"The Plumbing Authority got back to me right away once I connected with them on Angi. We agreed on a date and time for them to come to my house and they were there exactly when they said they would be. Mikhail was very polite and professional and didn't try and "upsell" me anything. He kept the area that he was working in clean and when he left you wouldn't have known he was ever there except for the leak problem had been fixed. He completed the work very timely.

"When the plumber got to my home and he went under the house to look at the water lake that I had he took pictures. Of what needed to be done? He said, I needed a new water pressure valve to stop the water lake. Tell me it cost $300 for water pressure valve when it doesn't. And they're not needed a water space, it plugged off and one replaced. Charged me $900. He left the underpinning down. Did not put it back like it was. The water lake is there. I don't have no hot water. Haven't had no hot water since the day. He'd done it, call them, come back out. Did not fix it Got in the truck and left. Never said a word. I try to live on $811 a month. They took every penny I had and did not fix it. So no I would never use them again. And if you're a single woman, don't call them. Out, because they we'll rip you off.
