"Scott Fanatizzo was our plumber. First he turned off the water going to all the toilets. Then went outside to check the pressure valve to the house. It was not working and the pressure coming through the house was the same (121) as from the city to the house. After installing a new pressure valve outside, he checked all the toilets inside and found that only one needed the inners replaced. Problem solved. Scott was polite, neat and efficient! He called and left a voice message alerting me that he would be early, plus I received an email from the company telling the name of the plumber that would be doing the work along with his picture. Awesome customer service!! Great company!!"

"Overall, it was excellent. Jerry (the owner) came out and was very straight forward as to what needs to be done. Price (compared to 6 other companies) could not be beat. Work was scheduled reasonably quickly and went smoothly. Problems were discovered after installation and when made aware, Jerry and his crew made sincere efforts to set it right – and were able to solve the issues in couple of visits. All of the crew and management went out of their way to ensure that we were satisfied with the work and overall result. Would definitely consider Liberty Plumbing for future work."

"They went over and beyond the other plumbing companies I called for service. When I called to make an appointment, Brooke informed me that the parts should be covered under warranty; no other company offered this information when I called. I emailed pictures of my existing faucets to Brooke and she took care of the rest. The parts were shipped directly to my house free of charge. Once I received the parts, I contact Brooke to schedule an appointment for install.They were on time and did a professional job."

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

"When I first talked to Al he walked me through some items to see if I could do the repair myself. Once we figured out the level of the repair needed he immediately came over the next morning. By noon that day he had replaced my water heater, brought it up to code and charged a very fair amount. He also removed lines and capped them that were no longer in use that was not related to the water heater replacement. Al is old school and I very much appreciated his honesty as well as trying to work through the problem. Two other companies, they remain anonymous but both are on TV, came out and didn't look at the water repair heater to repair but just gave me an extremely high cost to replace. I have found my "go to" plumber. Thank you Al1"

"I had a brand new water heater installed 5 months ago. It began leaking on Saturday night just as I had a house full of guests staying for the weekend. Disaster! The good old boy plumber that installed it has refused to return phone calls and text messages. Gone. Didnâ t care. . So I was stuck with calling someone who I didnâ t know and get them to do a replacement on Sunday morning. Over a dozen plumbing companies declined. Fortunately I found this company. They came out Sunday morning. Removed the old 75 gallon unit under manufacture warranty and finished the job by late afternoon. ARS did a great job. Morghon Liddel was a real professional. Very neat install. So happy I selected this company. I learned my lesson about hiring a good old retired? Guy, never again. I am very satisfied with ARSrescue"

"I've sent him to a few properties to give me quotes on repairing or replacing both AC and Heating units. I feel like always thinks about the client first. He's great about finding the issue and resolving the problem quickly and as afforable as possible. I've used him for many projects and he'll continue to be my first call with any HVAC needs."

FAQs for water main install, replace or repair projects in San Marcos, CA

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
