I live in a mobile home that has no hot water in the kitchen or bathroom sink and has hot water at the tub, but no pressure. Everything worked fine a couple of days ago at the bathroom sink and the tub, but has been losing pressure at the tub for a while.

I live in a mobile home that has no hot water in the kitchen or bathroom sink and has hot water at the tub, but no presure. Everything worked fine a couple of days ago at the bathroom sink and the tub, but has been losing pressure at the tub for a while.
Is the cold water pressure OK?
Sounds like some crud broke loose and is now clogging the hot water system.
Shut the water off to the unit . Start with one valve at a time. Open up the faucet and check and clean the inlet ports in the cartridge. Now turn the water back on for a fewinutes to flush out the supplies and open valve body. Reassemble the faucet, sahut the water back off and move on to the next faucet. Do the same thing on any faucet that has a problem. Let me knowhow you make out. Good luck, Tom
