rear exhaust toilet - changing wax

[gravine]

Hi - other than it is horizontal and not vertical, is there anything different in changing the wax for a rear exhaust toilet?

 

[LiQuId]

yes, quite different as there is NO WAX..

 

[gravine]

Wow. There's a quick education. Do you know of any good how to sites for this one? Thanks for the reply

That depends on whether it sits on the floor or if it's wall hung.

Sits on the floor

If the flange is at the correct depth and screwed to the wall then a std. wax seal would be fine.

Rear discharge toilet, use a foam ring a Wax will wear out fast.

Sorry Liquid I don't agree. As long as the flange is set properly and secured in place the toilet won't move, being supported by the floor. Movement of any toilet will cause a wax seal to fail. If the toilet was wall hung then there would be some movement because the toilet is actually supporting the weight of the user. In that case a foam gasket is required.

I see what you are saying, and as you know I respect your opinion but my experiences with this are that its not the toilets movement that causes the seal to fail but rather the flow of the discharge. I have encountered this on a few occasions where the gnereal handyman on a commercial job has replaced a foam ring with a wax one ( for reasons never quite clear ) and have found that the lower side of the wax has worn away when I removed the toilet. the upper half was unnafected. after only a month and a half one toilet was leaking badly andother only slightly, and upon removal of the third it was close to becomeing a leak.... these WERE all wall mount toilets mind you.

these are my experiences and the reason I would only install foam on a reaar discharge, but you have had other experiences, and likely more experience So I'll not doubt your knowledge on this.

I would be curious if the OP does go the Wax route to hear a progress report a few months later.
