Wild and Wet: In fact the valve is meant to be mounted horizontal, but it still works in a vertikal position. I mentioned, that there may be better solutions, because when I used the brass-valve, it was simply because I already had it in my workshop. Obviously the Jabsco may a better solution. The photos are not showing if there is a spring mounted inside the plastic. If so, there may be a problem when the water shall leave the sink. There is almost no pressure on the grey water from the sink. If someone has bought the Jabsco, it would be nice to get some feedback on myhanse, if it can be used for this purpose. :Kjeld |

We have one in each shower cabine of these valves under the sink to avoid shower water come in when the shower grey water pump is running. The inside rubber flap is the same system as Jabsco use in the toilet handpomp but there’s no brass weight on the flap and the flap is mounted in a 45 degrees position in the flow direction The acces to clean (if necessary) is easy just take out the 4 bolts. |

I think the Jabsco Non-Return valve is meant to be always-shut except when the desired flow is present. So it will need some pressure.
The hydrostatic Pressure of standing water should be 0.433 psi pr. feet. TruDesign Non-Return Valves need a Low ‘cracking’ (opening) pressure 0.41psi for 19mm and 0.29 psi for 25mm. So this will not work for TruDesign. I can't find the numbers for Jabsco valves. With the gravity valve in vertical, it should be always open, which is desired because there are no real pressure. If there is just the slightest obstruction, hair and other debris will pile up and clog the valve.

The flap is not the same as on the picture (toiletpump) but the system is the same.
It needs just a few cm of waterpressure (water columns?)to open in the flow direction

So there is no spring?
It will also be easier to clean than dismantling the Brass gravity valve. I think I will try the Jabsco valve then.

Thankyou all.
I have now managed to fit the Gulper by moving the existing water pump slightly to the right and extending the pipes to make it all work . I really appreciate the support, it really gave me the confidence to go ahead !! |
