Water heater repair

Signs your water heater needs attention.

Water heaters usually give warnings before they fail. Catching them early can save the tank and the floor around it.

Water around the baseA leaking tank usually means replacement. Fittings and valves may be repairable.
Not enough hot waterSediment, a failed element or a thermostat issue can all shorten hot water supply.
Rumbling or poppingSediment buildup on the bottom of the tank, common with hard Valley water.
Rusty or discolored waterCorrosion inside the tank or a failing anode rod.
Pilot will not stay litThermocouple, gas valve or venting issues on gas units.
Tankless error codesScale, ignition or flow problems that need diagnosis.

How it works

Repair or replace: how we decide with you.

The first question is whether the tank itself is leaking. A leak from the tank body cannot be repaired, so replacement is the answer. Most other failures, from a thermostat or heating element to a gas valve, igniter or thermocouple, are often repairable at a fraction of the cost of a new unit.

Age matters too. A unit near the end of its expected life with a costly repair may not be worth fixing, while a newer unit almost always is. We lay out both numbers so you can decide.

When replacement makes sense, we explain the options, including tank and tankless, and handle the installation with current code requirements and removal of the old equipment.

Tank leak. Replacement is the safe answer.
Component failure. Often repairable at lower cost.
Older unit, big repair. We compare both options honestly.

Good to know

Tank or tankless: what to consider.

If replacement is on the table, these are the questions we walk through with you.

01
Household demand
How many showers, appliances and people use hot water at the same time.
02
Space and venting
Tankless units free up space but may need venting and gas line changes.
03
Upfront vs long-term cost
Tank heaters cost less upfront; tankless units can lower energy use over time.
04
Water quality
Hard water in parts of LA shortens the life of both types without maintenance.

 Trustindex verifies that the original source of the review is Google. New Flow came out to my mothers house in Reseda and was able to clear the main line blockage. They were there within an hour and had very reasonable pricing. While there they identified another problem with the pipping(it is a 100 year old house lol) and came up with an option to replace some of the pipping.
Definitely will be using them again for any problems down in the valley.

 Trustindex verifies that the original source of the review is Google. Whenever something goes wrong at our North Hollywood condo property, Art answers the phone day or night, which is why New Flow Plumbing has handled our plumbing since the place was built. Just last week a huge problem hit at 10:00 pm with all the tenants stressing out, but they had someone walking through the door in twenty minutes to get it taken care of. They show up ready to work seven days a week for the small stuff and the emergencies alike, so I always know we are covered.

 Trustindex verifies that the original source of the review is Google. Had a sewage back up at a unit and Art was able to take care of my problem. Due to it being an older house it had quite significant problems (old piping, no clear out,etc). He took care of the clog, add clear out, and also discovered the toilets that were installed were incorrect ones since forever and replaced both toilets as well. He also gave me advice on what he would do with the current drainage problem and what he would do temporarily, and or the future for my piping. Was very reasonably priced. 100% satisfied with the service he provided.

 Trustindex verifies that the original source of the review is Google. Shower was way too cold. Looked at the tank and could tell it was completely done, so we reached out to New flow to fix the plumbing in Granada Hills. The tech got the new hot water heater put in and even cleaned up some sloppy copper fittings left behind from our previous remodel so everything lined up straight. He was wrapped up and out the door by 3p, and the hot water was running before he left.

 Trustindex verifies that the original source of the review is Google. Water was backing up into both my toilet and bathtub from a main line clog. A few plumbers gave weird replies, including one guy who threw out a random quote without even checking the pipes. I usually handle small things myself, but I needed real help here. Art came in and mapped out the whole line, running a camera to show me the blockages on the screen. He pushed past 60 feet clearing tree roots and debris, explaining the fix as he went. The final bill matched his quote. Thanks to them I can finally take a shower.

 Trustindex verifies that the original source of the review is Google. Great work from the best plumbers in the valley. I had a pretty big job done. They replaced the main water pipe out to the street. It was completed on time and they kept me informed during the down time (waiting for the city to approve the permit.) I would use them again. They are pleasant to work with.

 Trustindex verifies that the original source of the review is Google. If you need a reliable plumber in Valley Village, save their number right now. Our new tenants moved into our rental last weekend and immediately hit us with a no hot water text. Found New Flow on Google, liked what I saw on their page, and gave them a call.
Arman sent someone out just a few hours later. We looked at the old twenty year unit and agreed a full replacement made the most sense. They knocked it out the exact same day, saved my weekend, and kept the tenants happy. Already passed his name to a buddy of mine who hired him shortly after.

 Trustindex verifies that the original source of the review is Google. My parent's toilet was leaking and after messaging different places, I told my parents this place could fix our problem. Arman was the one who helped us out and after talking to him about a possible broken wax ring, he found the actual problem, roots in our pipes. He hydrojetted the roots and installed something to help keep the roots from growing for the next few years. So if you're have problems related to pipes, my family and I highly recommend coming here.

 Trustindex verifies that the original source of the review is Google. We have been calling New Flow for plumbing services ever since they warned us six years ago that our ancient drain pipes were on their last legs. When the system finally failed, we shopped around for bids on a full repipe. Every single plumber gave us quotes without stepping foot under the house, except them. The team crawled under there, filmed the pipes, and showed us that our water lines were still completely fine. Arman gave us a fair quote for just the drains, and his crew finished the work in one day. Hard to find contractors this upfront and genuine.

 Trustindex verifies that the original source of the review is Google. I cannot compliment New Flow Plumbing enough. They were recommended by our selling real estate agent for a sewage line inspection. They came out quickly, and Arman was very professional and polite right away. He was able to service the sewage line, provide thorough, expert knowledge, and give us recommendations. The pricing is excellent and fair, and I would definitely recommend using their services again. The HD video was provided for our own viewing, and it was emailed to us within hours of the visit. Overall a very enjoyable experience.

5 stars does not do it justice.

Thanks again!!

A leaking tank needs replacement. Most other failures are repairable. For older units facing an expensive repair, replacement may be the better value, and we will show you both options.

Tank water heaters commonly last around 8 to 12 years, and tankless units longer with maintenance. Hard water and lack of flushing shorten both.

Yes. We diagnose error codes, scale buildup, ignition and flow issues on tankless units.

Usually sediment on the bottom of the tank. Flushing can help; heavy buildup on an older unit can mean it is nearing replacement.
