electric shower install
have plumbed in electric shower and as soon as open isolation valve (And prior to turning on power ) water came shooting out the inlet joint
( the inlet is not threaded ) . the inlet connection used was recommended at local plumb centre of a plastic type compression elbow.
Any help greatly appreciated.

Oh deary me. Did you read and follow the manufacturer's instructions?

I've never heard of a plastic compression elbow. Have you perhaps fitted a plastic push-fit elbow? If so, remove it and fit a brass compression elbow, like the manufacturer says. Then dry out the shower with a hair dryer. Then go back to the place where you bought the plastic elbow and insert it into the assistant who misinformed you.

I bought a Creda shower recently and this had a plastic inlet pipe, no thread. I used a reusable push-fit plastic elbow which works admirably. The only problem I have with the push-fits is to make sure they are pushed all the way in, else leaks can occur.
Slip - is it possible the fitting was not pushed on fully ?

Electrics is more my thing (and lots to learn there too) but I believe our freind softus was alluding to the fact the thread is required on the elbow fitting and uses compression to seal the brass olive onto the inlet pipe which in my limited experience has never been threaded and is usually plastic about an 25mm long.

Let's get one thing straight - I'm not a friend of either you or slipdigby.

I haven't "alluded" to anything, other than the fact that the OP is incompetent.

A correct, but beserk, description of what happens.

From experience a compression fitting onto a plastic pipe can be a problem if the plastic deforms too much under the olive. This can cause the joint to weep if the nut is tightened too much.
Putting a "mushroom" of copper into the plastic pipe was a common practise to prevent the plastic deforming under the olive.
