On my pool they plumbed in a fill line, but it's by the skimmer, it's by
If you don't have that, you can plumb something in over by the suction
side of the pump if you don't want to use a hose.

There is no overflow valve plumbed into the pool. I haven't seen them on
any pools out here.
Before we re-did the pool and replaced the concrete, there was access to
the pool light wiring from the concrete deck, but the code changed and
now it would be really hard to get to the light wiring conduit to sense
the water level.

I looked for these myself. One problem is how to mount them in the pool,
the waves being one problem, and just kids kicking it and breaking it
About the only place it can fit is in one of the four corners of the pool,
bolted to the gunnite.
You wouldn't put such a valve in the main pool itself, however you
want to locate it somewhere connected to that body of water where it
would not be subject to wave action when the pool is being used and
automatic filling of the pool would create waves itself which might
You would want to build a chamber of some sort, like a sump pit,
connected to the pool with a large diameter pipe... Within that
you would install the float valve which would regulate the water level
pool... Since a body of water always levels itself out this would
long as the water inlet where the water is to be added is not within
chamber and was located far enough away so that any motion or
created by the addition of the water would not effect the operation of
float valve... The idea of a body of water always leveling itself out
water levels are used in construction on some projects where a laser
is overkill or not an affordable option...
Yeah, I'm only looking for something for when I'm on vacation, though
still I'd like it to be not a total kludge. A float valve is a good
idea. Not as elegant as the probes and relay, but a lot cheaper.
In addition to the other suggestions...
Visit the local ag supply store (Tractor Supply Store, Grange, etc)
Get a 'stock tank float'. Purpose built to do exactly what you want.
How to mount it will be up to you. It just needs to be clamped to
something (comes with the clamp).
Scavage a level control valve from a washing machine someone throws out. Attach
a plastic tube to it and run the tube into the pool. Adjust the level of the
bottom of the tube until it switches at the desired water level. Attach the
water control valve to its power source through the switch on the level switch.
Use a double throw relay to reverse the switching if the level switch doesn't
have double throw connections.
A friend of mine has a spendy one that's all plastic, and a real POS. It is
forever falling over, and then the water runs continuously. It is fed by a
simple garden hose. A McGyver type guy could make one simple enough. The
problem is finding a place in the pool where it is protected from rowdy
kids, and having it weighted so that it won't fall over and free flow. I
don't think either problem is insurmountable. As for a way to open the
drain diverter, that would take more machinery, and that could be prone to
failure or mistake, in which case you might just lose several thousand
gallons of water. I'd consider a sensor just like the one that senses low
level, but have that sensor activate a pump to drain the water, and kick off
once the water level is down. If one is an electric type person, a low
voltage sensor should not be difficult, and that can run to either an
actuator to fill, or to a pump to drain.
