Question on Thetford toilets

For the best advice call Thetford Customer service. The have steered me right when I called
1-800-543-1219
then you are sure you order the right part

The closet flange gasket kit is part #12524 for the Aqua Magic IV & V.
Your toilet (31661) is the 'V'.

The kit runs about $10---$15 depending on where you order it from.....LINK

There is also a Thetford Universal closet flange seal that fits all Thetford RV toilets for about $5.....LINK

Even though I didn't need the bolts, I ordered the part kit #12524. I don't trust "universal" replacements.

Thank you.

Moved to Tech Issues forum from DIY.

It's the same gasket- one just includes bolts. "Universal", in that it's the same part for nearly every Thetford.

Oh well, the extra 7 bucks won't break me.
