Water Tank Valves.
Permalink  

The selector valve on our Jayco, is a cheap three way home garden irrigation valve. I am having trouble with the entire water system, and think the only way to fix it, is to re-do the system, plumbing it properly. I am thinking of fitting two ball valves, one on the outlet of each tank to the12v pump, but access is up and behind the chassis, so thinking about making up handle extensions, and passing them through the chassis, so access to them is easier.

The rear water tank is hard to fill and gives erroneous indications it is full, I put this down to the tank breather line, dips in this line filling with water act as valves, so I am thinking about routing the breather up and through the interior of the van, then down to the Jayco manifold, so there are no low spots.

lastly the water level indicator now is showing full all of the time, have checked the wiring behind the module on the wall, so if the connections to the probes are OK, it may mean the probes are fouled, this is an awkward one as the probes are moulded into the tank plastic. This will be a check test and see exercise.

Have you considered solenoid valves instead of ball valves for the system.
Something like this perhas.

Then you can put the switch wherever you want..

Just an idea.

Cheers,

Yes I have, and I have read forum members posts on such, but those valves are not turned on and off that often, and if something goes wrong, can you just go to town and buy a replacement, and do those valves rely on back pressure to operate?
Just thinking at the end of the day, a hand operated ball valve will work.

I have had several versions of the electric tank selector - this is the latest thegreynomads.activeboard.com/t65561500/powered-tank-selector/

Parts are from the big green shed, and only select when the pump is on!. Works a treat and the bypass is only if the electric valve fails. Let me know if you have any improvements.

A lot better than laying down to get to the selector under the van.

You have a different setup to mine Iana. My tanks are paralled and empty at the same time. Consequently I have put an irrigation valve between them and find that one tank is sufficient for us most of the time.

Regarding your difficult filling, it could be that the breather tube from the troublesome tank could be restricted somewhere before it exhausts into the upper part of the filler. It may be worth checking in the cupboard where the filler pipes exit for an obstruction.

As suggested a simple irrigation valve or two with switches adjacent to the water gauges would be good addition.

I can't say I have seen a hard fitted sensor in a tank as they usually have a screw-in retainer for the sensor. Mine had been cross threaded from new so I had to fit it in place with Sikaflex. Been OK for some years and many K's now.

Hope you solve your problems
