Crack in ball valve

I am NOT a tight wad. BUT I sure don't like to replace anything if I can fix it.

My Superglue fix worked until a couple weeks ago. I am now at my home base and thought about removing the toilet but instead I turned off the water to toilet and reached in and cleaned off the bottom of the "BALL". I then put s few ounces of LocTite PL3 in my gloved hand and placed an even layer on the bottom of the ball. I let it dry for a couple days but when I really let it slam the cured pc separated and was inside the tunnel so I reached down and removed it.

Not giving up yet!!! I cleaned the bottom again then scrubbed it with emory cloth then cleaned with Acetone. I mixed up JB weld and smeared a thick layer on bottom of ball. Let it set overnight. I have been using it and snapping ball into place for over a week now!!!

NEVER GIVE UP!!!

I did mine on the road last year, Aqua Magic died leaking on the floor. New 310 $150-200 why mess with it? BTW I would never go back to the Aqua Magic the 310 actually flushes.

Did you try something else or did you go back with the same 310?

took the coward's way out. Replaced the whole toilet. Literally took 15 minutes. Thanks for all the input

The 310 ball cracking goes back more than 5 years, I learned this the hard way long ago with a crack just like the original photo. Toilet is just throw away junk.

I had never heard of it til it happened to me. I have been on several Forums for many years.

Mine is 5 years old. I wonder if it’s something that has been updated.

I was very pleased my repair worked so well.

This thread goes to show, THE INTERNET IS NEVER WRONG:S Doug

I DON'T NEED NO STINKING CORRECT MODEL NUMBER, RV PARTS ARE ALL THE SAME:R

Well I admit I had a 311 (The pedal is on the other side).

But if you folks say they changed it in the last 15 years I'll believe you.

I also switched toilets.

This search on Amazon shows a lot of parts for the 310 including the ball/gate flush valve: https://www.amazon.com/dometic-310-toilet-parts/s?k=dometic+310+toilet+parts

Here's a link to the 310/320 PDF manual: https://olivertraveltrailers.com/wp-content/uploads/oliver-university/Component_Manuals/Toilets/Dometic_310_series_manual.pdf

I see several YouTube videos for 310: https://www.youtube.com/results?search_query=dometic+310+toilet+flush+ball+replacement+

Exactly what part is not replaceable?

The Amazon Parts show a ball valve kit.....BUT it is NOT for the 300 Series (300/310/320) Bowl/Base are GLUED together. Can NOT be separated so access to ball valve does NOT exist PERIOD
Other parts show (water valves, bowl seals etc are for the 300 Series
The ball valve assembly shown is for numerous OTHER models but not 310


The Owners Manual LINK even shows that there is NO part designation for the ball valve cause you can NOT replace it

YouTubes........none show replacement of a 310 ball valve. They show bowl seal replacement, water vlave replacement etc NOT Ball valve


The dang ball valve is NOT replaceable.... can not order one cause Dometic does NOT have a replacement part number for one.

It is not that difficult to comprehend......or is it???
