Shower pump Install and Up and Over Pipes

[Wrighty8]

Evening all.

I am currently attempting to self install a shower pump and I was wondering If routing the pipes into the loft and then across to the bathroom around 2.5 metres away would cause any issues?

The pipes are literally running underneath the cold water cistern, will I have problems with head with it being just under the cistern?

Thanks.

You will need a negative head pump if you choose that option

Could be a pita if you dont get it right, is it just the pipework that will be in the loft . kop

Yes, just pipework in 22mm.

I feared this may be the case although I seem to remember people doing this but maybe they had the negative pump.

I have a Salamander 50+ xtra which is positive

Why are you running it in 22mm pipe only need 15mm, connections on pump are 15mm as well as shower no benefit in using 22.

It is one of those jobs that might work if positive head pump, but nobody can guarantee it will.
Using plastic pipes makes it even less likely.
So strictly speaking, it should be a negative head pump.
Your pump is cheap and I guess you are trying to save money. You need an air free hot supply (use a Surrey or Warix flange) to avoid as much as possible air problems.

Main reasoning is basically it says to do that in the Salamander install instructions and I had some 22mm in the garage so thought that will do.

Yes, trying to save a little cash but heard good things about this pump, cheap and cheerful but does the job people say.

I have fitted a Warix flange to the top of the cylinder.

Is this 100% not going to work with this setup then?

How do I get it to work with this pump? Could I plumb it under the floor boards then across? PITA but possibly doable or should I pay £300 for a negative pump??

Thanks.

Here is where I am at with it, bit messy I agree but it's work in progress.

I appreciate most you guys are working but any thoughts on the above?
