Unsure how old your tank is?
The manufacturing date can be found on the bottom of the waste container.
How do I know which toilet model I have?
Look for the product label located near the toilet bowl, it can often be a bit hidden.
Thetford designates its tanks in series; if you have a toilet called for example 263S, then you have tank 260 and the seal will work.
Still unsure?
Take a picture of your tank, look for any labels and take a picture, then contact us and we will assist you.
