Trusted across the San Marino area for honest pricing, clean work, and real warranties.
As a property manager living out of state, finding a truly dependable Glendale plumber has been a huge relief. Drip Too Hard Plumbing handles maintenance across several tenant properties for us, and they’ve delivered every time especially in emergencies. We’ve had a few serious situations: an old water heater burst and left tenants without hot water, a backed‑up sewer line, and unexpected leaks. Drip Too Hard responded fast, installed a new tankless water heater on short notice, cleared sewer line clogs, and repaired leaks promptly. That mix of emergency skill plus everyday maintenance is exactly what remote managers need. Communication is another standout. They keep me in the loop with clear explanations, photos when needed, and honest recommendations. Tenants feel taken care of, and I’m not left guessing about costs or next steps. It’s rare to find a crew that’s both technically sharp and good at working with owners who aren’t on site. If you manage properties from another state or just want a go‑to local plumbing partner in Glendale, this is the team to trust. Reliable, professional, and genuinely helpful highly recommended.

Thank you for the kind review and for trusting us to take care of your properties. We understand how important it is for an out-of-state property manager to have a reliable Glendale plumber they can count on, especially when emergencies come up. We’re glad we could help with everything from emergency tankless water heater installation to sewer line unclogs and leak repairs, and even more glad that the communication and transparency made managing your tenants easier. Taking care of your tenants as if they were our own is always our priority. We truly appreciate the continued trust and look forward to supporting your properties for years to come. — Drip Too Hard Plumbing
I needed an emergency plumber in Burbank near the Hillside area, and I’m honestly grateful I found Drip Too Hard Plumbing. They showed up on time and immediately made me feel like my home was in good hands. Harry walked me through every step of the process, and Jon made sure the work was done clean and professionally. They performed a full hydro jetting on my line and also handled a tankless water heater replacement the same day. What really stood out was the transparency, the communication, and the DTHPromise they give you real peace of mind from a company that stands behind their work.If you’re looking for a Burbank plumber you can trust, especially for emergencies, I highly recommend Drip Too Hard Plumbing. These guys are the real deal.

Thank you for sharing this, and we’re really glad we could help during your emergency in the Hillside area of Burbank. When you call us for urgent drain cleaning or a tankless water heater issue, our goal is to make sure you feel exactly what you described — that your home is in good hands from the moment we arrive. Harry and Jon take a lot of pride in walking customers through every step, keeping the work clean, and making sure the job is done right. The DTHPromise is all about transparency, communication, and standing behind our work, especially on same-day hydro jetting and water heater replacements. If you ever need a Burbank plumber again — whether it’s an emergency, drain issue, or another install — we’ll always be here for you. Thank you for trusting Drip Too Hard Plumbing.
We had this plumber in La Crescenta come out for a water softener install and a whole home filter. Super easy to work with, showed up when they said they would, and the water in our house is already so much better. Definitely recommend if you need a water softener or just a good plumber.

Thank you for trusting Drip Too Hard Plumbing with your water softener and whole home filter install! 💧 We’re glad to hear everything went smoothly and that you’re already noticing the difference in your water quality. Our team takes pride in being on-time, easy to work with, and delivering results you can feel right away. We appreciate the recommendation — that’s the DTHP Promise in action. 🙏 - Erik, Owner, Drip Too Hard Plumbing
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.
