Expert Tankless System in Glendora, CA

A tankless system heats water on demand instead of storing a tank full all day. That means no standby energy loss and no running out of hot water mid-shower. For Glendora homeowners, one local factor matters more than most: hard water. The San Gabriel Valley water supply carries high levels of calcium and magnesium. Those minerals build up inside a tankless heat exchanger, drop efficiency, and trigger fault codes if the unit is not sized and maintained correctly. Jeremy, a 20-year plumbing veteran and army veteran, assesses your gas line capacity, venting path, and household hot water demand before any work begins. That honest upfront look means the system is matched to your home, not just installed and left. Plumbing Buddies serves Glendora, San Dimas, Covina, West Covina, La Verne, Pasadena, Upland, Claremont, Rancho Cucamonga, Monrovia, and Arcadia. Call us to talk through whether a tankless system fits your home.

Tankless System FAQ

Common questions about tankless system in Glendora, CA.

A tankless system works well in most Glendora homes when the gas line is sized for the load and venting is correct. Jeremy reviews both before recommending a unit so you know what you are getting into.

Hard water is the main cause. High calcium and magnesium levels in the local water supply coat the heat exchanger with scale, which drops efficiency and causes error codes. Regular descaling protects the unit and keeps it running correctly.

Yes, we handle tank-to-tankless conversions for homeowners in Covina and across the service area. We check your existing gas line and venting before the work starts so there are no surprises.

Installation covers confirming gas supply capacity, setting the correct venting path, mounting the unit, and running a full system test. Every step is checked before the job is closed out.

Yes, annual descaling is important for West Covina homes because of the area's hard water. Skipping it lets mineral scale build up inside the heat exchanger and shorten the unit's life.

Ezra and Jose from Plumbing buddies were very professional and respectful of our property and always showed up on time and cleaned up after themselves.Ezra explained what was going to happen once our water got shut off. They began the re-piping under the house with ABS drain lines. finished one day and the 68 year-old cast-iron pipes are now gone. The new black ABS drain pipe should last for a long time. Highly recommend this company.

Recently got a tankless heater installed and Jeremy explained everything in detail. The quote was also fairly priced. The final work looks great. I would highly recommend Plumbing Buddies to anyone looking to repair or replace their water heater. I’ll be using them for yearly maintenance.

I’m writing on behalf of my mom, Nora. Jeremy was excellent to work with from start to finish. He came to my mom’s house to inspect and remove her old water heater and install a new one. Jeremy was professional, punctual, friendly, and communicated clearly throughout the entire process. He took the time to explain everything and made sure all of her questions were answered. She also appreciated how clean and organized he kept his work area from start to finish. The installation was completed efficiently and with great attention to detail. Most importantly, my mom now has the peace of mind that comes with a brand-new water heater and knowing the job was done right. She is very pleased with Jeremy’s service and would highly recommend him to anyone looking for a reliable, knowledgeable, and trustworthy plumber. Do not hesitate to call Jeremy for all your plumbing needs!

They did a great job of replacing the cover for my water heater. It came out great plus after the rain it was making a noise and they came quick to check it out and clean it! They are the best 😊🙏🏼!

One of the good guys out there. He is the only plumber we trust and we have used him on many projects. Jeremy will give you honest feedback and does great work. We’ve now used Plumbing Buddies several times and couldn’t be happier!
