Best Halo Water Filtration System in Irvine CA

The pipe behind the drywall in my house was leaking so I've reached out to them for repair. They told me if the tech come right now, it'd be consider an emergency and will be $189 fee. I asked them what's other availability, and they didn't respond, and just said tech is available right now. I figure sure why not, they are eager to make the fee, and I am eager to get it fix. The tech arrived, took a few look and told me they can't do anything or even figure out where the problem is, because the leaking is behind the wall, and they need to me to hire someone to test for asbestos before they can open up the wall. They gave me a bunch of analysis, which is essentially what I've already told them. I was charged for a $189 fee even though they've done absolutely nothing except showing up. I am fine paying for the emergency fee under the premise that they can do something that I couldn't myself. If they can't diagnose pipe behind drywall, then this whole thing wouldn't have happen had they simply asked me the age of my home, and listen to me for the fact that leaking is behind the wall. I ended up hired somebody who actually know what they are doing. In addition, I had them installed Irrigation Plastic Control Valve in Feb, and the thing busted and leak by August. Sure, they fixed it under warranty for me, but the whole thing costed me over $3500, and I question their work's longevity. I will change my primary plumber to somebody more capable since this whole incident.
