Frequently Asked Questions
Do I need a professional plumber to install an automatic pool filler?
Many surface-mounted models are plug-and-play devices that connect directly to a garden hose. If you choose a built-in unit, you will definitely need a professional. Improper plumbing can cause leaks behind the coping, which lead to expensive structural repairs.
Will these fillers affect my pool chemistry?
They introduce fresh water, which can slightly dilute your chemicals. This is usually a minor issue unless you have a massive leak or a very small pool. Just monitor your pH levels after heavy evaporation cycles.
Can I leave the filler connected during winter?
Never leave a water-filled device connected if you live in a climate with freezing temperatures. Ice expansion will crack the valve housing or the supply line. Always disconnect and drain the unit before the first frost arrives.
How do I adjust the water level settings?
Most manual floats use a threaded rod or a thumb screw to change the height. You simply twist the float upward or downward to match your desired water line. It is a straightforward process that takes less than a minute.
Are automatic fillers expensive to operate?
The cost is simply the price of the water you use. Because these devices stop filling as soon as the water touches the sensor, they are much more efficient than manually topping off your pool with a hose. You will likely save money by preventing water waste from forgetting to turn the spigot off.
