...I suspect dirty contacts for the lights. I tried detergent lots of flushing and the lights above 1/4 stayed on, but the 1/4 went off for maybe 2 minutes but is now back on again. Is there a product for this?

Even on new coaches, the tank gauges are fairly easy to mess up (literally).

Probably the safest way to help clean the inside of the tank and the contacts is to flush the tank. Then put 10 gallons or so of fresh water in it. Flush 20 pounds of bagged (chunky) ice down the toilet and drive it. This is one time where a rough or curvy road is a plus. The ice will act as a mild scrubber, and will not harm the tank or plumbing as some harsh chemicals can.

Interesting idea with the ice....sounds like that should be the ticket! Fortunately I have never had a sensor problem but I will keep it in mind!

You may be careful of putting ice in. Some former posts on this forum said this caused problems by continually hitting the sensors.

I have been told that the ice may do more damage than good to your sensors. there are some great products that you can purchase that are made for this problem, but follow directions exactly.

If you use one of the wands that connects to a hose and sprays water inside the tank it will clean the contacts and eliminate the problem. You can get one at any RV store for about $10.00 to $15.00.

Honestly that is the first time Ive ever heard that the ice will cause damage. Ive been using Mr. Clean in my tanks for years along with the technique mentioned with ice and NEVER had any problems with sensors. My last MH was 13 years old when she retired and was "iced" at least once a month with no problems. JMHO

Hi Dave
My bottom 2 sensors stay on all the time on black & gray water both.
I just purchased a Sensor cleaner chemical at a local RV store in Springfield (I see you are from MO), I havent had a chance to try it yet.
You put 1/2 the bottle in with about 40 gal of water, drive around for a while to mix it up, let set for 24 hrs, drive around again, than dump and reince.
I plan to do that this week end.

I use a holding tank cleaning wand. It helps to remove anything that may become attached to the sensor probes such as toilet paper etc. Works real well.

My guages read properly most of the time. When they get erratic, I clean out the holding tank with the wand again.

I have used the chemical treatment and the ice. they both work.

The chemical stuff can take a couple of days and is a little pricey. But if you've got the camper parked for a week it doesn't take any more work than to follow the directions and dump the tank at your nest stop.

The ice works great when you toss a bag in with some water and drive to your site. It requires traveling to aggitate the tank but it's done when you get there.
