You may remember a while back, I posted regarding not having enough pressure
at my kitchen tap (the hot side) resulting is a really poor flow rate
The cold is fed directly off the mains water (well, via a water softener)
but the hot is from a hot water tank in the loft (fed from a cold water
tank, above it)
The tap I have got seem to restrict the flow quite a lot (but SWMBO wanted
that tape of course!)
I purchased a Grundfoss home booster pump recently, and have just got round
to connecting it.
The results are poor!
Although the flow is better, it is still far far short of the mains
pressure, thus resulting in backflow problems when the hot and cold are both
If I fit a non-return valve, I think this will impede the flow too much, so
I haven't done this yet!
My next plan, is to buy a shower pump, and try that.
If I had a twin shower pump, say 1.5 bar, and I connected the hot feed to
BOTH inputs, and BOTH outputs to my tap, would this result in about 3 bar?
If not, could I daisy chain like this
Hot feed to inlet 1
outlet 1 to inlet 2
outlet 2 to tap
The reason I ask is, twin pumps seem to be cheaper!
