Frequently Asked Questions
Do I need a plumber to install an automatic pool filler?
If you choose a deck mount unit, you can usually handle the installation yourself using standard garden hose connections. It is a straightforward process that involves placing the unit on the deck and connecting your supply line. However, an in-wall unit requires significant plumbing and masonry work. You will need to tie the unit into your home water supply, which often necessitates a licensed plumber. Do not attempt in-wall installation unless you have experience with pool hydraulics.
Will these fillers increase my water bill significantly?
An automatic filler only adds the water lost to evaporation or splashing. Because it replaces what was already there, you should not see a sudden spike in your costs. In fact, it saves money by preventing your pool pump from running dry, which is an expensive repair. The only time you will notice a higher bill is if you have a hidden leak. If the filler runs constantly, it is telling you that your pool is losing water faster than it should. Use the filler as a diagnostic tool to spot structural issues early.
Can I use an automatic filler with a saltwater pool?
Yes, but you must select materials carefully. Salt is highly corrosive, so you should prioritize 316 stainless steel or specialized plastic components. Standard brass or low-grade metal valves will degrade rapidly in a saline environment. Always check the product label for saltwater compatibility. Many manufacturers explicitly state whether their parts can withstand the chemical balance of a salt chlorine generator. If in doubt, stick to high quality plastics that are immune to salt damage.
How often do these devices need maintenance?
You should inspect your filler at least once a month during the swimming season. Check for mineral buildup on the float or the sensor, as scale can prevent the valve from closing properly. A quick scrub with a mild cleaning solution keeps everything moving smoothly. If you use a mechanical float, keep an eye on the sealing washer. These rubber parts harden over time and can lose their seal. Replacing a small washer is a cheap way to prevent a major leak.
What happens if the power goes out?
Mechanical float valves do not require power, so they will continue to function normally during an outage. They are essentially gravity and buoyancy based, making them very reliable when the grid fails. Electronic units often have a battery backup or a fail-safe mode that closes the valve when power is lost. If your system relies on an electric solenoid, verify that it is "normally closed." This ensures that the water shuts off automatically if the power supply is interrupted.
