Would like to eliminate the wax rings on the toilets in my house. Would like to use the wax-free toilet seals. Understand there are a few different brands on the market. Has anyone compared the performance of the different brands?
Fluidmaster has the #7500, #7503, and #7504
What are the differences between each of these 3 part no's? Fluidmaster website does not provide any info at all. Assume the 7503 is 3" and #7504 is 4"? What is the #7500?
Fernco also makes a seal (#FTS-3 (3") and #FTS-4 (4")).
Do any of these have have "better quality" o-rings, seals? Is one brand "heavier duty" than another? Will one last longer? Any comments anyone can provide would be helpful.
