peliaspastia Posted January 8, 2015 Report Share Posted January 8, 2015 I have a Damon Tuscany with a Dometic Sealand model 210 toilet. Recently after flushing it failed to close completely and water commenced to fill up the tank. Fortunately we discovered it before it filled the MH with nasty fluid. The toilet had not been holding water well for some time so I removed the black rubber seals and cleaned them (a real pleasant task!). After replacing them the toilet sealed and held water, but only if one lifts the flush pedal up with their foot. I.E it doesn't replace the ball with out a lift assist. Is there an easy fix for this? Or do I have to replace a part? Link to comment Share on other sites More sharing options...
peliaspastia Posted January 8, 2015 Author Report Share Posted January 8, 2015 I just found my Manual and there is an item called the Spring Cartridge. Is this fixable or do I need to order a replacement? Link to comment Share on other sites More sharing options...
Bill Joyce Posted January 8, 2015 Report Share Posted January 8, 2015 The spring cartridge is replaceable, but not fixable. I have replaced mine a couple times over the years. Many RV parts places have them and there is always mail order. Expect it to cost $35 to $50. Link to comment Share on other sites More sharing options...
Barbaraok Posted January 8, 2015 Report Share Posted January 8, 2015 While you are at it, get new seals and ball, since you will have it apart, might as well get new in. Barb Link to comment Share on other sites More sharing options...
Bill Joyce Posted January 8, 2015 Report Share Posted January 8, 2015 Barb: You do not have to take the top off to change the spring cartridge, it is part of the foot pedal assembly. Otherwise I would agree with you. Link to comment Share on other sites More sharing options...
oletimer Posted January 8, 2015 Report Share Posted January 8, 2015 Ours is almost 12 years old, and I have replaced it once. That took care of the problem. Fairly easy. Good luck. Dick T Link to comment Share on other sites More sharing options...
Randyretired Posted January 9, 2015 Report Share Posted January 9, 2015 Just replaced the spring cartridge on our Sealand today. We lifted the pedal for a couple of days until the part arrived. Relatively easy to replace. Link to comment Share on other sites More sharing options...
lenp Posted January 9, 2015 Report Share Posted January 9, 2015 We had a problem with ours not wanting to close all the way (the ball seal - not the water valve). Ended up having to replace the metal lever assembly due to corrosion where it rides on the water valve "button". It always operated somewhat sluggish and you had to let it "pop" back up from the floor versus slowing it's return with your foot. After replacing the lever it operates with very little effort and is very smooth. I did do a complete rebuild (ball, seals and spring cartridge) initially but had not changed the lever until later and was really surprised at how much difference it made. Actually may have been the culprit all along. Lenp Link to comment Share on other sites More sharing options...
peliaspastia Posted January 9, 2015 Author Report Share Posted January 9, 2015 Thanks everyone for your helpful replies. Looks like I get to have some more fun laying on my side in front of the toilet. Link to comment Share on other sites More sharing options...
docj Posted January 9, 2015 Report Share Posted January 9, 2015 We also have that Sealand toilet. My experience has been that it is very susceptible to mineral buildup on the ball and seal. The first two years we had the MH we replaced the seals twice and couldn't figure out why they were going bad. Then I read about using CLR in the bowl and it, indeed, does work. I haven't had any problems for the past two years. Now that we have a water softener we have probably further reduced the concern, but I'll still keep a bottle of CLR around, just in case.

And now of the fun before hand like when we were young? Barb Link to comment Share on other sites More sharing options...
