Reich tandem pump fitting (1 Viewer)

[Mr bean]

Just aboit to change water pump it has a speed fit coupling between pump and water outlet pipe can anyone enlighten me how this comes apart. This is the fitting.

 

[IRHP]

That doesn’t come apart it’s a non return valve.

If you mean how to disconnect pipe..
Ensure small black lock washer... as shown in your photo is removed.... push in white circular part towards blue body and at same time pull pipe out of fitting.

Its a quick connect by pushing the white ring. The grey C ring is locking ring.

Push the new pump to that connector.

I've just changed mine

 

[Mr bean]

Thanks all for the replies. Can see it now. Just need to go and fit it.

Changed mine the other week for one with more power. I have to turn it down now as too much pressure and loss of water.

Glad I changed it though as the other one was crap.

Be aware that this type of fitting:
Can only be used once.
And may have a right (and wrong) way up!
(If fitted with a diaphragm which permits water to only flow in one direction)

I made the mistake of fitting my connector the wrong way up,
which meant that water could only get into the pump, not out of it.
I then removed it and tried to put it the right way around to then find they are single use only.
So I had to order another connector .....

Don't quite understand your " Can only be used once statement..
Are you talking about this particular "diaghram" type being damaged by trying to push water the wrong way through it, or the push pipe fitting.
If latter they can be used again and again if removed properly !

No. Diaphragm or not, they work the same way.

The push fit connections have a toothed washer inside, so once you push them into place they ain't coming out easily and are waterproof.
To remove them you need to destroy the toothed washer, and it's not a part you can replace.

I've had mine apart on many occasions, and put it back in the wrong way round leading to some head scratching, still water tight though. TBH,even if mine leaks, it's inside the tank, so no worries.

Sorry disagree... if removed properly.. ie with grey end properly pushed in pipe can be removed without damage to toothed washer...
They are designed to be reused..

Changed the pump but still not working, can hear the micro switches clicking at the taps, will check wiring at pump tomorrow, could it be air locked in the line. Any ideas much appreciated. Thanks.

If it's a switched system and not pressurised it doesn't matter either way you would hear the pump running with a tap open whether there's air in it or not. Check voltages at the switches and at the pump with taps open.

 

[Mr bean]

Thanks for the reply, will check tomorrow.

 

[Mr bean]

No power to the taps. Anybody any idea where I might find the fuse for this.

Is the new pump running?

 

[Mr bean]

No power to the pump when the taps are opened

 

[BouncyBoatFolk]

You probably have a Schualt unit like the one in the photo on my Sunlight van. Usually, found under the passengers seat, but sometimes under a the single seat in the hab area. There's a row of fuses along the bottom of the unit.There should be one marked "Pump" 15amp? . Pull the fuse and check it for soundness.

Mike.

 

[Mr bean]

Thanks BBF yes it was the fuse!!! At least I’ve got a spare pump now.
