Thetford 42137 Aqua Magic II Base-White

OEM replacement item. All needed parts included, easy install with basic tools

Im so happy that my toilet finally holds water! Its one of those things that you should've done a long time ago. Im happy with the shipping and thankful it came with all the accessories needed.

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.

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.

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.

Our ball valve wasn't closing properly on our Thetford RV toilet model 42070. It wasn't holding water. After looking at our options we decided to get this base because there was nothing wrong with the bowl.It arrived and we read the instructions. They are not as clear as they could be but we figured it out. Today we decided to tackle the job. We followed the instructions and removed the toilet. We took it outside on the patio.Removing the bowl from the base is fairly easy to do.However, putting the bowl on the base was problematic. The bowl would go on the clips and we could turn it but only one hole lined up. We tried several times to no avail.I came on here and read a review that said to raise up the plastic clips. We did that using a wrench under the clips. You have to do it carefully so you don't break them. Once we raised them sufficiently we were then able to align the holes and reassemble the toilet.What should have been a half hour job took us over two hours. Now our toilet is as good as new for less than half the cost of replacing the whole toilet!

Ten minute toilet swap. Comes assembled with new gaskets. It was also delivered 2 days before it was supposed to.

easy to install we used YouTube video

Fue igual a el que tenía buena compra

Excellent solution for fixing an old toilet the parts purchased seperately would cost way more. Easy to install and works great, highly recommended.

We have a porcelain Thetford toilet which continued to leak even after installing various "kits". Decided to buy the whole new assembled base and it is literally like a brand new toilet with the pedal functioning as it should without any leaks. The installation is not as easy as it appears it should be though. Everything goes together well enough BUT, centering the bowl on the new base and screwing it down is a royal pain. This part took me an hour of maneuvering until I got it right. However, we are still very happy with the result and feel confident in the toilet and it's ability to do the job without leaking.

I have never had an negative comment to make with my amazon purchases, but this was next to impossible to install.The plastice pieces on the top of the toilet base were not the proper size, the pieces were not even cut properly and had jagged corners and were to thick to twist the toilet bowl onto the base.After 2 hrs of tryng to fight with it we managed to bend tbe plastic just enough to twist it but hurt our hands badly in the process while trying not to break it as we had to use such force, never have we ever had an issue installing anything like this toilet base.This base should not have passed any safety checks nor should it have left the factory it was made in,Total disappointed on the quality, and surprised you would put such a mess out for sale. Had to give 1 star to be able to post my review, this product dosn't deserve even 1 star.

Fit our porcelain top rv toilet, super easy to change. Our pedal broke on our old toilet. This took us 30 min to change
