here's one for the tank water residents..

I've got two systems- a pressure tank(bladder inside) type old water pump and a new electronic water pump.

Question is -- how do I adjust the pressure of the new type electronic water pump ?

The old type,,toilets fill slowly and allways cut off at the correct volume.

New type , toilets get a rush of water(pressure too high,maybe) , and so keep overflowing ..

on the new type electronic water pumps there is a small slotted nylon "thingo" like a flat headed hidden screw at the end of the pump bell housing . Is this anything to do with the adjustment?

Thanks

Bruce.

If it is a float-based system then you can of course adjust the level of filling via the float lever adjustment, but then it will not fill fully with the older system. The float lever should still shut off quickly regardless of how much water volume/pressure is applied as it is a mechanical seal, so I do not understand your predicament.

I think that seals are not suited for higher pressure and they let water through.
Possibly they got worn out or they were not designed for this pressure.

Interesting if you can reduce pressure on your pump?

Alternatively you can install permanent in-line pressure reduction device and adjust it to match pressure from old system.

Thanks Guys ,

I think there is a dip switch in the controller that can adjust the water delivery pressure,,I'll speak to the water pump man tomorrow..

nothing to do with the cistern --- it is governed by a float switch/cock..

but my guess is because the water pressure is gushing in so fast with this new high pressure electronic pump , then is sort of overflows before the float cock can come into play . the slow ,low pressure pump just gradually fills the cistern and the float cock can cope with that ...

all 3 of my cisterns do the same thing--ok with the old low pressure pump ..

thanks for thinking

Normally there is a tap on the wall just below the cistern, throttle the water back by half closing the tap.

Bruce, old age is terrible, try to avoid it!
