    Is this a flow sensor?

    Hey folks!

    Please note the 2 photos below. I assume this a flow sensor. As you can see from the second pic, water spews from it when the pump is on.

    I opened it. It still has a small rubber o-ring and I tightened the clamp. But it still leaks. I think this is a part of a leak issue I've been dealing with all summer.

    Is there an epoxy or sealant I should use on it? Do I need to replace it?

    Thanks!

    It looks like a flow sensor, but Ive never seen one where the pvc piple was drilled and it epoxied in.
    Im sure there are lots of things around pools that Ive never seen though.

    Usually, there is conduit fitting with a "T" on it which the flow fits into.

    Do you have an automation system that monitors temperature? It could be a temperature sensor. My temperature sensors from the EasyTouch system look like that.

    As Robbie mentioned, that's a temp sensor. You can shut the system down and remove it from the plumbing and either find an o-ring that fits or dry it well and use a bead of silicone caulking to seal it back in the line. If you go the caulking route, you'll need to wait until the next day to turn the system back on.

    Hi Newsguy. You have a Jandy temp sensor. A pool store should stock that oring. I've never had any sealants work. If the nee oring doesn't solve the leak, sometimes the pipe is melted so that the sensor hole is out of round. At that point, the only fix is to cut out that section of pipe, replace it, and drill a new hole for the sensor.

    I assume you've tried tightening the **** out of that hose clamp to no avail? It might slow the leak down but, yeah, you should get a new o-ring and get some silicone lube with it while you're at it.
