AutoFill
AutoFill valves are used to automatically maintain the optimum water level in pools, spa, and fountains. Basic components of an autofill are a sensor for the water level connected to a valve that lets fill water in when the pool, spa or fountain water level is low. The autofill has an equalizer pipe connected to the pool, spa or fountain and may have an overflow pipe.
The autofill is often a canister by the pool and has a round lid that looks like a skimmer.
Autofills use one of three types of water level sensors:
- Float valve
- FludiMaster valve
- Electronic sensor
