Shower pump connections.

Hi guys, just curious to know of how some of you guys pipe your boosted power showers. Do you always take an independant cold feed from tank in loft and how do you go about taking a hot supply do you connect a surrey flange or do you just tee in to open vent pipe.

For cold, use a separate feed from the storage tank so the supply doesn't get interrupted,

For the hot, have a surrey flange fitted to the cylinder to prevent bubbles entering the line of the hot.

There is propper ways and there is impropper ways.

Fingers is the propper way.

Many do what i suspect is done on yours(judeing by you asking) but this is wrong. It pulls air into the pump can cause pump cavitation and ultimatly shorten the life of the pump.

Yes thats the completely correct way, but being completely honest i have never seen a surrey flange. I always see people just tee in on the vertical coming from the top of the cylinder but either slanting the tee at 45 degree angle or having it looking down- would that help in any whick way.

You cannot see a surrey or warrick flange once fitted. to the lay person it looks like a T

if you take it off the expansion its wrong...


What i use to do is sell cylinders with an extra tapping and plumbers would use hollowed out 311's and a length of copper to make there own flange. I would supply the 311's as well. The price is considerabilly more cheaper than a surrey or warrick flange and every bit as good.

It was also a brucy bonus as sometimes that 2" saved on cylinder height made all the difference to plumbers.

well ive never even see a tee off the top of cylinder either, thats a good way about it. Ya its defo wrong but works in many cases id say- saying i seen it so much. Have you ever seen it installed that way as such.

Oh and i dont think the method you would use would be cheaper if adding pump to an existing cylinder, but great idea in a new installation.

My brothers house was plumbed by a cowboy who made a pox of the half of it, but even they had the cop to fit a surrey flange for the water pump.

Still though - different strokes.....

ya when i saw the tee on the horizontal got me thinking, although after posting here i rang a plumber i know and he says it'l work, said its not right but he knows for a fact it works fine as his own is plumbed that way and has held for last 7 years.
