    Auto-fill valve and water level adjustment

    Had a an autofill valve plumbed into our new IG pool during build. The PB used a Poolmiser PM-101; uses a conventional water level adjustment like a Fluidmaster toilet fill valve.

    Water Leveler - Poolmiser Automatic Water Leveler - PM-101

    Had it connected to our irrigation supply line last week with a master shutoff valve. The AF supply is after the RPZ (backflow preventer).

    The PM-101 seems pretty simple. Has an overflow drain (the PB didn't connect this anywhere) and a pipe to the pool. Will likely cap the overflow inside the AF so it doesn't drain under our deck. But where does the other pipe connect typically? To a return? I can't see an extra pipe in pool that would seem to be coming from the autofill.

    Yet when I remove the cover from Poolmiser, it always has water in it, so it seems to be getting water from the pool somewhere.

    As you said the pipe to the pool is on it's own, typically directly inline with the leveler. Usually the finish it with a return fitting matching the others in pool

    Ok. Thanks. I believe I've found it, but it's underwater in the shallow end of the pool. In other words, the autofill line is below the water level rather that at or above the surface. Will it still work?

    Yes, it's just squirting water into the pool.
