3818 tank monitor to include waste?-gctid814950

Hello brain trust!!

Had another crappy situation. Thought my water tank was only half full and then bam, light goes on.

Wanted to look at gauges for it so that I can see where it is at. Then I see on the water gauge on the front of the lower helm ( One you press the button and it shows you the level the water tank is at) ... there is a spot to put a second button?? Would it work to have a sender put in the tank and put the wires to that gauge?

Thoughts?

Personally - NO! (to the internal tank sender) Black water tanks are horrendous and I can't imagine that your is any different. If it's a plastic tank (which I imagine yours is), then use one of the external tape mounted sensors that "see" through the tank wall. Like this: http://levelguardproducts.com/marine-rv/index.php There are other ones out there, just need to look around.

Yes to your question

Did install this Spring and works great

Used holding tank sender from WEMA Measure depth of your tank and order longest that will fit.

Reason I was confident in doing this in holding tank is that installed similar tank sender from WEMA in plastic water tanks that I installed four years ago that are working great.

The holding tank version has very nice and robust flange that through bolts to flange ring mounted inside of tank. The sending unit is installed into a thread hole in the flange that makes for easy removal and cleaning - if needed.

Knowing the actual level is a real plus not only during the normal use - but to confirm it is empty

I did the same thing a about 5 years ago. Used a WEMA sender as well. Use the old battery voltage selector switch as it had been replaced with a battery monitor. Works great for me.

I recently installed a tank monitor for the holding tank. It used the aluminum strips for sensors on the outside of the tank. Mounted the unit at the lower helm. Very accurate, now the tankwatch system lets me know when I'm roughly over half a tank, but the the Snake River system gives an accurate level indication.

The existing fresh water tank monitor has a drill mark and a lable saying tank 2. Could one not just hook up sensor for black water tank to the tank 2 leads on back of the meter (assuming there are separate leads).???

[RDOIII]

There are no Tank 2 Leads - you must run your own. It is only a label for one to be installed

Ah thanks!

I just did this but with two water tanks had to run wire from water tank 2 to panel here is the trick the original switch puts power in gauge and light so you have to do a little rewire so that when you push the tank 1or 2 button the sender wire is connected and loose the automatic light
