I’ve hired Drip Too Hard Plumbing multiple times over the past few years for both personal projects and work as a contractor, and they never disappoint. This time, Harry came out to install a Moen Flo Smart Shutoff Valve, and he was on time, professional, and extremely knowledgeable. He took the time to explain how everything works and made sure the installation was perfect. As someone who’s worked with many plumbers in Glendale, I can honestly say Drip Too Hard Plumbing stands out for their reliability, skill, and customer service. They truly care about their clients, and it shows in every job they do. If you’re searching for a plumber near me or someone who can handle smart home plumbing tech like the Flo Smart Shutoff Valve, I highly recommend Harry and the team. Consistently great service from a company I trust for every project.

I have used this company multiple times and in two times for an emergency. They were the first one to respond and they gave me same-day appointments. Their service was excellent and they didn’t even charge for one time because there was not something needed to be fixed. I can’t recommend this company enough they’re my only Plumber that I rely on. Highly recommended.

Just had a water softener install and whole home filter put in by a great plumber in La Crescenta, and I'm really happy how it turned out. Super friendly, showed up on time , and explained everything in a way that was easy to understand. Definitely recommend if you need any plumbing work around here.

Top Plumbing Issues in Monrovia

These issues come up again and again. We're ready for them in Monrovia.

Galvanized pipes corroding and restricting flow

Learn more

Many of Monrovia's 1950s-1970s ranch and craftsman homes still have original galvanized pipes that are now severely corroded. The moderately hard water from Golden State Water Company accelerates this corrosion, leading to restricted water flow and rusty water.

Tree root intrusion in sewer lines

Learn more

Monrovia's mature oak and pepper trees, especially in established neighborhoods like Old Town and Library District, send roots into aging cast iron and clay sewer lines. These roots cause recurring backups and require professional cleaning or line replacement.

Water heater making popping or rumbling noises

Learn more

Hard water minerals from Monrovia's groundwater supply create heavy sediment buildup in water heater tanks. This sediment causes popping and rumbling sounds as water heats, and significantly reduces efficiency and lifespan of the unit.

Slab leak causing foundation concerns

Learn more

Many of Monrovia's ranch-style homes from the 1950s-1970s were built on concrete slabs with embedded copper water lines. Age and ground movement near the foothills cause these lines to develop leaks that can damage foundations and flooring.
