I live in Tujunga and woke up to my whole home backing up every drain was clogged and I had no idea what was going on. I searched for plumbers near me and found Drip Too Hard Plumbing, and I’m so glad I did. They came out same day, did a full camera inspection, and showed me exactly where my sewer line was damaged and full of heavy roots. Eric and his team were professional, honest, and explained every step. They ended up digging out the front yard to access the line and installed 10 feet of trenchless liner to rebuild the damaged section. The difference was immediate everything started flowing perfectly again. What really stood out was how clean, organized, and stress-free they made the whole process. Their DTHP Promise gave me a lot of confidence that the job was done correctly and built to last. It’s rare to find a Tujunga plumber that responds this quickly and actually solves the root issue instead of giving temporary fixes. If you’re anywhere in Tujunga or the surrounding area and need reliable help, I highly recommend Drip Too Hard Plumbing. They’re definitely my go-to from now on.

Thank you so much for taking the time to share this. A full home backup is one of the most stressful situations a homeowner can wake up to, and I’m really glad we were able to get out to Tujunga same-day and get everything flowing again. Once we ran the camera and saw how badly the roots had taken over that section of your sewer line, we knew a trenchless liner was the right fix something that would actually solve the problem, not just clear it for a few weeks. Hearing that the difference was immediate means a lot to our whole team. What you mentioned about the process feeling clean, organized, and low-stress… that’s exactly what we aim for with every job. Plumbing issues are already overwhelming, so our job is to make everything else easy and transparent. Thank you for trusting us with such an important repair and for recommending us to your neighbors. We’re always here whenever you need us. — Drip Too Hard Plumbing Glendale Team

I needed hydro jetting at my home in Burbank after my sewer line backed up and called Drip Too Hard Plumbing. Erik came out on a Sunday and showed up right on time, which I really appreciated. He explained the hydro cleaning process clearly and used professional equipment to fully clear the main sewer line. Everything is draining perfectly now. If you're looking for a reliable plumber in Burbank for hydro jetting or sewer cleaning, I definitely recommend Erik and Drip Too Hard Plumbing.

We called Drip Too Hard Plumbing when we needed a sewer line repair at our home in La Cañada. From start to finish, the experience was smooth and professional. They arrived on time, explained everything clearly, and gave us options that made sense without pressure. What really stood out was how clean and thorough the job was—they treated our property with care and got the repair done quickly. It’s rare to find a plumber in La Cañada who not only knows sewer line work inside and out but also backs their work with a solid warranty. That gave us a lot of peace of mind. If you’re looking for reliable, warranty-backed plumbing service in La Cañada, this is the team to call.

San Marino Plumbing Problems We Solve

From older pipes to local water conditions, we've seen it all across San Marino.

Galvanized pipes corroding and restricting flow

Learn more

San Marino's pre-1960s estates often have original galvanized steel pipes that have corroded over decades. The moderately hard water accelerates this corrosion, leading to restricted flow and discolored water throughout these historic properties.

Water heater making popping or rumbling noises

Learn more

The mineral content in San Marino's water supply causes significant sediment buildup in water heaters, especially in older homes near Huntington Library and Lacy Park. This sediment creates popping sounds as the unit heats up and reduces efficiency over time.

Tree root intrusion in sewer lines

Learn more

San Marino's mature oak and pepper trees, particularly in established neighborhoods around Sierra Madre Boulevard, create persistent root intrusion problems in older sewer laterals. These roots seek moisture and can completely block clay and cast iron lines.

Low water pressure throughout the house

Learn more

Many San Marino homes experience declining water pressure due to mineral deposits accumulating in aging copper pipes and corroded galvanized systems. This is especially common in properties built during the post-war expansion of the 1940s-1950s.

San Marino Plumbing FAQs

Common questions from San Marino homeowners about our plumbing services, pricing, and service area.

Absolutely. Many older San Marino homes have galvanized steel or even lead pipes that can rust, corrode, and cause serious plumbing problems over time. Our experienced San Marino plumbers can evaluate your home's pipes and recommend any necessary updates to ensure reliable, safe water flow.
