Hi,

Say I'm going to have three lengths of polyplumb pipe connected by
two right angle pushfit joints.

How do I measure the correct lengths of pipe to allow for the
amount of pipe that goes into the elbow?

Once the pipe is pushed into the elbow, can it rotate or do I have
to get the turns right first time? One elbow will be in horizontal the
other will be in the vertical.

I have bought the correct pipe cutting tool. Is there a knack to
pushing the pipe into the connector (I know I need the internal
support sleeve in the pipe) or do I just push the pipe in and it will
go in "square"


Thanks

Clive

If Polyplumb is like other makes of similar pipe which I have used, there
should be marks on the pipe at approx 1" intervals which indicate how far
the pipe goes into the fitting. So you cut it off level with one mark, and
push in it until you can *just* see the next mark. If you need to cut it
between marks to get the exact length you need, make another mark with a
felt-tip pen the right distance from the end of the pipe to make it easy to
check that you've pushed it right in.

You can usually rotate the pipe in the fitting if you need to.

Yes, you certainly need to put appropriate inserts into the ends of the
pipe. If you line up the pipe with the fitting *reasonably* squarely it will
go in easily enough.

It's been a long while since I used any plastic pipe, but I thought
the inserts were only required when mating to compression fittings.
Are they needed to make standard joints to other plastic fttings ?

Very much so. You might get away with it at low pressure but at high
pressure the joint will either leak or blow off.

Polypipe certainly allows the plastic joints to rotate. I have used it many
times.

Yes - you need to support the pipe - and make sure that it is round rather
than oval - in the region of the grab ring and O-ring seal.

Oh, fair enough. To be honest, I use plastic as the exception rather
than the rule and generally only use compression on them. I prefer
copper, soldered or compression, if only because I have a load of
fittings to suit.
