I need to insert a new section into an existing underground soil pipe. OK,
so I'll cut a pice out of the old section and cut a new length of pipe the
same length, to replace it. Then I have two double-socket couplers to make
the joints. The question is, how to install the couplers. Do I slide each
one onto the new section and then slide them over the joins - or should I
unclip the rings conataining the neoprene seals, then slide the rest of the
coupler in place, and then slide the rings, complete with seals into place
and tap them home, on the coupler? The latter option should be a lot
easier, and I dare say that's how one is supposed to do it. Am I correct?

The couplers I am ising are a few years old and have been used before. I
have cleand them up. One of the couplers is orange-brown in colour. The
other is grey. The seal housing rings on the orange-brown one pried off
dead easily. However the ones on the grey coupler are not coming aff
easily. Different design, obviously. I'm wondering if they are even
removable at all. I don't want to break anything trying to force them off.
Any advice?

What sort of lubricant can I use when putting everything together? Is
washing up liquid sutable? I also have some silicone grease in an aerosol
can.

Many thanks,

Al

IME, double socket couplers usually have a stop half way through, which
means you cannot slide them fully over a pipe. As a result, you have to
be able to move one of the existing sections of pipe to get the new bit
in. If that is not possible, you need 4 x flanged connectors. Fit those
to all the pipe ends and you can slide the new bit in sideways, before
clamping them together.

Alternatively, blowing my own trumpet, I can supply neoprene sleeves
that can slide over the pipe and are secured with Jubilee clips.
However, they are only rated to 0.5 bar. Stainless steel also does not
do well in wet areas without access to air. So, I would not recommend it
in heavy clay, but it should work in a free-draining sandy soil.

The kit is part number FS400-108 on this page:

I always use washing up liquid.

Silicone grease is good when you want a permanently moveable joint
such as an expansion joint in guttering.

Soapy water is good when you want a temporarily movable joint for
assembly purposes only, after which the soap will wash away and the
joint will lock more solidly.

Rubber seals in soil pipework normally come under the second catagory.

Thanks for the suggestions, but mine don't have the stop.

I have done this. I needed to add a "T" piece for a new surface water drain.
I used two standard straight couplers and ground off the stop in the centre
so that I could slide them right up the existing pipe then back onto the new
section. I used a permanent marker to mark the spot on both old and new
pipes where the connecter should end up. It was not an easy job as even with
plenty of soapy water as lubrication the couplers were very difficult to
slide back. I managed by using a block of wood and lump hammer.

i did this (above ground) using couplers that were made for the
purpose with no ridge in the middle. i found it very hard to slide
them until I bought some silicone grease. After that they slid just
by hand (no hamemring).

The "proper" way is with a pair of slip couplings - these are designed
to slide right up the pipe. So you can get the new bit in, and then
slide the couplings into place. For longer sections, you can probably
use one normal coupling and one slip.

The couplers I am ising are a few years old and have been used before. I
have cleand them up. One of the couplers is orange-brown in colour. The
other is grey. The seal housing rings on the orange-brown one pried off
dead easily. However the ones on the grey coupler are not coming aff

The slip jobbies are often rubber with jubilee clips on each end...

Silicone is probably safest near to rubber (assuming its real rubber -
which it probably is not).

Use plenty of lubricant but don't dismantle the seals as it can be a pig of
a job to clip these in when pipe inserted.

You use "slip couplings". These are like the normal ones onlythere is no
little stop nib inside the coupling.
You slide it right on to one pipe &then slide it back onto then new section.
Mark with pencil so you knpw when it's centred up. You can convert a normal
coupling to slip coupling by removing the nib inside.

Done the job now. It was easy. What made it easy was I unclipped the seal
housings. Then the main body of the coupler can be slid easily into
position, after which the seals can be slid into place and clipped back on
with the aid of a small hammer or suchlike...
