Soil pipe connections (replacing old)

[Nige1B]

Hi all,

hope you can help!

I'm updating my bathroom and having broken through a wall that I'm replacing have found a small drip I didn't know I had (see pic point 1).

Looks like the previous owner temp fixed by putting a load of solvent over the top of the joint. It's so small that it probably would never have been noticed.

As well as replacing this section, I want to do a proper job and put a new 90 degree connector into the branch on the soil stack.

My questions though are:

1. The branch into the soil stack looks like it is a push fit...as it's going to be quite an old piece is it risky to trust the seal as it already looks like it isn't perfect (point 2 on the pic) with 'browning' around the connection.

2. If the seal on the branch connection is no good, how do I fit pipe to it (I don't want to have to replace the branch in the stack). Is there a solvent weld solution as this will be fairly inaccessible once I box back in?

Thanks for any advice.

Cheers,

Nige

PS apologies if any of the terminology inst quite right...I hope you can understand what I'm on about.

Looking at your pic, are you sure that the pipe is going INSIDE the bend and not glued to it's outside? If it's going into a ring seal socket, most likelyit either doesn't have full slip past the O ring or the end of the pipe hasn't been chamfered properly and it's dislodged the O ring.

If I was doing it, I'd remove the bend and the section of pipe going into it and renew it back to the branch. I know its more work, but at least you'll get peace of mind that it's been done correctly.

Remove pipe and check seal in the elbow

Looks like old Key Terrain to me. Mostly solvent weld but you could get adaptor collars to turn a solvent socket into a push fit. I would favour using push fit around the WC as there is a lot of movement on the pan and stack. You can still get it made by Polypipe.

Guys, thanks for the resposnes. Apologies for the lack of immediate response - have been without broadband while Sky / BT decide who's issue it is!

Will have a quick look over comments and come back with any further Q's once back up and running (quickly able to borrow a connection just now).

Cheers,

Well the stright pice of pipe is not in the bend , looks like they have heated it up and pushed it over the bend, you may be lucky and be able to get the old bend out of the branch , if so clean up inside of branch and fit new bend.

UPDATED(+ new pic)...Re: Soil pipe connections (replacing old)

...so after a large delay, I've gotten around to replacing the connection into the stack (push fit Polypipe 90 degree + solvent weld straight and then push pan connector). All dead easy and working fine (result!).

New pic attached.

Having pushed the 90 degree connector all the way into the stack connector (up to the 'shoulder') my new pan is about 30mm closer to the side wall than it was before.

My question is, does the 90 degree connector need pushing in all the way or can it be part inserted...so I can get my 30mm back. This would give me a 380mm centre to the side wall.

Or...do I need to insert straight piece of pipe into the stack and then a double socket bend (can only see 92.5 deg), to give me the distance I want?

Thanks.
