Cured-in-place pipe (CIPP)

Trenchless pipe lining: a new pipe inside the old one.

Pipe lining rehabilitates a damaged sewer line from the inside. A resin-saturated liner is installed through an access point and cured in place, forming a seamless, jointless pipe that seals cracks and root entry points while your driveway, landscaping and hardscape stay where they are.

How it works

How trenchless pipe lining works.

First the line is cleaned thoroughly, usually with hydro jetting, to remove roots, scale and debris so the liner bonds to a clean surface. A camera inspection then measures the line and confirms its condition.

A flexible liner saturated with resin is inserted through a cleanout or a small access point and positioned along the damaged section. It is inflated against the walls of the old pipe and cured until it hardens, creating a new pipe within the old one. Service connections are reinstated, and a final camera pass verifies the result.

Because there is no trench, there is far less restoration: no replacing a driveway, no rebuilding a garden and much less disruption to the household or tenants.

Clean. Hydro jetting prepares the pipe walls.
Line and cure. The resin liner hardens in place.
Verify. A final camera pass confirms the new pipe.

Trenchless pipe lining

Is your line a good candidate for lining?

Lining works best on a pipe that still holds its shape. The camera inspection tells us whether yours does.

Root intrusion at the jointsLining eliminates the joints roots use to get in.
Cracks without collapseCracked pipe that keeps its shape can be lined.
Line under a driveway or slabLining avoids breaking concrete, pavers or flooring.
Mature landscaping aboveTrees and gardens stay put instead of being trenched.
Severe bellies or sagsLining follows the old pipe, so a belly stays a belly.
Collapsed sectionsA collapsed pipe must be opened or replaced first.

Our process

A typical lining project.

Clear steps, explained before anything happens, so you always know what comes next.

Inspect and measure
Camera inspection confirms the condition and length to be lined.
Clean the pipe
Roots, scale and buildup are removed so the liner bonds properly.
Install and cure the liner
The liner is positioned, inflated and cured into a new pipe.
Final inspection
A camera pass confirms a smooth, sealed line before we close up.

Good to know

Pipe lining vs other repair options.

Lining is one of several ways to fix a sewer line. Here is how it compares.

01
Pipe lining
Best for cracked or root-infiltrated pipe that still holds its shape. Minimal digging, minimal restoration.
02
Pipe bursting
Best when the old pipe is too damaged to line or needs a larger diameter. Two small access pits.
03
Spot repair
Best for a single damaged section in an otherwise sound line. One small excavation.
04
Traditional replacement
Best for severe bellies, collapse or when the line must be rerouted. Most excavation.

Cured-in-place liners are designed for a long service life. Results depend on the condition of the host pipe and proper installation, which is why inspection and cleaning come first.

Slightly, by the thickness of the liner. Because the new pipe is smooth and jointless, flow is generally comparable or better.

No. Lining needs a pipe that holds its shape. Collapsed sections require excavation, bursting or replacement.

It depends on length, access and the condition of the line. Lining often saves on restoration costs like concrete and landscaping, which can make it competitive with traditional replacement.

 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!!
