I ordered a 25mm plastic to 15mm copper converter from screwfix
will this actually do the job? it looks like it would fall out if it were
knocked or under pressure. Do I simply put the ends into the pipes and leave
it at that??
Yes that's the thing - there are 'o' rings inside to make the seal, and
stainless steel retaining barb things to (hopefully) stop it comming off.
Don't forget that you should have an insert pressed inside the mdpe pipe to
stop it crushing.
Can't really see what it is - but I suspect that it is an *adaptor* as
opposed to *fitting* - and that it has male bits both ends, intended to
take an MDPE fitting one end and a pushfit or compression fitting the other
Screwfix's range of MDPE fittings is rather limited compared with what you
can get at your local plumbers merchant. If, as I suspect, you want to join
a piece of MDPE pipe end to end with a piece of copper pipe, you can get
proper fittings to do this. What you have, almost certainly isn't it!
It looks like a convertor which is placed inside any of
They will do he job, but if it is just for an outside tap,
it is better to buy a 25mm plastic tap.
I've used one of these and they are very reliable - the adaptor needs to be
inserted into one of the compression fittings such as the MDPE coupler (
disregarding the insert that is in the fitting for the MDPE pipe ) and then
the 15mm into the end of the copper adaptor that you already have and
tighten the lot up
Your MDPE then goes into the other end of the fitting (don't for get your
pipe insert AKA pipe stiffener) tighten up and away you go hope this helps !
