I have an auto filler on a house I purchased and have noticed a rusty colored stain where the outlet of the auto filler goes into the pool. Looked inside the autofill there is a large gap where the water can slosh around and come into contact with the sand and dirt. This in turn is causing the water to get rusty and then getting rust into the pool. No good.
My questions is, on the back of the autofill there seems to be some type of "vent" or something. It's a white plastic piece with some slits in there? Also, am I right in assuming that the top cover should fit and overlap the actual autofill "container" under the decking? There should't be a gap where the water can mix with the dirt?
Also, is there some type of overflow pipe which should be installed? I don't think this thing was ever installed right.
We have a paver deck, so it shouldn't be too bad having to get in there and replace it. I'm thinking about just extending the pipe for the filler and putting the autofill out of the desk and in the neighboring flower bed. It's all covered anyways.
I will try and take some pictures in the morning and update the thread.
