Do I need a flange?

[Revelation]

Hi guys,

I recently installed a Salamander pump to feed my shower. I pretty much followed all the instructions to a tee, but have not bothered installing a flange.

I was wondering, since the pump is only feeding the shower and not the whole flat, do I still need the flange installed?

What happens if I don\\\'t install a flange? :s

Thanks for any help!!

You run the risk that
a) it won't work
b) you damage the pump

Thanks ChrisR,

It was actually working great until today - the hot water suddenly lost pressure, so I am assuming it was due to the flange as this affects the hot water (right?).

Can you explain exactly what task a flange is meant to perform? Am I right in guessing its like when you let water flow out of a water bottle, it can be speeded up made to flow much quicker if a hole is put into the top of the bottle.

Thanks guys.

No.

One risk is that you suck air down the vent pipe. Then you don't get hot water, and the pump overheats and leaks thereafter.
