Nightmare Job

[jaydebruyne]

I've been given a bit a nightmare job for tomorrow..

Some pipework underneath wooden flooring is leaking. The pipework has been exposed and leak sourced.

But the pipe needing repairing (15mm) is underneath other pipework (22mm).

Basically, my questions are these:

What is the best way of repairing a section of rigid pipework? There is no give whatsoever and it will be under flooring so will need soldering.

Basically i need to chop off some 22mm pipe to get to the 15mm and re-solder an elbow.

Try get a slip coupling in the mix, you get them in solder

Didnt know they did solder slip couplings ... Cheers ne1ls0n

Without seeing it, I would cut out say 300mm of the 22mm pipe, then the damaged section of the 15
Use two 15 slip couplers (or standard straights and use a round file to take out the indents or stops) fitting them fully onto the new piece of pipe, drop into place then slide back onto existing pipe
Then do the same with the 22

Or if its just small a nail hole, cut through the pipe where it is pierced and just use one coupler

If I had 300mm to play with it wouldn't be a nightmare job lol
I'll have to take a pic tomorrow and post it.. I think I have about 150mm to play with, if that...

Its leaking from an elbow joint.. But its in such a position I cant get at it with a torch

 

[ShaunCorbs]

as above slip coupling but use a stnd coupling with the stop to mark when the coupling ends, you can make a stnd coupling work takes less than 5 mins with the good old file

 

[jonnyswamp]

Can you prefab a 90 bend with a bit of pipe in each side, then use the slip couplers
Or, can you get hold of a preformed 90 bend (the type that come with some boilers for the iso's) and do the same
Can't picture what you're doing, so may be talking rubbish

Gonna file a few down now and see if I can sort it for tomorrow... Beats paying £2 a fitting

Bring down the ceiling

Luckily, its a ground floor flat

I honestly wouldn't be attempting a solder repair in that tight space mate

takes a bit longer with compression couplings, so get the lathe out

Really? Even though its under the floor? You'd use compression?

whats below earth concrete etc?

Yeah but the leak caused the wooden flooring to bow.. Its not the beneath I'm bothered about too much..

can you get your slice on the 15mm pipework and as-long as there no timber below eg encase your flame touches it you will be fine

I can barely gat my finger around it so don't think a slice will go over it. I wish I took a photo before as it would be easier to come up with a plan... I'll just have to wing it.

Just made my first 2 slip couplings so fingers crossed it all goes to plan lol either that or I explain how the new water feature works to the tenant

well you can try and sprinkle system to combat the gas rouges

 

[jonnyswamp]

draw a picture and post it

There's plenty of compression joints below the floor, no reason a well done up one would leak... Probes better than a speedy under the floor!

Dig out better access.

Make sure tenant isnt there whilst doing it either, the air will be blue. Oh and dont forget the elecfrical tape to wrap round your knuckles when you skin them.

Unfortunately the tenant is there and the hols is in the lounge where more than likely they'll sit and watch me sweat!!!

 

[SimonG]

Unlucky.

Just steady and methodical. Its character building

Haha that's EXACTLY what I need...

Someone told me that when I went to change steel pipe valves on 4 rads on a communal heating system... I looked at him like this:

The other one many moons ago was, its an adventure. Aye, righty o.

Its just one of those jobs. Dont forget to take some 3/4" fittings just incase the 22mm isnt.

if i remember right 20mm alk olives work

Incase the 22mm isn't what Mr G??

 

[ShaunCorbs]

incase its not 22mm and its 3/4

 

[jaydebruyne]

incase its not 22mm and its 3/4

Oh right... I'll grab some from plumbcentre in the morning

 

[jaydebruyne]

incase its not 22mm and its 3/4

Actually I'm pretty sure it's 22mm as a colleague went the before me and soldered another piece of pipe
