Hi!!
I have purchased a Thetford C403 toilet. Now I need to buy a water pump to supply the flushed water to it, with pressure/Flow rate according to the WC inlet specs.
It would be a NOT a submersible water pump.
Can anyone help me?
What water pump do you recommend?
Thank you!!

Our pump for the Thetford loo seized up. We just got a generic one online, at no great cost. No idea about its pressure/flow rate: I suspect one size fits all because it said “fits toilets x y z”.
Meanwhile, until you get the pump, a small jug for water and a bottle of dettol to add a splash means you can use the toilet by emptying the jug around the rim.

With reference to the Thetford website, I meant what model number pump do they say is the one for the job.

The Thetford pump will cost much more than any of the identical ones online, but that’s your choice. OH bought & fitted it, it said “suitable for Thetford models x y z”, the numbers included ours.
I think you’ll find that the model number is what’s listed rather than bars. Replacing the seized one was fiddly but it works fine.
