Multi Water Level Sensor reading is dropping.

[Sacohen]

Are you talking about the orange piece on top?

[rimai]

Yes.
Is it possible to swap the one you are using with the single channel?

[Sacohen]

I was thinking of doing that.
I'll try it this weekend.

[Sacohen]

I put the tubing, PVC adapter and pipe that was on WL1 on the single and Visa-versa.
now the single is dropping.

It went from 100% to 94% today and the ATO has not run, so no water came out of the reservoir.

So the problem seems to be with either the tubing, the adapter or the pipe.
The coupling that the adapter is in was glued into place with PVC cement.
So it could be the tubing.
I don't remember if you answered, but will putting a longer piece of tubing cause any problems?
I wouldn't think so as long as it was calibrated with the length of tube.

I'm using a 10' piece of 1/4 in. OD x .170 in. ID Clear PVC Tubing.
What are the dimension of the tube you supply with the adapter?
The tube fits tight into the adapter and over the nipple on the sensor.

In this case, can you please use some silicone or more pvc cement over the existing seal of the orange piece and the 1/2 coupler and also on top of the pvc coupler and the pcv pipe?
Maybe there is a leak in there somewhere you can't see.
I doubt the problem is on the tubing or length of it.

[Sacohen]

I wouldn't think do either.
Ok. I'll try silicone.

[Sacohen]

That seems to have done it.
Sealed it with hot glue.
Recalibrated and it's been at 99% since about 6pm.

[Sacohen]

It's happening again.
The last time I filled the ATO resivour the ML senosr #1 worked fine.

When it got down to 1% I filled up the resivior and it's now reading 81% when visually it only looks like 95%.

No changes have been made to the setup.

I've had that happen on occasion
