Unusual Water Pressure Drops: Sudden changes in water pressure may suggest backflow issues or valve failure.

Rafael is an excellent plumber. Honest, knowledgeable, helpful and great communicator. Addressed an outdoor backyard spigot issue quickly and carefully. The replacement spigot system is better and more modern than the original that came with the house.

I had Robby J. come out and take a look at my spare bathroom valves and we had some issues finding a replacement valve at first but we did find one. Since I have an older home it’s been difficult repairing/replacing certain things which has been incredibly frustrating. But Robby was a big help on walking me through everything and even provided me with some financing options to lessen the blow which makes me incredibly happy that I have options. Thank you again for really helping me figure out my next steps and what options would guarantee a long-term solution. I appreciate your time and what you do for the community.

Follow-Up 18 May 2026:
First off, every employee has been kind and courteous. This actual physical installation of the system is great, the plumbing is clean and tidy and looks great. The problem is the system. It really hasn’t worked, or at least hasn’t worked like I expected. I get a maximum of 100 gallons of water before iron starts to appear in the water again. When I got the work done I was given three options, so I the middle priced option that was presented as a “good” option, but not then “best” or “Peace of Mind” as Olympic put it. Anyway, I had a tech come back out and they checked the controller setting and nothing seemed out of order. I am still having them problem, and yesterday 17 May, the system only gave me 60 gallons of water before iron/color came back into my water. I have another appointment today 18 May, and will continue to post updates. No one ever told me what kind of Iron is in my water, but I think the “Good” system option would still give me enough water to have hundreds of gallons. Right I have to regen every day, maybe twice because if our water needs. I hope they can come up with a solution.

Once he got to my home he apologized for the time it took to get back to me. He went straight to work. He had to snake out the sink three times. Finally got it cleared. He gave me suggestions to make clearing clogs better next time He was very polite and professional.
