Automatic Air Relief Safety Valve AR300

the unit does work to discharge air but on low pump speeds, it probably spits out more water than what goes to the pool. not going to work for my application.

I had a vacuum in the system when off, The old valve would cause the filter valve to burp all night long and keep me up at night. Only if I released the valve after the pump was off and allowed the filter to drain would that solve the problem for the night.The inventor of the safety valve told me that at startup-and-vacuum release the safety valve would discharge a bit of water which only lasts for less than a second. If you have a concrete deck or have the valve pointed at other equipment this might affect you.I just pointed the safety valves hose so it would points away from other equipment and the area outside my pad is crushed rock so the water can drain away. Good product! Just point the valve away from other equipment and expect the discharge.

Read the fine print. You will be charged to return an already overpriced item.

I was a fool and did not listen to the negative reviews. I got the product, a piece was missing. Three EMAILS went unanswered. I finally found a replacement in Rural King that fit. Got it hooked up and the water pouring out of the discharge hose NEVER stopped. Turn off the filter to stop the flood. DO NOT BUY THIS. IT does not work!!

I have been waiting for someone to develop a reliable automatic air release valve for my pool filter for years. I installed this valve in about two minutes and it does exactly what I need it to do. It automatically purges air from my pool filter tank at startup instead of having to do it manually.

Does what it says. I have had some sort of air leaking in my pool system. The air gap was causing my flow sensor to show no flow and therefore stopping my salt cell system from genrating. This did the trick. The one thing I wish it didn't do is, it lets the system drain down. So acts as a vent when the pressure is zero, then releases the air when it starts up.

Horrible bought two for two different filters. neither sealed well and let out a constant trickle of water. enough to lose hundreds of gallons a day!!

Excellent product does the job !!!
