It will extend the service life of any septic air pump by eliminating harmful aeration system back pressure. But what is back pressure? Have you ever noticed that no matter what replacement septic air pump you buy, it seems to last less and less time? This is because over time sludge buildup at the bottom of the sewage treatment plant begins to clog the quarter inch holes of the ½” PVC aeration pipe. The same volume of air being pushed through fewer holes create excessive back pressure at the air pump and this causes the aerator to overheat and results in premature air pump failure. My patent pending septic air pump protection valve will vent off all harmful back pressure and allow your aerator pump to give you maximum service life. So, protect your investment and get this indispensable tool! DIRECTIONS ON HOW TO EMPLOY THE SEPTIC AERATION SYSTEM PROTECTION VALVE (REMEMBER THAT THIS VALVE IS TO TEST AND PROTECT YOUR PUMP AGAINST HARMFUL BACK PRESSURE DUE TO AIRLINE OBSTRUCTION UNTIL SUCH TIME AS THE OBSTRUCTION CAN BE REMOVED OR REPAIRED. IT WAS NEVER INTENDED TO REMAIN CONECTED FULLTIME, IN THE OUTDOOR ENVIRONMENT) 1. Connect the protection valve between the air pump and the existing pvc aeration line. 2. Turn on the air pump and note whether air is being vented off by the safety valve. a. If not, your aeration system is free of harmful back pressure and your air pump will give you maximum service life. b. If air is being vented off, it is clear that you need to remove your aeration pipe from inside your sewage treatment plant or install my flexible replacement aeration pipe in its place. i. In this case, remember that your air pump is in no immediate danger…it is in not being damaged as the back pressure is being limited by the safety valve. Not only that, your treatment plant is still being aerated; just not at the air pump’s rated liters/min. ii. So no hurry, the safety valve is in charge. Just do the fix on your aeration line when you have time.

It’s a very good idea to have this on your air pump. However, the materials in the pressure relief device does not hold up to the outdoor environment. The small O ring and check seal dry rots and the compressed air is then discharged . Then the air volume is to low for agitation within the tank. My first one lasted about 6 months and the seller made it good with a replacement. The 2nd lasted almost a year then failed, I then just removed and used a 1/2” pvc coupling and nipple. Again this is an excellent idea, but must find better materials . On the replacement I used a protective cover on it and it did last about 6 months longer. The seller was very accommodating and Im sure he will improve his product because it’s a much needed device in protecting that expensive air pump.

Lasted a few months then blew guts out instead of popping and resetting

This item was purchased for the protection provided to our septic air pump. It installed easily and allows the pump to function normally. It's effectiveness won't be known unless there's a problem with the system and hopefully it won't be tested, but it's a small investment to protect the pump.

For what this is, it is overpriced but it appears to be the only safety pressure relief valve of this kind. Given that some pumps are way over sensitive to back pressure, if you have one of those pumps, you need one of these valves. The way it is shown installed would not work on my Blue Diamond pump and Blue Diamond was no help finding a fitting that would work. Instead I reversed it, used the 3/8 hose fitting that came with my pump and connected to a 3/8 hose fitting into a 1/2" pvc adapter then used some 1/2" pvc pipe to join with the valve.
