Dometic-Compatible Flush Ball Seal for 300 / 310 / 320 RV Toilets - Comparable to Part Number 385311658 - By Mission Automotive
by Mission Automotive
Hey my bowl leaks out app 2 qts in 2 min. Just going over things as u know. No smell what so ever but thought I would replace as a matter of PM annually. That should be the part for 22 bucks or so but that seemed a short life span of 2 yrs. Any advice forum?
Don if u r out there I may really need you here and will provide gloves. It may just need cleaned but i will need the wife to do this first but what do you think?
Very little use?
Tommy, that seal may just be drying out a bit and getting stiff in which case it needs to be lubricated/conditioned, or it may need to be cleaned well, or both. Unless it was defective from the start, I highly doubt you wore it out.
I'd try cleaning the black rubber seal well and then get some Thetford 36663 Toilet Seal Lubricant & Conditioner and then see if that cures the leak. Mine slowly leaked out over a month or so and the seal dried out a bit. I cleaned and lubricated it up and it seems to be fine now and holds water for months.
I'll be glad to come over and replace the seal if need be however.. I'd just try cleaning and lubricating first.
Note that I think Vaseline would work.. I just do not know if long term that it would not react improperly with the rubber whereas this Thetford stuff is special purpose just for that application so no risk I suppose. Next time I do mine, however, I am going to get some silicone Plumber's Grease at Ace Hardware for ~$3.00. I am sure it will not hurt the rubber seals as that is what it is made for. That will lube and condition the seal well and probably last longer.
Check out Thetford 36663 Toilet Seal Lubricant & Conditioner ... it is about $12 on Amazon.
