Can you set water pressure at the sink/tap?

mrcheez

I have a water pump that is used to send water up to the bathroom sink.

I currently have two separate "washer taps" for hot and cold but changing these for a mixer. Currently when I rotate the tap fully the water shoots out at full strength and splashes over the sink bowl, but the mixer is one of the single-lever taps and I'd like it not to shoot water out when the lever is pulled up fully.

Can I limit the strength of the water going to the mixer tap, or will a lever tap have less of a draw on the pump anyway?

I don't want to change the strength of the pump since I like the strong water in the shower.

You can fit a pressure reducing valve.

How much and where could I pick one up ?

It's been a long time since I bought one, the're available in an any plumbing suppliers.

what i use on all tap feeds as you know you will want to replace or fix when issues happen.

can also reduce pressure by rotating the tap.

Those reduce flow, not pressure.

Is there any difference? I want to reduce the strength of the water coming out of the tap whatever the "correct" terminology is

The pressure reducing valve is what you need, with it you will still have good flow.

iirc the last 1/2inch pressure reducing valve I bought over the counter in a builders merchants was €30 (€29.95?). Nice small little unit preset to 3.5 bar but adjustable if you need a lower or higher pressure with an in built filter.

If you don't open the valve /tap fully, let's say half open, do you still have the same problem?

If you want to go down the road of pressure reducing valve you will need one for hot and one for cold.

Isn't hot always going to be the same pressure unless of course someone else is using another tap?

Both hot and cold are pumped (as far as I can see in ops comments) so both are the same pressure. If you reduce cold then you'll need to reduce the hot. Unless it's a single feed pump but op hasn't said this yet

Sorry read that to mean it was just the cold water that was pumped which isn't what it says

It does seem daft to boost the pressure then to spend money to have to reduce it again?

I agree. It could be that the old taps were designed for low pressure. Maybe the new mixer when installed is for high pressure and might be ok without a pressure reduction valve

I haven't gotten the mixer installed yet, just pre-empting it in advance so that I have everything the plumber needs on hand when he comes to fit the new sink/mixer.

So currently I have two taps: cold and hot in the rotary style.

Switching them all the way open results in water coming out so fast it splashes over the edge for both hot and cold (both are connected to the pump).

I'm swapping this for a single mixer in the lever style so both hot and cold will come out of the one tap.

Of course I could just avoid lifting the lever all the way up, but I want to be covered for when the young 'uns come round and push the lever up all the way.

The high pressure feed also runs to a shower mixer. I want the high pressure here, so I don't want to decrease the power at the pump, I just want the water flow less out of the sink tap, not the shower tap.

It also refills the toilet in seconds, so I want the high speed water here too.

So in summary: high pressure pump good for shower/toilet.. bad for sink.


So "pressure reducing valve" is what I'm looking for right?

i have those reducers fitted under kitchen sink before i got a bathroom makeover with a powered pump and was told it was easier to control or switch off water supply.later i had to replace mixer tap so was handy to have them fitted.
