2002 bounder holding tank problems

we own a 2002 Fleetwood bounder 36s and the gray tank backs up into the shower stall even after dumping the tanks, the sensors say the tank is empty, but after 2 showers the tank backs up. the black tank reads half full all the time even after dumping the tanks. We have tried bleach and commercial cleaning products used on rv's but nothing seems to help. Would appreciate any help on the problem.

Welcome to IRV2. Your sensors are probably not working. I don't know why your grey tank fills up after only two showers but other members will be along shortly with some advice.

You are taking too long of showers if you fill the 58 gal. gray tank up with 2 showers.
Your black tank holds 42 gal.

Check the tank vents on the roof for being plugged up with wasp nest etc.
Run water out of garden hose down it.

I would replace the sensors with a "See Level" system, well worth the money. As for the water backing up you need to do some troubleshooting to confirm the state of the tank, is it REALLY full of not.

How long does it take to drain the tank?

Nasty as it sounds, it is very possible there is a hair ball blocking your drain.
I don't like the stuff particurlarly, but the clot-busting hair ball stuff that you pour down the drain may help...also, carefully run a small wire snake down to make sure the drain is clear...

Remember that your kitchen and bath sinks are also probably dumping into the same tank thus filling quicker... Jim

If your Gray is slow in draining you may have a plastic disk when the holes were cut in tank blocking the drain hole, hope not.
If you have a 50 gal tank will fill if taking long showers, you should leave you Gray tank drain valve open when taking showers of if dry camping take Navy short showers.

Whenever I bought a used coach I always put five gal. of water in each tank along with one cup of dishwasher detergent along with one half cup of fabric softener prior to leaving, upon arrival of my destination dumped both tanks. The tanks would slosh around during the drive and help clean. I've had good luck doing this and never a problem. I hope this helps you. Good luck.
