Sylmar plumbing, around the clock
Sylmar is the northernmost neighborhood of Los Angeles, running up to the San Gabriel Mountain foothills, with horse properties, older ranch homes, newer tract developments and mobile home communities. Many lots are large, and water and sewer lines run longer distances. New Flow Plumbing diagnoses with cameras and locating tools before recommending a repair.
Common in Sylmar
Lot size, terrain and a wide mix of housing make Sylmar plumbing calls more varied than most. These are the issues we see regularly.
Local plumber, Sylmar
Sylmar takes its name from the olive groves that once covered the area, and pockets of that rural character remain. Horse properties and larger lots along the foothills often have barns, guest houses and outdoor water lines spread across the land. Long water services and sewer runs mean leaks can go unnoticed for a long time, and finding them takes proper locating equipment.
Elsewhere, Sylmar has postwar ranch homes and newer tracts built in later decades, along with mobile home communities. Each type has different plumbing. Older houses may still have clay laterals and galvanized pipe, while newer homes are more likely to need fixture, water heater or pressure work. Sloped streets near the foothills can affect how sewer lines are laid out and how they age.
Sylmar sits in an area with a long seismic history, including the 1971 San Fernando earthquake, so flexible water heater connections and proper strapping matter here. Water comes from LADWP. Sylmar is part of the City of Los Angeles, so property owners are generally responsible for the sewer lateral from the house to the public main. On a big lot, that can be a long stretch of pipe.

Call 818-538-4958We use pressure testing and acoustic listening equipment to trace the line and pinpoint where water is escaping. That narrows the dig to a small area instead of trenching across the whole lot, which matters when lines run under pasture, arenas or long driveways.
California requires water heaters to be braced against earthquakes, and Sylmar's seismic history makes it especially worthwhile. If your straps are missing or loose, we can install or update them during a repair or replacement.

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.Posted on 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.Posted on 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.Posted on 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.Posted on 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.Posted on 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.Posted on 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.Posted on 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.Posted on 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.Posted on 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!!
Call us any hour and we will track down the problem, even on a big lot.
