The Pool Auto-Fill is an automatic pool water leveler, designed to maintain the optimum water level in pools, spas and fountains. They are more commonly used in the warmer regions of these United States, in dry and arid regions that have to add frequent make-up water.
Automatic pool fillers have been around for a long time, and gained popularity in the 1970’s across southern sunbelt pools. The first AutoFill devices were made by American Products and PoolMiser, and the poolside canister design has not changed all that much, except for recently, when Pentair introduced model T40F, with a familiar FluidMaster style of float valve, used in most common toilet tanks. The Brass valve and float model T40B, is also available from Pentair.
Old Style and New Style Auto-Fill Valves
The two auto-fill valve designs are technically not interchangeable, because the Brass Valve and Float connects to the incoming water supply near the top of the canister (or automatic filler bucket), and the vertically oriented FluidMaster AutoFill Valve, connects to the water supply at the bottom center of the canister (see image). Many Brass Valve canisters also have a bottom center port however, and in such cases, the new style valve can be installed if you also move the water supply line from the upper-side to the center-bottom of the canister.
Replacing the entire unit with the newer style is also possible, however the task can be arduous. Excavate around the cylinder carefully and gently cut the equalizer line and the water supply line. After breaking free the canister from the pool wall or its concrete encasement, the new canister is placed level with the pool, and pinned to the pool wall or otherwise secured to prevent movement or settling. After reconnecting the equalizer and water supply line, pressure test to confirm no leaks, before backfilling and tamping the area, or pouring new concrete. It may be simpler to fill it full of concrete, or otherwise and seal it off, and install a new wireless autofill in your pool filter area.
