Bathroom and kitchen faucets

[harmony68]

Low hot water pressures coming from bathroom and kitchen faucets. Anmy advice would be appreciated.

Is this only from the sink faucets, or is this problem also evident at tub and shower valves?

This applies only to the sinks. The tub and shower faucets are not affected.

Check the aerators. It happens here when the water company decides to do something with the pipes in the area and stirs up sediment.

If it is only on the hot side, it can't be in the areators, as that would affect cold flow as well.

I am guessing that it is mineral buildup, either in the supply valves under the sinks or in the hot side cartridges.

As I said in the other thread, start with a cheap plastic supply, attached to the shutoff valve under the sink. Turn the valve back on while directing the flow into a bucket. If you have good pressure there, then check into the hot cartridge. If not, shut the water off to the whole house and disassemble the supply stop.
