I have a 16,000 gallon in-ground vinyl pool with a mesh cover. When it
was closed, the pool company had me drain the pool down to near the
bottom of the skimmer opening (about 12-18 inches below the edge of the
pool). Over the past couple months, we have had a whole lot of rain,
and the pool is filling up - to the point where the water level is
above where it would normally be when we use it. The mesh cover was
actually touching the water in the middle. This past weekend, I
siphoned about 1.5 inches of water out of it with a garden hose to help
a bit, but it's supposed to rain all week again. I live in Michigan if
that's relavant.

Is it a problem if it fills up over the cover (and possibly to the edge
of the pool itself)? Water would be over the mesh cover at that point.
Or should I siphon more water out of it to get the water level down to
where it should be? My only concern with siphoning is I am also
siphoning out a percentage of the chemicals I put in the pool to
winterize it. I could always add some shock too, I suppose, if that
would help.

Any advice would be appreciated!

Pool + Michigan = ?

Not a big pool guy, but if the purpose of lowering the level was to
drain the pipes so they won't freeze and crack, you'll have to lower
the level and re-drain the pipes.

For the chemicals, whatever dilution there will be has already
occurred, so draining won't change the chemical levels/balance.

Don't know if you need to add more, though.

Thanks for your reply.

When they winterized it, they blew out all the pipes with compressed
air and capped them. The (now capped) water jets were all well below
the water level at the time, so I'm not concerned about that.

As far as chemistry, I'm more worried about diluting what's there by
removing water. When you remove some water, you are also removing some
chemicals that were in that water. When it rains, the water level
rises, but the chemistry level is diluted from what was there
previously since water with chemicals in it was removed. It may not be
enough to matter, though. Or as I mentioned, I could add a bag of
shock when draining it.

Or if having the pool absolutely full isn't a problem with the mesh
cover slightly under the water, then I'll leave everything as it is.

Can't you call the company that performed the winterizing and ask them?
