Question on water pressure

sunnyday1234

Hi

I have very low hot and cold water pressure in my kitchen tap but the other taps downstairs are fine (bathroom and utility room). Are all downstairs cold taps on mains or just one in kitchen ? If so, what could cause the kitchen one to be poor for both hot and cold and the others are fine ?

Normally the only fittings supplied direct from the mains are the kitchen tap and the bathroom toilet cistern. Everything else should come from the header tank in the attic, so if you have a single kitchen tap with a cold water and a hot water knob, the cold will be from the mains and the hot from the immersion cylinder in the hot press. That will also be the case if you have two separate taps on the kitchen sink, and the result will be that you should always have more pressure from the cold tap than from the hot one.

Given that I would say that you have a very low mains pressure, and that is entirely possible.

It's most likely the mixer tap causing the problem. Sometimes there is a restrictor inside the tap. This may need to be removed. Or possibly you need a new mixer tap.

Check there are no isolation valves under the sink which have got closed off a bit.

Is this in compliance with LA regs?
If so can you provide a link?

Is it not just kitchen tap and storage tank?

Where's the logic in feeding the bathroom toilet cistern from the mains? If the water main gets cut off, it means that one flush and the cistern is dry while the tank in the attic is full. In order to continue to use the loo, you'd need to flush it using jugs of water filled manually from the bathroom sink - makes no sense.

I though the cold tap in the kitchen and the attic tank were the only places fed direct from the main.

and the cold tap in the bathroom sink - brushing teeth etc

M.T.D

When you say low water pressure do you mean low flow rate or actually low pressure.
Compare your different taps, put your thumb/palm over the tap out with the tap turned on. How easily can you stop the flow in the kitchen compared to the other taps.
If the cold is mains fed, even if low flow rate it is hard to stop with your hand.

If both taps (hot and cold) at the kitchen sink are low in pressure check if there is an 'aerator' fitted. If so it may be blocked with some sort of debris/rust or whatever!

thanks guys.I have a mixer tap in the kitchen and both hot and cold flows are very poor. takes ages to fill the sink
. Other taps are much stronger in hot so would this point to a tap issue as all hot comes from the same source ?


I have an outside tap at back of kitchen and have used a power washer with this, is this mains fed ?

If it was poor mains pressure, how could i resolve this ? Its a serviced site so would the council take a look ?

How can i check if there is an aerator fitted ?

Aerator is the little mesh screen on the tap that 'diffuses' the water. It can get blocked with sediment/mineral build up. Simply screw off to check, some may require a spanner or similar!
