I'm installing a new sink and have found a pretty convenient hot water
pipe that goes to the bath close by. The problem is that the existing
hot pipe is firmly fixed and as such has no play in it. This means
that if I cut a section out to install the new Tee fitting, there is no
play in the pipe to get both ends of the cut pipe into the Tee fitting.
The existing pipe goes under the floor boards, so it is not easy to
just disconnect it at one end to get some free movement. Any ideas on
how to put a Tee fitting into this?

BTW I'm spending the money saved on getting a real plumber in on a
fortnight in Greece!

Thanks for any ideas.

Is vaseline that expensive nowadays?

Several ways.
Generally, the idea is to cut out enough pipe in order that the
fittings (say a couple of straight couplings, two bits of pipe, a T) can
be assembled onto the pipe.
If the fittings normally have the pipes go in 20mm, for example, and make
an adequate seal with 15mm of pipe in them, then that gives you 5mm of slack
each fitting, meaning that you can get enough slack to put a fitting on with
only 3 fittings - which straight couplings and a T can get you.
I'd use end-feed for this, as it's more flexible, but solder ring would be
fine as long as you pay attention.
If you don't especially care about flowrate in the other pipe, you could
use 4 bends, 4 bits of pipe, and a T, to make a "U" shaped loop of pipe to
connect to.

Yes.

You need a normal tee and a slip coupler.

Cut the pipe and then a section out of it to accomodate the tee, by
measuring the required gap on the tee itself.


Cut the pipe again some distance from the tee position and slide the
slip coupler onto the pipe.

Assemble the length of pipe just removed into the tee and fit the tee
onto the other end of the existing pipe. Slide the slip coupler over
both pipes and make all the joints.


This technique assumes you have no longitudinal play (which you
suggest) but you should have latitudinal play enough to fit it all
together.


Parts are www.bes.ltd.uk no. 7200,7201 or 7202 depending on size.

There are probably equivalents in end feed if you prefer.

If the existing pipe isn't too short, you could add some bends and have
your tee offset slightly:


---- ------
| |
| |
---T---
|

Adds a bit of resistance to the flow in the existing pipe though.

The usual trick is to cut out more pipe than you would otherwise need to,
and to use a repair coupling - such as http://tinyurl.com/8kabp - which is
a long compression coupler without end-stops so as to slide over the pipe.

[The one I have quoted is for 15mm pipe, but you can probably get them for
larger pipes if necessary].

As it is for a sink and may not require much flow, consider a clamp on
washing machine coupler.

Since he's tee'ing into the bath hot feed. it's probably a 22mm pipe. Can
you get washing machine clamp-on jobbies for pipes larger than 15mm?

Please explain how that helps to tee into a pipe with no end-float.

1) Remove section of pipe
2) Add tee piece
3) Add very short pipe to tee peice
4) use flexiible to connect together.

Ah, I see! The flexible bit is to replace part of the existing pipe.

Sorry, I thought it was to connect the new tap - which could only be done
*after* the tee piece had been inserted!

The existing pipe is probably 22mm - so he'd need a flexible with 22mm
compression or pushfit fittings on both ends. Very few flexibles are full
bore though - so it may restrict the flow to the bath somewhat.

Thanks for all the suggestions. I've gone ahead and used a slip
coupler (or a burst pipe repair as its called in Homebase) as this
seemed to be the solution with the least chance of my getting it all
wrong. End result looks fine, doesn't leak and as a bonus it works.
Sink is now plumbed in and the holiday is booked.

Once again thanks for all the suggestions.
