THETFORD 42137 Aqua Magic II Base-White

Worked perfect, no problem, easy to install and a great price. Highly recommended it and the company

This is the exact replacement for my Thetford RV toilet base. It is fairly easily installed, although the instructions are sort of cryptic - they are trying to do too much on a small document. I had to remove and replace mine a 2nd time because I installed a gasket upside down!The quality of the hardware included was good, again identical to the original.

I simply can't comprehend how a defect like this couldn't have been caught at quality inspection! It is so obvious and has wasted my time and effort. Thetford ... not a good effort on their part.Ok returned this one and ordered another ... the new one was packaged well and did not show any damage. Installation however, was another issue. For some reason the place where the top seal is placed in the old base was formed into the plastic of the base. The new version has a small circular piece that gets inserted into the throat of the base ... but it will not stay put ... keeps creeping out making it impossible to attach the bowl to the base because one cannot compress the bowl onto the base with enough force to both seat the insert and twist the bowl into the 4 little "fingers?" that hold the bowl to the base. Two little screws were need to hold the piece into the base so it would stay put. Next issue is the little fingers that hold the bowl to the base. These did not stand high enough to allow them to slide properly to connect to the bowl to the base when attempting to twist onto the base. A pair of channel locks were used to bend the little fingers upward so that eventually they would clear the bottom of the bowl allowing the twisting of the two pieces together to actually happen. So a 30 minute job turned into a couple of hours and wasted colorful language phrases that could have been put to better use.

Yeah! This is the best way to fix the RV toilet. No small parts to piece together in gross areas, just buy this brand new unit and put the bowl on. Make sure to re -tighten the mounting bolts at the floor after sitting on it.

It fit my Thetford crown just fine. It was a little hard to seat the seal.. when you turned the crown to lock it on to the base, it looked like the seal was off a bit, but it wasn’t. The screw holes lined up, the constant kick on of the water pump from the leak is gone, and that’s a win. Don’t forget the lube for the tabs and seals! 2 person job done in an hour or so. The instructions are pretty much garbage but it’s pretty basic even without them. If you have a little general fix it skill, you can do this.

This is a good direct replacement. Had a firm initial fit, took some coaxing to get it on. Hookups was spot on, well pleased with this product.

Why did you pick this product vs others?:Brand is perfect Mach whit my other top part

That old base blew the water fitting off the back. This was a direct replacement. We'll see if it stays together where the other did not.
