Holding tank digital display

[Stevej3658]

Ok so bear with me, because some people on these forms don’t think newbies should ask questions. On the holding tank display inside my rig, 2004 Forrest river sunseeker, there is a pump toggle switch ??? Is this for simply pumping out the tanks, gray, black? Is it for all of them ? I know on a boat I used to own there was a masarator pump. What does your he rv pump, pump ? An when to use it.

Most likely your water pump... used to provide water pressure from the fresh tank to your water outlets (sink, shower, toilet, etc).

Note that the tank display also displays FRESH water tank level, too (as well as battery level).

I'm not familiar with your specific model but initially I'd think that it's for the water pump which is needed when you're not connected to city water. (Of course you need to have water in your fresh water tank as well.)

Agree that this would operate your water pump.

A small thing, but that's a rocker switch, not a toggle.

While some RVs have macerator pumps for the black and grey tanks, a switch to operate a macerator should be located where you could monitor progress...near the dump connection.

On those led monitors...they are notoriously inaccurate... especially the black tank monitor. Press and hold the labeled "button" and you get a crude reading of the status of your fresh water, grey water, and black water tanks... and your battery. But all that stuff in the black tank tends to confuse the primitive sensors. Thorough cleaning of the black tank helps. Since the other tanks are cleaner water, the sensors work better.

If in doubt, you can turn off the water supply and look down the toilet to check the status of your black tank.

Seems like you have received or read some less than kind replies on the forums, Steve. I'm sorry you have experienced that. My experience has been different. Hopefully the fast, accurate, informative replies you have received to this post will give you a better feeling about the folks here. I didn't notice any snarkiness or sarcasm in the replies. There's lots of good, helpful people on the forums and I've benefited greatly in the 4 years I've been a member. Cheers!

Thanks Mark. Not on this post but some in the past got some not so welcoming comments, actually just from 1 person, but you know what they say there always 1 in every crowd ��

Won’t find many of those here Steve. Most of us remember what it was like not knowing things when we started this hobby.

This site has been great for the knowledge and willingness to share to those that are still learning.

There was a discussion about testing the pressure relief valve on the water heater. I asked how simply lifting the latch was testing the valve because it did not test at what pressure the valve would open. Someone else replied it wasn't checking the calibration of the valve, only that it was not frozen and capable of being opened. Aha moment there! It may have seemed like a dumb question but the simple answer simply told me what the purpose of that test was.
