single impeller 15mm pump

[Howie]

Hi all.

I have a problem with a water tap which has very little head from the indirect water tank. It only trickles when turned on.

I would like to install a single impellor automatic pump (possibly a shower pump) to assist the flow when the tap is turned on.

Does anyone know where I could get one of these? I have tried Screwfix, B&Q and my local plumbing suppliers. they all only sell twin impeller shower pumps.

appreciate any help....

Use a twin impeller with the impellers in parallel? More flow.

Hmm, I see. Interesting idea, - but then I would end up with a

2/3 bar pressure flow for a kitchen tap. It's only to fill a bowl of water for washing-up twice a day! Overkill? ;-)

I don't think you'd end up with twice the pressure - just twice the flow rate. A bit like having a bigger impeller running at the same speed.

Use it on the hot and cold pipes and have all the house on pressurised water. A win , win situation.

For a 15mm pump see

and scroll down to the Grundfos booster pump.
