Toilet will not hold water

[bounder88]

Have a 2007 Boundar 35E. Seems the toilet will not keep water in the bowl. How to change the rubber gasket or should I just take in for repair

Brand/Model would be a good start

Toilet bowl seal
Could just be crud
Turn water supply off....Hold Flush Ball Open
Using your fingers rub/flex the seal gently scrapping off any crud (calcium/poop/TP)
Then use a dash of dish soap and clean the seal....rinse (bucket of water) and dry
Then use couple tablespoons of Olive Oil and lube the seal...top/bottom sides
***Clean and lube the ball valve also

Then exercise the ball valve open/close several times


Turn water on and see if it holds water



IF still leaking....new seal
But BRAND/Model for correct seal

Clean the seal as mentioned above then try Tetford Toilet Seal. Works like a charm for us.

Clean like they said and try some dielectric grease on the seal. I have found this to work the best. And if the ball seal needs to be replaced it is not real hard to do. Just get the proper parts, unbolt the toilet (turn off the water), Take it outside on a table and replace the parts. Gloves help also.

I used silicone plumbers grease, but I bet dielectric is virtually the same thing. I cleaned and greased the seal every other trip or so for quite a while. I applied a light coat to the top of the ball as well, though that's probably unnecessary.

When greasing the seal stopped working I checked, and the kit to refurb the toilet was close enough to our service contract deductible that we just let our trusted independent repair shop replace the toilet.

Other than cleaning the seal as described above, the spring on the water valve could have lost the tension. To prove this, after flush, lift the pedal a little, if the bowl holds water, that's it. Replace the spring or the valve assembly.

On the Dometic toilets use the one that has a metal shaft into the spring. The plastic ones tend to round off & not fully apply the spring tension. Google #385318162 for a picture of the part.
