All I gotta say is everything being said is common. Bill never answers phone calls. His warranty is frankly worthless. I would have thought he had changed his ways but it is the same crap it has always been. As for the backfeed I had the same problem and he mentioned I won't need a check valve.
The reports of back flowing had me wondering. I just put my ACR into service and had no check valve on it. I just did a test, turned off the pump and controller on the ACR and pulled my feed line off (the equivalent of the feed pump stopping). I got an immediate stream of water back flowing out of the ACR feed line. This surprised me as I was thinking the ACR being sealed, along with the effluent valve being closed, would prevent the back flow. After thinking about it, the ACR is under pressure, 10 PSI to be exact, so the feed line will definitely back flow as the pressure normalizes with atmospheric. It will probably even back flow after that as air bubbles work their way along the feed line to replace water already in the unit. I installed a check valve to prevent this from occurring.
As for dealing with Bill, I am just about to send in a deposit on a custom sump valued at several ACR units. I do this after waiting 11 months for my ACR unit to ship. The original estimate was 2 months. I also experienced lots of trouble with contact and when I did, my unit was just about to ship,
for months. Towards the end, I was so frustrated, I started sending very un-Canadian like emails (no please and thank you's :mad: ). When the unit arrived, I realized it was worth the wait. He really does do an excellent job machining the purpose made parts for his equipment. That is why I am willing to use him for my custom sump as I know the outcome should be worth any possible aggravation in the process.
Besides, he assures me they have got better at shipping things in a timely fashion. I guess I will just have to wait and see.
