"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

Dutton Plumbing, Cooling, Heating & Electrical runs out of two locations, one in Simi Valley and one in Sylmar. We’ve been working out of this valley since 1987. From those two shops, we cover Ventura County, the San Fernando Valley, Santa Clarita, and Northern Los Angeles County. That’s plumbing, drain and sewer, water heaters, HVAC, and electrical, all handled by the same crews. Nearly four decades in the same region adds up. Our crews have been inside enough houses out here to recognize what a given neighborhood tends to do before they open anything up. Post-war ranch homes behave one way, newer builds behave differently, and we’ve seen it all.

The original installation was in the end of Dec. 2012. The installer was good. He brought his son, who started going through my things, as I had just moved in. When I told him to not go through my things, he went out the garage. Later that day I found food missing out of my garage freezer. I called the salesman about this and he made right with it and reimbursed me.

 I had to have the controller changed as it stopped softening my water and it was leaking. It was very difficult to get in touch with anyone at customer service and then when I did, it took them a long time to get out and repair it. I was told to turn my water off until they could get out here. Really? Be without any water for a couple days?

 Now, I find the system they installed under my kitchen sink has been leaking. It looks like it's been leaking for a while. It appears my cabinet bottom is slightly warped from this. I live in a new home. It was build a year ago and I moved in. I will have to have it checked for mold now as well. But I tried calling AmeriTek today, and again, I'm told the Tech would call me. It's the end of the day and no call. I called them back for the 4th time and they said the Tech would call me sometime tomorrow. No time given. Several customer service people I spoke with said they would call me back in a few minutes. I gave them over 30 minutes to call me back. They never did. When I called,  I was asked if people called me back, I said no. They actually asked me if I wanted the yearly service (which I was never told about). That they would check the whole system and change filters. I asked what the charge would be. They told me $150.00. With the customer service I have experienced with this company, I don't think I will give them more of my business. I will call Puronics themselves and get an estimate for that.   I think it's time for me to call a plumber and send AmeriTek the bill.

I'm not saying anything bad about Puronics. This is just one Company that installs it.
