We have used Parley's PPM a bunch of times and they have always done well. Most recently, they helped me with a faucet. I had a faucet that was spitting out what I though was hard water. When they came out, they told us we needed a new faucet, which I then had my grandson put in. But once installed, the new faucet had no hot water pressure. Their plumber came back out and he found and removed pieces of plastic, which fixed the problem. I had them come out a total of three times for this problem and they actually gave me a discount. Overall, they have been very good.
