"Western Rooter to the rescue again! I had a small underground leak which appeared to be due to a bad sprinkler valve. A sprinkler repair company determined that it was not a bad sprinkler valve and thought it was due to a leak in the main water line. Daniel and Alex dug down to find that the leak was coming from a very old (at least 36 years) broken pvc line. After much testing and head scratching to try to figure out where the water was coming from, they decided to "chase the pipe." After much digging, they found that the very old broken pvc pipe was hooked up to a sprinkler valve that was buried 18 inches underground that had not been capped--only turned off. Roots from a nearby tree had opened the valve which caused the leak--crazy! The current sprinkler system has been the same one since we moved into the house in 1988. It took 36 years for the underground leak to occur!"

"Unfortunately there was a defective fitting that caused a pipe to burst. The house was vacant so we didn't learn about it until the next day. Alvin bent over backwards to repaire the damage, replace the ruined water heater, and make us whole. He even changed the water heater to a tankless model because the location of the ruined water heater didn't meet code and tankless was our only option."

"Thank you to Geremi and GMC plumbing for all your hard work. They replaced all my pipes, my tub, toilets, faucets and fixtures, my hot water heater and the casing that houses it and they re-dug the sewer line. All this for a very reasonable price and they could not have been any more courteous and professional. Highly recommend this licensed plumber for any project that you have."

"Professional arrived as scheduled and surveyed and discussed problem. Set up equipment and went to work under cleared kitchen sink. Ran equipment thru system and then went to up stairs bathroom shower and cleaned out drain. After interior drains were cleared used rooter tool to clear main drain to street.
Plumber was very professional and provided tips as he worked. He was clean and neat and cleaned up before leaving.
I would use him again and recommend the service to my friends and neighbors.

"I had Glover Plumbing Solutions replace my old yucky tub with a Delta rainforest Walkin Shower, as well as my old tank water heater with a Navien 240A2 tankless water heater and recirculation system. Ryan did a great job with the installation and made sure everything met California code requirements. The workmanship was excellent, everything was tested before he left. Im beyond thrilled he gave me the bathroom of my dreams and im hard to please. I seriously recommend this young man."

"Tony was good mostly. Pros: He was on time every time. This is big for contractors. He was on time for estimates and both times he had to come to place He was the best priced The water heater is installed and working. Cons: His quote was very vague. He told me he would put plywood and install a replacement water heater. And he did. However, the first time he installed was with OSD board...basically looked like junkyard plywood that they put underneath water heater... not good and it was inside my house, maybe if this was in a garage you could get away with it, buy my water heater is in my closet. The first time they came out they installed the wrong water heater, claiming mixup at the warehouse. I can not confirm or validate this, but they did come back the next day with the correct size and also replaced the particle board stuff with real solid plywood that he put a layer of paint on. Once the discovery of the error with the wrong water heater and the bad wood. Communication got very short. He agreed to get replaced then hung up on me. We ended up texting and I offered to pay a bit extra for higher quality material, I just asked that he let me know what that cost would be. He never told me what the new cost would be until the job was completed and I was given the bill. Overall: All in all, he is very well priced, his people were on time and professional, and he did what he said he would do, so he is an honest contractor which is good. My experience was not the best but I would give him a call again however would request a more detailed quote."
