1.5 Bar / 2 Bar Pump for Whole House

jodaw

Would it be a good idea to:

Install a pump 1.5/2 Bar onto a softened tank fed supply. Pump to be fitted under bath and plugged into socket under bath or in attic. Alternatively hotpress extended a installed in hot press.

Pump the used to supply

- Pumped bath shower
- Uk mains fed electric shower in ensuite
- High pressure taps and fixtures in kitchen/ bathroom

Would i have any issues in installing the above. Short thread since i lost the longer more deatailed one

Hotpress is where it should be installed. You should use a Surrey flange or similar for the hot side. You should also use a suitable mixer valve to ensure water temp dosent go above 60 into the pump. You'll need 2 3/4" cold feeds from the attic tank. One for the cold to the pump. The other for the cold to the mixer.
I'd personally go with the 3 bar pump and try seperate toilets off the pump if possible. I'd also install a timer so the pump power is cut during sleeping hours. Therefore when some flushes after a 3am wee wee, the whole household won't hear the pump

Thanks for that

I was thinking one hot and cold feed to pump then tee off the bath taps to supply the mixer with pressurised hot/cold. Does the cold side of the mixer need a gravity supply?

Also could a supply from the pump supply a UK mains electric shower?

Based on my personal experience, make sure that the pump has soft start-up / soft stop otherwise the pipes and the pump creates horrifying effects, the worse been the "water hammer". Go with the dearer accessible Variable Frequency Drive pump your money can buy, otherwise you can end up buying twice.

Cheers for that looks like you have complicate matters even more

Been rethinking this.

Not sure if this could have a possible application but i would probably need to buy more than one of them things, and they are not cheap for what they are. Looks and bit gimmicky to me, and sure them little motors would not last long?

The Grundfos UPA15-90N home booster pump looks altogether more interesting.

My thinking would be to downgrade my expectations.

So fit one of these on the hot after the vent to add extra pressure and flow to all hot taps. I think this would be enough to allow me to use higher pressure taps etc. Also this pump would feed the hot on a simple mixer shower with simple showerhead. Drop another gravity feed to cold side of mixer.

As far as the current pumped electric shower i was thinking a few options:

1. Buy a Mira QT Elite. Quieter but i dont think it looks very reliable and reviews not great.

2. Fit a showerpowerbooster pump in the attic on the gravity line to shower and replace pumped shower with UK mains electric shower. Maybe : https://www.amazon.co.uk/Bristan-SM285-Smile-Electric-Shower/dp/B00CHEYPXA/ref=sr_1_1?ie=UTF8&qid=1462743170&sr=8-1&keywords=bristan+smile

3. Change existing gravity feed to shower, instead tee off mains with the showerpowerbooster inline on this feed ?


Any help greatly appreciated

You can get these sort of tanks for under the stairs, add a pump to it

it'd save upsetting existing plumbing
