Help with Hymer plumbing fitting (1 Viewer)

[peterc10]

The Twin submersible pump in my Hymer B678 stopped working late last year and today seems warm enough for me to try to replace it. Seems very easy BUT I am struggling with getting the non-return valve off of either the old pump or the hose it is attached to. Below is a photo of the new non-return valve, which is exactly the same of the existing one. What do I have to do to get the old one off. I have tried pulling out the little grey tab between the blue and white bits but that does not seems to work and I have tried pushing it in, but it won't go in. So what is the knack of releasing this please?

Did that Brian, but still could not pull it off. Is there a knack?

The old fitting has the grey clipe still in. Does that mean that I put them back in when I eventually get the thing apart?

Yes, remove the clips then press in the white collar towards the blue fitting that will release the pipe

They can be awkward Peter but just push the white part in with your thumb and pull hard on the pipe with the other hand.

P.S. make sure you push the pipes well in when refitting

Thank you all. Sorted out now. Easy when you know how

I did not have any problem in pushing it well in Brian
