Frequently Asked Questions
Do I really need an automatic pool filler if I have a garden hose?
You technically do not, but you do need to remember to turn the hose off before you go to bed. An automatic filler acts like a safety net for your pool level, preventing the water from dropping low enough to damage your pump. It saves you from the constant monitoring required to keep your pool at the perfect level.
Will an automatic filler raise my water bill significantly?
It only replaces the water lost to evaporation or splash-out, so it should not cause a massive spike in costs. If you notice your bill skyrocketing, you likely have a hidden leak in your pool liner or plumbing. The filler is just doing its job by keeping the level consistent, even if that water is escaping elsewhere.
Can I install these myself or do I need a professional?
Most deck-mount units are a simple DIY project that takes less than twenty minutes. If you choose a plumbed-in model, you might need some basic plumbing skills or a local handyman to handle the connection to your water line. Always ensure you follow the manufacturer instructions regarding backflow prevention to keep your water supply safe.
What happens if the filler gets stuck in the open position?
This is why you should look for a model with an overflow drain or a high-quality shut-off valve. Most modern units include a secondary shut-off feature or a fail-safe mechanism to prevent the pool from overflowing. Regularly checking the float ensures that mineral buildup does not cause the valve to stick while you are away.
How often should I clean or maintain the filler?
Give the unit a quick inspection every time you clean your pool filter. You should wipe away any calcium deposits or debris that might interfere with the float arm movement. A little bit of preventative maintenance twice a season keeps the valve operating smoothly for years.
