I am considering purchasing the Levolor K1100 auto fill system, and have questions regarding the installation. From reading the manual I understand that there are two basic install methods:
1.)Using a static standpipe into which a sensor sits vertically, or
2.)Using a “remote” sensor mounted onto the inside of a skimmer.
I am leaning towards the second option because I feel that having a static pipe without much water flow and exposure to fresh sanitizer is going to potentially become a “breeding ground” for undesirable things. In my installation the pipe would be 20-25’ long over to the equipment pad, and I would expect nearly zero water flow in the pipe except for some wave action...
If the second method is used, how does the sensor typically get into the skimmer? Do you run a separate conduit into the skimmer body and then seal it somehow? How would one seal this fitting? Also, how is the sensor bonded to meet electrical code as it becomes a metallic object within the water zone?
Maybe I would be better off with a "typical" auto-fill system? I've read on a couple of posts that you can connect the auto-fill unit to an unused skimmer port - How much does the water level in a skimmer change when the pump is actually drawing from it (I know there are many variables - but imagine 2 skimmers on an 18x36 with a 1.5hp pump). Would the water level in the skimmer drop by say 1/2"? Then the Autofill would try and compensate for this... I guess this might be OK, because when the pump cycles off, the level will rise slightly higher than it originally was (~1/2") - and this shouldn't be an issue - right??
Again, would there would be very little "flow" in this pipe that connects the autofill to the skimmer, although it could be much shorter (AKA a breeding ground for algae and bacteria)?
Thanks for your input...
