my thetford cassette porta potti in my caravan will not flush?

www.thetford.com.au (for those in Australia)
once in follow through to the pdf dowloads but you will need to look at products to see which model yours is then down load free repair pdf.

However if the bench type C4 manual flush my guess is you need pump repair kit. if no help send message to 'ask thetford' on page 3 of website I think.
