We had an excellent experience with them. He has been out here before. He came out and checked the system. He identified the leak. He told us where it was coming from. It was from our automatic pool filler. We went to the pool guy and replaced that. He charged us nothing. He was here a good hour tracing the leak. He has always done a very, very, excellent job for us. It was really important, and he came right away. Of course it was on a Saturday. We told him the city had knocked on our door, and all of a sudden it was a huge leak. I was glad that they did that, but I was quite concerned. He came within a half hour; very rapidly. We were very pleased. It was so nice because it was costing us quite a bit of money with the water, especially with the drought. Because it was outside, we hadn't heard or seen anything. He was really invaluable in finding that and helping us with it. He was just great and very helpful. He arrived right when he said. Of course I would use him again. In fact, we had to do some searching to find him. We remembered he had a dog in his ad, but we couldn't find the card. We had to search the internet for a plumber with a dog in it.
