We had a terrific encounter with GMP. I called because my elderly mother pipes leaked. . .again. They gave us a fantastic cost to replace the plumbing. While they were there, they discovered that we didn't have a working pressure relief valve to the water pressure. They fixed that. . .along with everything. They told my mom. . .that hadn't worked in years. . .because it may start to do the job. . .IT DID! Needless to saywe were thrilled that they went beyond and above. They have been on time, friendly and professional.

Larry came out to inspect the water pressure in our house. He was very nice and useful. He explained precisely what he thought the issue was and did not force us into using them to fix it.
