I'm not taking it as 'red' what I was told - that's why I'm asking advice on here :) Basically I just need to know now what pressure pump to get - would a 2 bar be sufficient?, just to refresh the application: mixer shower with overhead rain shower & hand held shower (it's not a...

That's not what I was told by the company that installed the bathroom (or the manufacturers spec for the shower (the company wanted too much extra to supply & fit the pump, when I can easily do it myself) The output of the pump will literally be only about 1 metre away from the shower -...

I'm going to get this one (as I get 3% discount at screwfix & am ordering a load more stuff at same time, so will be 3% off total order :) ) http://www.screwfix.com/p/salamander-pumps-ct50-positive-head-twin-shower-pump-with-isolators-bar/46231 or this one...

That's wayyy out of my price budget, Its only for one shower, positive head with a very short pipe run from pump to shower - do i need 3 bar? also don't want something that's going to empty my cylinder in 5 mins

Cheers - 1.5 bar?

I have just installed a new shower, but my trad system water pressure is insufficient & it requires a pump - I know how to fit one properly ok, just need advice on which one to get & where from to suit my requirements. Both my hot water cylinder & cold cistern are in the loft - 22mm pipework...

Anyone please?

I have decided on a shower cabin with overhead rain shower, separate hand shower & body jets for my new bathroom installation. I initially decided on the insignia GT9001 for it's features & dimensional requirements etc. Obviously there are quite a few alternative makes with similar features...

I have not yet wired the pump directly to the boiler, but it seems to be behaving itself now, holding pressure & not locking out. I have noticed it only seems to lock out if the boiler thermostat is turned beyond say '3:00' - but like I said it had the new Siemens control unit fitted about 2...

Yes this boiler does - and I believe this is where is should be connected, so as to have the pump over-run controlled correctly - as the guys previously explained to me

This is the pipework by the zone valves, I assume this is the filling valve: Also I have checked point-to-point continuity & my system is wired identical to this schematic. As you can see the pump is terminated in the junction box & not boiler?:

Excellent thanks, will do

Great thanks, I think the system needs a good bleed when cold & maybe balance out the radiators too. Yes there is a filling loop right near the valves, or what looks like. okay so when cold - let the expansion vessel down to 0.5 bar, use filling valve to fill system upto 1bar on gauge...

Thanks a lot for your help can you upload photos on here? - if so I'll take a pic and Stick it up. There is a lot of air in the system now rads are gurgling like mad, there is 1.5 bar of pressure in the expansion vessel - but the pressure gauge on the boiler outlet reads zero! i think i...

Well there's one issue then!, my pump isn't wired directly to the boiler, it's wired to the S plan junction box. there is some additional pipework around by the two motorised valves, upto the boiler pipes so that may be a bypass
