Review on 🔒 Wayne WSS30VN: Upgraded Combination 1/2 HP and 12-Volt Battery Back Up System in Black - Efficient Solution for Added Security and Reliability by Chris Norman

I hooked up this unit today and made some observations which I hope will help some of you: For this unit I have a large Vmaxtanks 120ah AGM Marine battery with me ordered this one and this one fits perfectly in the plastic case that comes with the pump. The box measures 14"L x 9"H x 9"D. Wiring is very easy. There are 3 very different connectors that you cannot miswire. A combination of two pumps does not require two. No big deal. I connected a 12v backup pump to a new 120v Wayne 3/4hp primary with a PVC Y fitting and then connected to an outlet pipe via a quick connect screw on the stock fitting. It's a 2 inch PVC pipe so no problem with flow either. I used PVC tubing for all connections except one. Since the 2 pumps had to fit snugly I had to rotate them a bit so I used a rubber fitting (Fernco) on the backup pump. I also did NOT reverse install valves 3' up the outlet tube as suggested in the instructions. Setting the check valves this high allows 3 feet of water to flow back into the pit every time the pump stops, and this will cause the valve to knock. I've used 2 o Lowes sibling valves threaded right on the bottom the valves. They screw directly into the base of the pump (I used silicone grease to lubricate the threads to keep them from sticking). The outlet side of the valve fits a 1 1/2 PVC fitting, but here I used a Fernco rubber fitting. So for maintenance or if one of the pumps fails I can just unscrew this fitting instead of cutting the PVC pipe. After everything was glued and assembled, I lowered the unit into the cesspool, but the pumps didn't sit on the bottom. My sump is 25 inches deep and 18 inches wide, but due to the Fernco fitting I was able to rotate the backup pump a bit and they both bottomed out nicely. Product Description): The backup pump float switch is not typical. It just turns on the timer. The pump will then run for 20 seconds and this cannot be changed. This can be a problem if your hole isn't deep enough or if the float isn't set high enough. If any of these situations apply, the pump will drain the pit and continue running until 20 seconds have elapsed. AWAY; THERE SHOULD BE SOME ADJUSTMENT ON THE PCB FOR THIS! I'm an electronics genius, so maybe I'll take a look at what resistor is causing the 20 second run time and change it to an adjustable one. (Any help with that Wayne)? Secondly; I have a small electric FM radio on my desk and the circuit board in the battery cover completely covers it. I had to put the battery box on the floor behind me to hear my radio! AWAY; USE SOME SHIELDING ON THE CIRCUIT AND WIRING! Finally that annoying alarm clock! It turns itself off after 20 seconds, but it needs a volume control! As a connoisseur of electronics, I solved the problem without causing any damage. I removed the 3 small screws holding the circuit board to the cover and found the little demon. There is a tiny hole in the gray plastic PCB speaker cover. I GENTLY place a small piece of cloth in the hole and it calms him down nicely. DO NOT insert the cloth more than 1/16 inch or you will damage the tiny speaker. Another thing (not a complaint) is the charger itself. This is a heavy unit. It doesn't stay connected to most outlets. I ended up using a small extension cord and laying it on the floor and it works great. Now that all the demons are gone, this is a really good device. To test the backup pump, I simply left the 120 volt main pump unplugged and figured out where to place the float switch, then let the pit fill. The backup pump ran for exactly 20 seconds, but the pit was empty in 18 seconds. Not a bad guess, right? I then connected the main pump and it worked perfectly and was very quiet! Hope this helps someone.
