PDQ OWNERS FORUM

Has anyone removed the tank level indicator from the waste tank? Mine is not getting a reading on the guage in the head and I would like to repair or replace it.

hi ron,

i trust your summer is going well.

i've taken ours out a couple of times but never was successful in getting it to work. assuming that pdq didn't change over the years, the sender is basically a small float on a stem. i cleaned it but that didn't make it work.

Ours never goes below 1/4 tank full after we do a pump out. We always just try to err on the conservative site since it is not very accurate.

I have no idea if the tank sensor is the same as was used on the 41, but I just cleaned it this morning. It is a WEMA holding tank sensor, I believe it is the SHS model. There is a diagram on the WEMA USA website.



This is what it looks like at the top of the tank. As per James Power's comments, I cut back the zipties to give the wire plenty of room for me to unscrew the six-sided top of the gauge. Using a large Channel Locks, it unscrewed easily, making about six or so turns to completely unthread.



The stainless steel tube doesn't allow me to see the float inside the tube, but I took a five gallon bucket and sprayed the cylinder with a garden hose inside the locker where the holding tank is. I made sure to get into the little holes at the top and the bottom of the cylinder. It was completely clean in about five seconds, and I didn't have to empty the bucket until I was done. When I turned the tube upside down and back I can hear the float move up and down, where before it was stuck.

I put four or five wraps of teflon tape and rethreaded in back into the top of the holding tank, and the wiring unscrewed itself back to normal. I will reapply the zipties when I am done with the macerator pump replacement. The whole process took maybe 15 minutes.

Hope this helps. I was a little intimidated to do this at first but it was easier to do than figure out how to post images on this forum.
Good luck.

We switched to these products. They have no moving parts.

Thanks for the help. Mine looks like the one in BillP's pictures.
