I highly recommend Drip Too Hard Plumbing! They installed a brand-new sewer pipe from my house to the sidewalk with zero issues. Eric took the time to break down every detail and explain the entire process before starting any work, even giving me different options so I could make the best decision. That level of transparency is rare. Harry is incredibly focused and skilled—his work speaks for itself. The whole crew worked clean, fast, and professionally. If you’re looking for a Burbank plumber who actually knows what they’re doing and stands behind their work, these are your guys. The DTHPromise gave me total peace of mind throughout the whole project. Thank you again—I’ll definitely have Drip Too Hard Plumbing handling all my future plumbing projects, especially anything involving sewer line repair.

I was looking for a reliable plumber in Burbank to replace my old water heater, and calling Drip Too Hard Plumbing turned out to be the best move I could’ve made. Erik and his crew came through big time — they installed a new tankless water heater and a whole-house water softener system within the same week. From the very first call, they were transparent, professional, and easy to work with. The team showed up right on time, protected my floors, and walked me through everything step by step. They even fine-tuned my water pressure before wrapping up — something most companies wouldn’t bother with. You can tell Drip Too Hard Plumbing actually cares about their customers and their work. No upselling, no last-minute surprises just clean, high-quality craftsmanship. If you’re in Burbank and need a trustworthy plumber, these are the guys to call. My water feels softer, the pressure’s perfect, and hot water is instant now.

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.
