Pool re-piping in Los Angeles replaces the suction and return lines when patching stops making sense, usually on older pools where leaks keep coming back. In-ground leak repair runs $350 to $2,700 per HomeAdvisor’s 2026 data, and once a system needs repeat repairs, a full re-pipe often costs less than the next round of patches.

Repair or Re-Pipe?
Most leaks are a repair, not a re-pipe. One cracked fitting or a single broken section on otherwise healthy pipe gets fixed and the pool goes back to normal.
Re-piping makes sense when the system itself is failing:
- Leaks keep coming back in new places after each repair
- The lines are original galvanized steel or brittle early plastic
- Several lines fail a pressure test at the same time
- A remodel already has the deck torn up
- New equipment needs larger lines than the pool was built with
| Situation | Usual approach | Typical cost |
|---|---|---|
| One damaged line, the rest in good shape | Repair that section | $350 to $2,700 |
| Repeated leaks on old galvanized or early PVC | Re-pipe the affected runs | Quoted per project |
| Remodel with the deck already open | Re-pipe everything at once | Quoted with the remodel |

If you have one known leak, start with a diagnosis and pool plumbing repair. We only recommend new lines when repairs have stopped paying off.
Why Older Valley Pools Need It
Many Valley pools went in during the 1950s and 1960s, and their original lines are now well past their expected life. Galvanized steel corrodes from the inside and narrows over time. Early plastic lines turn brittle and crack with ground movement.
Original postwar plumbing is why re-piping Van Nuys pools comes up so often. Older tracts further west bring us Woodland Hills re-pipes as well.

How the Work Is Done
- Test every line. Each suction and return line is pressure-tested to confirm which ones have failed and which can stay.
- Plan the routes. New lines are routed to reach the equipment pad with as few deck cuts as possible. Sometimes old lines are abandoned in place and new ones run a better path.
- Open and replace. Trenches are dug, the new pipe is laid and connected at the pool fittings and the pad.
- Pressure-test before backfill. Every new line holds pressure before it is buried.
- Restore. Trenches are backfilled and the deck is patched, or rebuilt if deck work is part of the project.
What the New Lines Are Made Of
Older pools used galvanized steel because it was the standard at the time. Today’s pool plumbing is rigid PVC rated for pressure, with flexible PVC only where a line has to bend around an obstacle. PVC does not rust, so it does not narrow from the inside the way old steel lines do.
We match the pipe size to the flow the equipment needs, which is often larger than what the pool was built with decades ago.
Better Flow, Lower Power Bills
Undersized or corroded lines make the pump work harder to move the same water. New pipe sized for today’s equipment lowers that resistance, which lets a variable-speed pump run slower and use less power. New lines pair well with a new equipment pad for that reason.
What to Expect During the Job
Many pools can stay full during the work, with the lines plugged at the pool while the new pipe goes in. Skimmer work may need the water lowered for a day. The pump is off while lines are disconnected, so plan on a few days without circulation. We keep the trenches as narrow as the work allows and restore the deck or planting afterward.
What Re-Piping Costs
Replacing the lines is quoted per project, because the price depends on how many lines are replaced, how far they run and what sits on top of them. Concrete and pavers cost more to open and restore than soil or planters.
For comparison, a single in-ground leak repair runs $350 to $2,700, according to HomeAdvisor’s 2026 data. When a pool needs that repair every year or two, replacing the failing lines often costs less over time.

The Best Time for New Lines
The cheapest time is during a pool renovation. When the deck is already coming out, the trenching and restoration costs are shared with the rest of the project instead of paid twice. If the old slab is due for replacement anyway, the new lines go in before the new pool deck is poured.
Ask any contractor to show you the pressure-test results for each line. That tells you which lines are failing and which can stay.
Before signing with anyone, run through nine questions for any pool contractor. A good contractor will explain which lines are failing and why.
Most re-pipes take a few days to a couple of weeks, depending on how many lines are replaced and how much deck has to be opened.

Frequently Asked Questions
How much does it cost to replace pool pipes?
Replacing a single damaged pool pipe typically falls within HomeAdvisor’s 2026 range of $350 to $2,700 for in-ground leak repair, with the depth of the line and what sits above it setting the price. A full re-pipe replaces several lines at once and costs more, because it involves trenching, removing deck sections and reconnecting the equipment pad. We trace every line first and quote the whole job in writing before any digging starts.
What type of pipe is used for inground pools?
Most inground pools use Schedule 40 PVC pipe, which is rigid, resists pool chemicals and handles the pressure a pump creates. Lines are usually 1.5 or 2 inches wide, and larger pools or long runs to the equipment pad often use 2-inch pipe so the pump does not have to work as hard. Some older pools still have copper or galvanized lines, which corrode over time and are a common reason for a full re-pipe.
How do you repair a broken pool pipe?
You repair a broken pool pipe by locating the break, exposing that section, cutting out the damaged piece and gluing in new PVC with couplings. The line is then pressure tested before it is covered again. When the break sits under a deck, a small section of concrete is cut out and patched afterward. If the same line has broken more than once, replacing the whole run is usually the longer-lasting repair.
How do I fix a leaky pipe without replacing it?
You can sometimes fix a leaky pool pipe without replacing it by lining it from the inside with an epoxy coating or an internal sealant. That approach suits pipe that is still in good shape overall but has a pinhole leak or a small crack. It does not hold on lines that are crushed, pulled apart at a joint or badly corroded. When a pool keeps developing new small leaks, a partial or full re-pipe is usually the better investment.
