Problems turning water back on in summer camp
Recently had water turned back on at the main in our summer camp. Toilets refilled, hot water heater refilled... all worked as planned. Turned on faucet in kitchen(well... wife did) and air in the system literally broke the head off the sprayer. Now no water at all in kitchen. Kohler Revival 16109-4A unit (which has separate levers/valves for hot and cold).
Unthreaded spout filter and still no water.
Disconnected under the sink and there is water at both hot and cold inlet lines.
Attempted to back flush system from a hos. Threads on kitchen spout are not designed for a hose fitting. Tried gorilla tape and cannot get water to back flush (simply sprays all over kitchen!)
It's a very tight fitting under the sink, but if necessary I'm prepared to remove faucet unit. Not sure what to do once it's disconnected, though, and don't relish taking the faucet out of the tight space.
Is there the possibility that if I replace the sprayer head (and line) it will solve the problem?
Any other suggestions?
Many thanks!
