Trick to make water level sensor quit leaking

[dedvalson]

Hi,

I have the multi channel water level expansion. I have tried repeatedly to get stable results but always got slow air leaks which would cause the values to slowly drift to zero over a period of several weeks.

All of my joints were sealed with normal PVC pipe blue glue but the junction between the flexible airline tubing and the orange fitting always leaked.

I finally found a solution that worked. I used thin Cyanoacrylate glue (super glue) and poured a small puddle of it in the orange adapter where it joins the airline tubing. Now everything is rock solid. Since the glue is so thin (like water) it actually filled in between the tubing and the adapter.

It was interesting to note that when I put the CA glue in at first, I actually saw bubbles coming up through the glue from the slow air leak. I had to remove the pipe from the water so there was no air pressure on the joint while the glue dried.

Great idea! I've been using epoxy but I think this might even be better.

i used silicone

I've used silicone and hot glue. Both have worked fine for me.
