"Had our old tank water heater replaced with a tankless model and had a whole house water filter installed at the same time. We had only a vague idea of what we wanted when we started and they were able to help us flesh out our plans without making us feel foolish for not knowing every detail (which wildly some of the other bidders did). They were able to come out fast and did good work, would hire them again in the future."

Guardian Plumbers provides honest, reliable residential and commercial plumbing services in Wildomar and throughout Riverside County. Whether you need a repair, replacement, maintenance, or a new installation, we will be there stat! The level of quality in the products we use and work we provide never fail to supersede our customers expectations.

"Jesse came out to view project and give a quote. He was on time and very helpful. He checked our water main for pressure and found a small leak at one of the joints. He was able to tighten the joint and the leak stopped. He replaced the cartridge in the bathroom sink and was able to reattach the handle. He was efficient and professional. Pricing was reasonable. He tightened the piping to stop the leak rather than pushing for me to replace the joint at this point. If it does continue to leak I will have Guardian replace it for us."

"Excellent service! We scheduled Plumbing Plus to replace the hot and cold cartridge's in a sink faucet and a tub pop-up drain and overflow gasket. Jared N. quickly assessed the problems. The faucet was so corroded with water deposits that it could not be dismantled to simply replace the hot and cold cartridge's. So Jared replaced the entire faucet with a high quality replacement. After the tub pop-up drain was replaced, Jared checked for leaks by looking in a 'trap door' in the ceiling below the tub that was left after the tub was replaced in an earlier remodel. Jared discovered that the entire tub drain was leaking and need to be replaced, which he did. He also corrected a problem with the drain pipe left from the previous remodel. Although the job was much more complex than expected, Jared was professional, efficient, and extremely cheerful throughout . We highly recommend Jared and Plumbing Plus"

From kitchen remodels to full home renovations, we’re your one-stop solution for quality craftsmanship and reliable service.

"We originally wanted to wait until our spa was fully finished to leave a review, but we just had to rave about Gabe and his team. They have been SO easy to work with—and when you’re opening a second spa location in San Diego, easy is everything. Gabe moved fast (he’ll be done by Monday—EEK!), and for business owners, time is money, so having a contractor who’s in and out efficiently is HUGE. During the project, he discovered some mold in the building. Not only did he notify the property owners immediately, but he also took care of the remediation, followed all proper protocols, and handled it all on his own. We’re forever grateful for how quickly and professionally he resolved it. Honestly, our favorite thing about working with Gabe is how he consistently goes above and beyond—especially in ways we didn’t expect, which meant a lot to us as two female business owners. We never once felt taken advantage of, which sadly can be a rare experience in this industry. To give you an idea of how fast he worked: our space includes five treatment rooms, two storage rooms, a kitchen, an office, and a lobby. He redesigned and completed the whole buildout in just over a month. He’s also a great communicator—sending us frequent updates, photos, and videos of the progress, which gave us so much peace of mind since we couldn’t always be on-site. His pricing is incredibly fair and, in our opinion, makes him unmatched in this industry. His work is impeccable, and it doesn’t break the bank. We truly could not recommend Gabe and his team more!"

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

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
