Topic: Holding tank gauges

Regulo    -- Apr-19-2010 @ 10:04 AM
  Hi, all,

I will soon be fitting a new toilet, and while about it, I'd like some way of indicating when my holding tank is approaching full. This wasn't a problem before, just opened the eyeball flap on the Sealand toilet and looked straight down! (Whilst holding breath). Anyone fitted or got recommendations of any sort of level gauge, or indicators, etc.

Regards, Ray.

  Without doubt the best I have ever seen is the Gobius system which fits on the outside of the tank with no floats or tubes to block or jam. Not the cheapest but the best rarely comes at budget prices.

  Hi, SilentRunning,

That looks a mean bit of kit, but at £260 it's a bit out of my means! I have been looking at simple float switches, which wouldn't be a problem to install, as I have to blank off the original toilet inlet with a plate, into which I could incorporate such a thing. That would simply indicate when the tank was almost full. Any thoughts, anyone?

Regards, Ray.

  I originaly bought mine of ebay all they are is 2 pieces of stainless steel rod fixed to a plastic cap that can be screwed down to the tank top after drilling 2 matching holes then a wire from one to earth and then the other to the guage and then to power source these were bought as one of items from  ebays caravan section i must admit i have not seen these advertised any where scince i bought them.

I'm loving' it

  Clive & df,

Thanks for your input. The two rod gauge (as per caravan type) sounds good, but really is over-engineering for my requirements, as I only need to know when the tank is nearly full.

The float switch to light a LED is probably my easiest option, the only drawback being once it's fitted, access will be nigh impossible without removing the toilet and floor it sits on, so I'm a bit worried about reliability, i.e. sticking float.

It would appear that whoever built my boat started with the four stainless tanks, and built everything else round them. Access is truly dire, and to get at the rear waste tank is going to involve some destruction of flooring, there seems to be no way of easy dismantling, no visible screws, and if past projects are a foretaste of this job, everything is going to be glued as well as hidden screwed! Still, keeps me occupied, can't have me lazing around, actually floating up and down the river, can we?

Best regards, Ray.

  Think that this is the unit that Don is talking about. Very easy to fit.

Zig Gauge


All right so what is the technical name, sharp end or pointy end?

  Not quite everything, if you wanto 'Musto' clothing at vast prices you won't find them here but lots of practical things including cheap and cheerful fleeces.  Should have a range of children's bouancy aids coming in for next weekend for example.

We got our setup from the vetus catalogue, it has proven reliable and was an easy DIY fit. Recommended.
