Granada Hills, answered 24/7
Granada Hills sits at the north end of the San Fernando Valley, where flat ranch home streets rise toward the foothills near O'Melveny Park. Most homes date from the 1950s and 1960s, including the well-known Eichler homes of Balboa Highlands. New Flow Plumbing helps Granada Hills owners keep aging plumbing working, starting every job with a clear diagnosis.
Common in Granada Hills
Midcentury construction and decades of tree growth explain most of the plumbing calls we get from Granada Hills. These issues come up most often.
Local plumber, Granada Hills
Much of Granada Hills was built during the postwar boom, and its streets are lined with single story ranch homes on concrete slabs. Water lines often run under those slabs, and after many decades, pinhole leaks in copper pipe are a common call. Sewer laterals from the same era are frequently clay or cast iron, both of which crack and corrode with age.
The Eichler homes in Balboa Highlands deserve special mention. These midcentury modern houses were built with radiant heating pipes in the concrete slab, and their open designs leave little room to reroute plumbing. Working on them takes care and an understanding of how they were built. North of the flats, foothill homes near O'Melveny Park sit on sloped lots with longer laterals.
Granada Hills is part of the City of Los Angeles and is served by LADWP, with the Los Angeles Reservoir just to the east. The city maintains the public sewer main, while owners are generally responsible for their lateral. Mature trees planted when the neighborhoods were new now have large root systems close to those lines, and many laterals have never been inspected since the homes were built.

Call 818-538-4958Yes. Eichlers in Balboa Highlands were built with radiant heating in the concrete slab, so locating leaks accurately is especially important. We use leak detection tools to find the source before recommending a spot repair or a reroute, keeping disruption to the home's finishes as low as possible.
Many homes were built in the 1950s and 1960s with copper water lines under concrete slabs. Over decades, water chemistry, pipe contact with concrete and ground movement can wear through the pipe walls and cause small leaks that are hard to spot.
It can be. Root intrusion and cracks often develop slowly, long before a backup. For an older home, seeing the lateral's condition on camera helps you plan ahead. We confirm whether your property qualifies for the $199 price when scheduling.
It depends on the pipe's overall condition. One leak in otherwise sound pipe may justify a spot repair. If the line has had several leaks or shows widespread wear, rerouting through walls or the attic usually prevents repeat problems.

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 New Flow at any hour and we will help you find a lasting fix.
