## Description

PROTECT YOUR SEPTIC AIR PUMP/AERATOR INVESTMENT!!! This is the only septic air pump on the market with a safety valve for dangerous back pressure. It will extend the service life of this already dependable 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 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.

Review: Great product - Works great, will buy again. We have had no issues with it on our septic system.
Review: Working Well - I'm using the pump to power a pond aeration system (an application that, for some reason, apparently voids the warranty). It's been in operation for about two weeks and so far is working well. Initially, I had a problem with the pump overheating--caused by the diffuser in the pond getting plugged with algae. This caused the pump to shut itself off...to protect itself I guess. I solved this problem with a larger diffuser that floats off the bottom to avoid getting plugged, and all has been well since then. Fingers crossed. And the pond is looking better--clearer water with less algae buildup--now that it is being oxygenated.

### ⭐⭐⭐ Disappointed in product but love the company!
*by T***K on August 9, 2020*

I purchased this pump 15 months ago to aerator my pond. It worked great until 2 months when it just died. My hubby has been dealing with the company & they're awesome. Great communication, which is hard to find these days. They sent us a rebuild kit but that didn’t work either. Now we have to purchase another one pump & it’s barely been a year.
