I installed one of these the other day. Got the camper out of winter storage and installed it prior to sanitizing the system. Here's my findings and notes:
- It was a PITA to install. But only because of where my water pump was located and how tight it was for space. Other than the tight area and interference, installation was a breeze and they provided everything needed except for tools.
- Be sure to have a magnifying glass around to see the tiny dip switches and to set them properly. I may or may not have had to use one... 🙄
- Be sure to set it for a tankless or tank water heater based on your rig. The overall programming is a bit of a pain and you have to follow the steps carefully, but there are YouTube videos to help as well as instructions. I found the videos most helpful.
- I was going to install an accumulator tank with silencing kit, but after researching this, I decided to try it. Ultimately, it isn't that much more money than an accumulator tank and a silencing kit, and I liked the idea of some of the other features it provided such as the timers to prevent the pump from running too long (in the event of a leak), run dry prevention, and over cycling.
- It makes a HUGE difference on sound. It will not make your pump dead silent, but it prevents the water hammer, the pulsing, and most of the cycling. It really did make a huge difference. I was impressed, and that ain't easy.
- It did not stop the cycling completely. The pump still cycles when a faucet is on a very low trickle, but it is less often and less noticeable.
- I did not purchase this for any energy savings. Jared Gillis claimed that it saved about 0.5 amps so that may interest you, but I did not buy and install for power savings.
- It's a simple piece of technology and technology is great until it fails. But if I needed to remove it from the system in the middle of a trip I could do so fairly easy with minimal tools.
- I haven't used it for very long, but for me I'd call this a winner for the results in performance, price, and time to install. But long term will tell more of the story.
