My 1980 Hilo funchaser toilet is not filling up with water, any suggestions ��

Just recently opened camper 1980 funchaser, ran water lines, all running well except for toilet and shower hose, any suggestions as to what may be hindering the water flow 🙏

Luke, I moved your posts to their own thread in the plumbing section because I think you may get better responses here.

My toilet only supplies water during a flush, but it was somewhat blocked one spring when I de-winterized it. I never did figure out what the blockage was, but it was something that built up behind the flush valve.

Thanks for your help jack ��

Thinking about this, you MUST have a blockage in the toilet's flush valve. Possibly, the trailer's water pump does not supply enough pressure to clear it. You MAY be able to force the blockage through the valve if you hooked your trailer directly to city water without using a pressure regulator/restricter at the hookup. The same would apply for the shower.

Give it a try, but don't leave the trailer hooked up to city water pressure for a prolonged period, because you SHOULD use a pressure regulator with city water.
