I winterized KoKo by opening the sinks and bath valves and blowing compressed air into the city water filler. When we got ready to go in the spring, we found both sink faucets clogged with the residue of western water. I really should use our water filter. No amount of cleaning and soaking would place the bath faucet back into condition, so we replaced it with one from Lowe’s.
You need slim hands to get to the hose fittings under the cabinet.
