Toilet won't shut off, do you know why?

[Zimectrin]

Sealand Traveler Model 510+ toilet.
Full time use.
Three years old.
No other problems or repairs.
Cleaned each week.

When we step on the pedal the flush ball opens and water flows. If we remove foot the pedal snaps up and the water shuts off. If we use our foot to raise the pedal slowly (our usual method) the flush ball will close but the water will not shut off completly. This just started this week and there has been no event to suggest the cause.

This could be a problem!

Seems I need to adjust, clean, tighten something.

All suggestions, ideas, comments, experiences welcome.

Will post the 'fix' when discovered.

Thanks in advance.

I've had this problem. A squirt of WD40 on the valve shaft fixed it. Didn't even have to disassemble anything.

If it continues to be a problem, you will have to replace the fill (flush) valve, which is about a $50-60 part at most RV stores. It's not too hard if you are mechanically inclined.

Just a thought here but I had the same problem with my Theford last summer and found the problem was high water pressure. I put a pressure regulator in line and the problem went away.

Sounds as though the seal is not seating due to the easing down of the pedal. Let the pedal shut hard for a few days and see if it reseats itself.

Steve, we also have the sealand and they're a great unit. After I flush, lift the pedal to add a bit more water to the bowl, that's the way ours works. At first I didn't know how to add water after flushing, then I finally read the instructions. Hope you get your problem fixed ok.

Best regards, Jim
