Water level guages

My waste water tank gauge does not appear to be working correctly, showing 75% full when I know it’s empty. Is there a way to manually check the level in the tank and or replace repair the sensor?

Which Electrical system do you have; EC325, EC328 or EC500?

Hi Peter,

Not a clue, how would I know ?

I'm not aware of any manual way of checking the level in the tank.  My grey water sensors have sometimes given false readings.  I believe this is due to a build up of slimy muck and scale on the inside of the tank and therefore the sensors.  Try giving your tank a thorough cleaning and then apply some silicone sealant to the outside of the tank at each sensor to ensure road spray can't cause a short.

Many thanks for the info

Many thanks for the info. I Puricleaned the fresh pipes and drained it out via the waste tank. This seems to have remedied the situation. My ‘new’ van had been lying idle for almost a year before I picked it up so I suspect this may have been a contributory reason for the apparent problem. I’ve got some tank cleaner also which I intend to use after this trip when I get home

I think a problem we all have is getting the tank clean and then keeping it clean.  A way of cleaning the tank is half filling it with an appropriate solution and then taking the van for a drive so the solution sloshes around inside the tank.  An alternative is to fill the tank with solution and then leave it for a few days.  All I have done so far is repeatedly pass the same bucket or so of solution through the tank.  This gets quite a bit of muck out but doesn't do a perfect job and is time consuming.

1 If the sink bowl won't drain when it normally does, it's full....empty it.
2 If you open the drain valve and nothing comes out, it's empty, close the valve.

These are infallible unlike all of the sensors all MH manufacturers fit to various tanks.

Good plan , I’m obviously too keen on getting everything right on my first trip !

I'm sure the main source of gunge is the kitchen sink.  We do all our washing up in the sink.  I've recently fitted a small strainer to the kitchen sink plug hole which stops the big bits.
