The bar mixer I am fitting is supposed to have flow restrictors in the
two inlet adapters when used with a combi boiler (i.e high pressure).
BUT, it has arrived with some of the small plastic restrictor parts
missing.
Before I go through the hassle of returns/complaints etc, would I
obtain a better result by using something different in the supply
pipes?
Such as an adjustable pressure reducer / balancer.
The instructions say when you have the restrictor, always use the
shower on full. Seems a bit crude to me.
I guess the pressure/flow needs to be controlled so the inlet ports
dont have to be nearly closed all the time.
Also, the inlet pipes would at present be unrestricted cold mains
inlet, and restricted flow (by the combi I guess) on hot,
i.e. turn cold/hot taps on full, cold discharges faster.
Would a balance be a worthwhile addition ?
TIA,
Simon.

Hi,

I'd have thought the flow restrictors are used when there's a big
difference between hot/cold inlet pressure, could be worth ringing
them up to ask.

In any case it might be easier to retrofit a gate valve on the CW
supply to the mixer somewhere if need be, makes it possible to adjust
flow without taking the mixer off.

cheers,
Pete.
