Some fine sand got into our water pipes, and we have lost pressure at three places in the house (both kitchen knobs (which feed one spigot), and a "cold" knob in the bathroom, although "hot" works at full pressure, and they both feed the same spigot). I have already cleaned the sand from the bathroom aerators (This restored pressure to the "hot". The kitchen does not have an aerator.). What is the best way to restore water pressure to these problem faucets?

Thanks,

I would start by shutting off the angle stops under the sinks, disconnecting the supply lines at the faucet(putting the open in a bucket) and then turning on the angle stops to flush out the supplies(and verify you have good pressure/volume there). If the supplies seem to have been clear, the faucets should be disassembled and cleaned.

I assume you have a water softener, and if so, the "sand" is actually the softening resin because the softener is broken internally. IF this is the case, it is a long term process to flush it from all the pipes and fixtures, including the water heater, after putting the softener in "bypass" mode.

If HJ is right look at the 'sand' under magnification. If it's smooth and round then it's water softener resin. Sometimes it even has activated carbon mixed in with it (black and rough).

If you just spread some on the countertop and it looks "golden" then it is resin.
