I mean.

  20. Is syphoning not an issue with your plumbing codes over there? S traps like that have been totally banned in North America. Either you would need an air admittance valve, or an โ€œislandโ€ vent installed.

  21. I have recently come across your pages and subscribe straight away you are a credit to all plumbers out there a true craftsman of his profession love watching your videos and most importantly learning from yourself top man ๐Ÿ‘๐Ÿป

  22. thanks for the video, my diswasher is about 1.5m away from the sink how should i run the waste to the sink across and also the cold , thanks

  23. Wow, what an aesthetically pleasing job, which is what's important to me and in my opinion makes all the difference when working in the houses of others, love it! Thank you

  24. I've had a wire spider down my sink, chemicals and caustic soda but its still completely blocked after three weeks. Got the trap off and its all clean. Now ive no boiler, no washing machine and no sink and dont know what to do. Any ideas please?

  25. Please consider subscribing – Uploading still today!

  26. Im adding the washing machine plumbing under the sink do i need to add the washer connection valve to the cold feed or the main feed we have 3 pipes under the sink hot cold and main ?

  27. It is very unusual but this isnโ€™t the way none of the other videos, diagrams and websites use. Please explain why each thing why so itโ€™s clearer.

  28. If you'd put the cold feed on the rhs, you could have avoided the bend to come over the hot pipe… but very neat and tidy, like how you kept it all at the back.

  29. If thatโ€™s the incoming main shouldnโ€™t you have a double check valve above the stop cock and a drain off is good practise. Looks lovely though

  30. Nice vid! Id like you working on my house.

    Would have been good to summarise what youd done with the copper pipes – didnt really follow what youd done
