Hot and cold water pipes

[Bernard]

My bathroom job... What can I do about the hot and cold water pipes that run from the floor boards up the wall and are meant to attach to the sink? (Which has been removed). They only start touching the wall about half way down and I could tile to this point if I gently bend them away but at about 8 inches from the floor they're on the wall with no moving them.

Cheers.

I guess your only option is to access them below the floor level and renew them to suit.

If removing and replacing the pipes from below the floor isn't an option then tile upto the pipes and I'd silicone the cuts to seal them.

If (as suggested) there is any way you can pull up the floorboards then I would personally cut the pipes back until they were under the floor.

I would chase out the plaster to just under the sink. Then embed polyplumb plastic pipe into the wall under the floorboards and reconnect.



Messy - yes - but by chasing out the wall behind you get a great finish



I hate exposed pipes with a vengence!

If your sink has a half pedestal then it will hide the entry points for the pipes



Much nicer not to see any pipework.!

If your sink is exposed you can drill neat holes into the tiles and bring through chrome pipes from the wall

Explain to customer the benefit of chasing the wall to give better finish a few quid in your pocket and a happy customer were all winners

If you cant redo them from under floor level, or chase them into the wall, tile upto them and either box them in or cover them with a trunking or pipe snap covers.

cut the pipes under the floor and alter to suit,failing that,2 other options,
1,box pipes in
2,fix tiles around the pipes,obviously keeping to your lines

Sorry to resurrect an old thread but the photos here are just what I want to do. I need to run pipes to a rad and a feed to the loo along a wall, my thought was to chase the wall out (like the photo) and (using) speedfit plastic pipe/connections run the feeds through the wall. I would end up with 3 elbows within the wall (one on each pipe to exit from the wall)

I'm wondering how the gap that's chased is filled? Do you just ply over it to keep the cavity?
I would also be concerned about having joints in the wall, but presumably you could leave the gap where the joint is and try and tile straight over? Worst comes to worst you would be able to hook out a few tiles and gain access.

Any thoughts?

Usualy a bit of bonding plaster to fill the gaps where the pipes are.

Dont worry too much about whats going on behind the tiles. You can rough kango the wall to chase in the pipework.

Once you tile over then you will never know whats behind. Pipes can "knock" if not secure so make some effort to tie them.

As long as your exit pipes look neat on the tiles then you wont have too much to worry about.

Example:



Shown is a 32mm sink waste (socket used 40mm) and a 15mm copper pipe for the hot and cold (socket used 16mm)


However if you are coming through with polyplumb fixings then a 30mm hole will give you clearance if you want to be sure of getting the fittings through.



Here you can see in more detail that we cut a 30mm hole for a polyplumb joint



If your "tail" is going to be the 15mm pipe (copper or plastic) then go for the 16mm hole
If its likely one of the fitting will be in the hole then 30mm is your size.



15mm hole

(make sense? )

Thats very informative, thank you. I have decided not to chase into the wall but will instead use chrome pipe as its only a short run. I will however have to bring myself some tails out for the shower so your post is very helpful, thank you.

You will need to file off the chrome if you are using push fit fittings as the grab rings wint grab the shiney chrome surface!

I have decided not to chase into the wall

No problem just make sure you dont regret anything later on.

Preperation is the key and sometimes a bit of mess now can reap rewards with the finish later...


Radiator pipes chased into the walls

But its your project! - We just give general advice on here.

Hmm that does look good! I'm in two minds! Will see how I feel about it when I get back there today. Might change my mind again!

You can get those chrome elbows pictured with a ballofix isolator built into them too. These remove the need for a seperate one if you need to have one
