Old Town Newhall, answered 24/7
Newhall is the oldest part of the Santa Clarita Valley, and it shows underground. Around Old Town and Main Street you will find homes and small commercial buildings from well before the tract era, many with clay sewer lines and galvanized supply pipe. New Flow Plumbing inspects these systems with a camera first, then recommends repairs that fit the age of the building.
Local plumber, Newhall
Old Town Newhall grew up around the railroad and Main Street, and the residential streets nearby include homes from the early and mid 1900s alongside later infill. Many still drain through original clay sewer pipe, which tends to crack, shift at the joints and invite roots. Cast iron drains under older homes often scale up inside, slowing every fixture in the house.
Toward Placerita Canyon and the hillier edges of town, lots get larger and more varied, with longer sewer and water runs and more trees overhead. Newhall is part of the City of Santa Clarita and gets its water from SCV Water. That water is hard, so scale shows up in water heaters, aerators and older galvanized lines faster than in many parts of Los Angeles.
Main Street restaurants, shops and offices bring commercial plumbing into the mix, with grease buildup, heavy daily use and older buildings sharing aging lines. For both homes and businesses, sewer lateral responsibility depends on local rules, so check with City of Santa Clarita public works. A camera inspection gives you the facts either way, and the recorded footage is useful when talking with the city, a tenant or a buyer.

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 818-538-4958In older Newhall homes, slow drains usually point to scale inside cast iron pipe, roots in a clay sewer line, or both. Snaking clears a path but leaves buildup behind. A camera inspection shows which problem you have, so the fix matches the cause.
Yes. We clear grease lines, jet drains, repair fixtures and set up maintenance for businesses along Main Street and the surrounding commercial blocks. We can plan work around opening hours to limit disruption, and we explain what we found so you can budget for future maintenance.
Older clay lines are exactly where it pays off. For $199, with eligibility confirmed when you call, we record the line and point out cracks, root entry and separated joints, so you can plan a repair instead of reacting to a backup.
Responsibility for the lateral and its connection to the main can vary outside the City of Los Angeles. Check with City of Santa Clarita public works for your property. We can provide camera footage showing where any defect is located.
