Bailey toilet flush pump!

Sandgroper

Hi!

Getting ready for summer fun and I am experiencing what I guess might be a regular problem. I have my Bailey Olympus 464 van serviced regularly in October but on filling up the toilet flush today the pump refuses to work.

It maybe just that the pump is 'frozen' and needs a twirl to free it, but how do you get at it? I guess that the inner fitting can be removed somehow but I don't want to break anything!

First though, I will check for an electrical feed. The reed switch was replaced a couple of years ago. How much are they?

Any knowledgeable help would be appreciated!!!
