"We had a great experience with Rock Solid Drains. Coltin and Clavey were both exceptionally knowledgeable, professional, and courteous. I don't want to have to call a plumber again, but if I do, I know it will be Rock Solid Drains."

"Had an issue with a broken pull out shower handle. After assessing the issue, the plumber could not replace the old style pull out without risking damage to the pipes. I did my research and knew that this was a possibility due to the age of the handle. Aris first came on a Friday soon after making the request. After the assessment, and the recommendation to replace the internal pipe to a rotating handle, he was able to return early Saturday to finish the job. All in all, I have to say Aris was great in the way he explained the work and the timeliness of getting it done. I would definitely call again if any future plumbing issues come up."

"Very knowledgeable installer. The owner of the company also visited my home to deliver materials and check on the job. Starving Plumbers installed the water heater the day after I called them, so we were without hot water for just a single day. Knowledgeable and very professional. They were about $500 less for a top of the line American Standard Shorty Tank than the price another local plumbing company quoted."

"My water heater was leaking profusely all over my basement floor and needed to be replaced immediately. Usually getting someone to come over in an emergency is not easy, but when I phoned Arreaga Santos Plumbing Santos said he would come over right away, which he did. My heater is in a difficult place and hard to get to, but Santos and his assistant removed it with ease. Not only was this done fast, the minute details that he attended to were performed with great care and very high quality. Also, he's a very nice guy. Based on the entire situation there is no other plumber I would use in the future. Just call him, you will be as happy as I am."

Plumbing FAQs, answered by experts

Successful plumbing depends heavily on your local environment. Novato has expansive clay soils that swell and shrink seasonally, which stresses buried pipes and causes rigid underground connections to fail. The hard, chlorinated municipal water also accelerates scale buildup and degrades certain pipe materials over time. Furthermore, all installations must include flexible gas connectors and water heater strapping to meet strict CA seismic safety standards.

Helpful?

Gather your property records before scheduling a plumbing service. Document your home’s construction year, as pre-1975 houses feature aging galvanized supply lines and clay sewer laterals. Locate your main water shutoff valve and collect your utility account numbers. You should also take clear photos of the issue, track down three to six months of water bills, and note any history of sewer backups in your CA home.

Helpful?

Opening walls for plumbing access exposes older electrical wiring, which triggers mandatory upgrades under state code. In Novato homes with hydronic radiant heating, water heater repairs directly impact your heating system. Under-slab pipe repairs require cutting into the concrete foundation, which impacts structural integrity if done incorrectly. Your contractor will also verify that nearby gas lines remain undisturbed and maintain their required seismic safety valves.

Helpful?

As homes age in Novato, plumbing needs shift based on the construction era. Pre-1970s houses feature failing galvanized steel lines that cause low water pressure and rust. Homes built in the 1970s and 1980s require replacing degraded polybutylene pipes. Older clay sewer laterals are also highly prone to tree root intrusion. A local professional will assess these aging systems and bring them up to current California building codes.

Helpful?

Distinguishing plumbing issues from other home repairs requires careful observation. During the wet winter months in Novato, ceiling stains point to roof or window flashing leaks rather than pipe failures. Gradual water pressure loss at a single fixture indicates corroding galvanized pipes, while district-wide pressure drops indicate a utility outage. Check for yard dampness as well, since expansive clay soils crack both underground pipes and concrete foundations.
