Sixteen services, one C36-licensed team, one truck
Jack's Plumbing and Heating has run residential plumbing out of Carlsbad since 1991. Everything below is work we do ourselves — no subcontracted crews, no lead handoffs to a partner company, and no dispatch center in another county deciding who shows up at your door.
That range is deliberate. North County homes rarely fail in isolation: street pressure running above code takes out an angle stop, which soaks a cabinet, which turns out to be the second pinhole leak this year on supply lines old enough to justify a repipe. A team that only does drain clearing stops at the drain. We would rather carry water heaters, slab leak detection, sewer and gas lines, repipes, water treatment and fixture work on the same truck and finish the whole chain in one relationship.
Pick the service you think you need below, or call and describe the symptom — we will tell you which one it actually is.

Water Heating & Hot Water
Tank, tankless and hydronic. Most of what shortens a heater's life in North County is the water itself, so sizing and descaling matter as much as the install.
Tankless Water Heaters
Endless hot water from a wall-mounted unit that only fires when you open a tap. We size, install, and descale Navien, Rinnai, Noritz and Takagi systems across Carlsbad's coastal and inland homes.
- Certified across every major brand
- Annual descaling for hard water
Water Heater Repair & Replacement
Tank heaters that quit, leak, or only run lukewarm — repaired same day where parts allow, replaced properly where they don't. Every install gets earthquake straps, an expansion tank, and a code-compliant T&P line.
- 40–75 gallon tank replacement
- Bradford White & A.O. Smith
Radiant Heating
Hydronic radiant floor and panel heating — boilers, manifolds, zone valves and circulator pumps. It's a rare skill in North County, and one we've kept on the truck for decades.
- Boiler and manifold service
- Zone valve and pump repair
Leaks, Emergencies & Leak Prevention
Finding water where it should not be. Detection first, demolition last — and hardware that shuts the main off before a slow leak turns into a claim.
Emergency Plumbing
Burst supply line, failed water heater, sewage backing up a shower drain — call and we move it to the front of the day. The truck carries the common failure parts, so most emergencies end in one visit.
- Same-day priority dispatch
- Stocked truck, one-visit fixes
Slab Leak Detection & Repair
A warm patch on the floor or a water bill that jumped for no reason usually means a line under the slab has failed. We locate it acoustically and electromagnetically first, then spot-repair or reroute instead of opening the whole floor.
- Non-invasive electronic location
- Spot repair or full reroute
Moen Flo Smart Valve
A Moen Flo watches your main line for pressure drops and micro-leaks, then shuts the water off before a slow drip becomes a flooded floor. We install it on the main, pair it to your phone, and run the health test before we leave.
- Automatic shut-off on leak detection
- Installed, paired and tested
Pipes, Sewer, Water & Gas Lines
The buried and in-wall work. These are the jobs where a camera, a permit and a correctly sized pipe separate a fifteen-year repair from a callback.
Sewer Line Services
Repeated backups, gurgling drains, or a smell in the yard point at the main line rather than the fixture in front of you. We put a camera down the line before quoting, so the repair matches what is actually broken.
- Camera inspection before quoting
- Cast iron and ABS replacement
Water Line Repipes
Once a house starts producing pinhole leaks two and three at a time, patching stops making financial sense. A whole-house repipe replaces the failing supply lines in one pass, with drywall cut cleanly and patched back.
- Copper or PEX, your call
- Most homes done in 2–3 days
Water Service Installation & Repair
The line running from your meter to the house is the one nobody thinks about until it fails underground. We replace and reroute service lines and handle hose bibs, backflow assemblies and main shut-offs at the same time.
- Meter-to-house line replacement
- Backflow and main shut-off work
Gas Line Installation & Repair
New runs for a range, dryer, fire pit or pool heater, plus leak testing and repair on the lines already in the ground. Permitted, pressure-tested and signed off — gas is not the place to improvise.
- Permitted and pressure-tested
- New appliance runs and stub-outs
Fixtures & Everyday Repairs
The calls that make up most of our week. Small jobs still get the same diagnosis, the same flat price up front and the same one-year guarantee.
Faucet Repair & Replacement
Dripping cartridges, corroded angle stops and seized handles — repaired where parts still exist, replaced where they don't. We also set new kitchen, bath, tub-shower and outdoor hose bib fixtures.
- Cartridge and angle stop repair
- Kitchen, bath and hose bibs
Toilet Repair & Replacement
Running, rocking, weak-flushing or seeping at the base — most of it traces back to a flange, a wax ring or a fill valve. We also set one-piece, comfort-height, bidet-seat and in-wall carrier toilets.
- Flange and wax ring repair
- TOTO and in-wall carrier installs
Garbage Disposal Replacement
Humming without turning, weeping from the seam, or tripping the reset button every week means the unit has reached the end. We swap it, re-plumb the drain and dishwasher line, and run it before we leave.
- InSinkErator and Waste King
- Drain and dishwasher line included
General Plumbing Repairs
The unglamorous list: shut-off valves, supply lines, P-traps, laundry boxes, failing shower valves and the drip nobody has been able to find. If it lives on the water side of the house, it is already on the truck.
- Valves, traps and supply lines
- Diagnostics on hard-to-find leaks
Water Quality & Pressure
Two problems that damage everything else in this list. Hard water scales the fixtures and heat exchangers; unregulated street pressure shortens the life of every joint in the house.
Water Treatment & Filtration
North County water runs hard enough to scale a tankless heat exchanger and crust a fixture cartridge within a few years. Whole-house softeners, carbon filtration and under-sink reverse osmosis deal with it at the source.
- Whole-house softener and carbon
- Under-sink RO for drinking water
Pressure Regulator Replacement
We have measured 200 PSI at Carlsbad hose bibs where code tops out at 80. A failed regulator quietly destroys water heaters, angle stops and supply lines, and it is one of the cheapest parts on the house to replace.
- Free pressure test at the hose bib
- Zurn and Wilkins PRVs
How a Jack's service call actually runs
The same four steps whether it is a $200 disposal swap or a whole-house repipe.
- 01
You describe the symptom
You get someone who does the work, not a call center. Tell us what you are seeing — the warm floor, the hissing wall, the water heater that ran cold — and we will tell you what it usually means and what it takes to confirm.
- 02
We diagnose on site
Sewer lines get a camera. Slab leaks get acoustic and electromagnetic location. Pressure complaints get a gauge on the hose bib. We do not quote a repair before we know which one you need.
- 03
Flat price before any work
Estimates are free and the price is fixed before we start. If the diagnosis changes what the job needs, you hear about it and approve it before anything else happens.
- 04
Fixed, tested and guaranteed
We test the repair under real conditions, clean up, and back the parts and labor for a full year. If something we touched fails inside that year, we come back at no charge.
Choosing the right service
Questions about scope, pricing and how we work. Individual service pages cover the technical details for each job.
I don't know which plumbing service I need. Where do I start?
- Describe the symptom and let us do the sorting. A warm spot on a tile floor is usually a slab leak; water at the base of the water heater is usually the tank; every drain in the house running slow at once is the sewer main rather than any one fixture. Call (760) 750-2626, tell us what you are seeing, and we will tell you which service on this page it falls under and what confirming it involves.
Do you repair, or do you only replace?
- We repair whenever the part is still available and the repair will hold. Cartridges, fill valves, angle stops, flanges, zone valves and pressure regulators are all routinely repaired or swapped individually. We recommend replacement when the failure is the equipment itself — a rusted-through tank, a sewer line with multiple breaks, or supply lines producing pinhole leaks in more than one place — and we will explain which situation you are in before you decide.
Which of these jobs can you finish in a single visit?
- Most of them. Garbage disposals, faucets, toilets, pressure regulators, angle stops, general repairs and a straightforward tank water heater swap are typically one visit, because the truck is stocked for exactly that work. Whole-house repipes, sewer line replacements and water service replacements are multi-day jobs, and gas line work and radiant heating depend on permitting and parts availability.
Is Jack's Plumbing residential only?
- Our work is residential — single-family homes, condos, townhomes and rental properties across Carlsbad and North County San Diego. That focus is deliberate. Thirty-five years in the same housing stock is why we can usually name the likely failure from the symptom before we have opened anything.
Which brands do you install?
- Navien, Rinnai, Noritz and Takagi on tankless; Bradford White and A.O. Smith on tank water heaters; Moen Flo for smart shut-off valves; InSinkErator and Waste King on disposals; Zurn and Wilkins on pressure regulators; TOTO, Moen, Delta and Kohler on fixtures. If you already own a unit and want it installed, we will fit it as long as it is a code-compliant match for the application.
How do I get a price for something on this page?
- Estimates are free and we quote flat rates, not hourly. For most jobs we can give you a realistic range over the phone from the symptom alone, then confirm the exact figure on site once we have diagnosed it. You approve the number before any work begins, and it does not move unless the scope does.
