1972 Sovereign toilet keeps running
Aqua Magic toilet (original) flushes fine, but water keeps flowing nonstop. When it happened the first time I was able to stop it by pushing the foot pedal up, but now I can't stop water flow. Turned off water at source. Would appreciate help figuring out how to fix. Am not skilled at plumbing. We only use it in summer, never take it on the road. Local plumber here in Maine drains water for us each fall (and doesn't seem to know anything about RV plumbing).
