Good morning all!!

How do I know if I have a Thetford V toilet or a IV.

Need to replace the blade gasket and see each model has a different part #. Was hoping to take the part with me to the trailer this weekend. Based on the year of the trailer does anyone know what model toilet it is?

Thanking in advance for anyone who might know!!!

Welcome to the Forum from Western New York State!

I can't give a definitive answer to your question, there are both hand flush and foot flush mechanisms for both models, but if you look on their website to compare them both, it may be of help.

"If" you had the TT available.....there should be a model number sticker located on the 'back' of the toilet base...., using a small mirror should allow for viewing the sticker info.
