Plumbing Services
Residential plumbing repair and installation — water heaters, hidden leaks, repipes, gas lines, and fixtures — done by licensed Southern California plumbers, never subcontractors.
Trusted Plumbing Services Across Southern California
A licensed plumber is what stands between a small fix and an expensive surprise. Reliable Pros Services covers the full range of residential plumbing across Los Angeles, Orange, Riverside, and San Bernardino counties — water heaters, hidden leaks, repipes, gas lines, and every fixture in the house.
We never sub the work out. Every job is run by a licensed Reliable Pros plumber driving a fully stocked truck, so most repairs are completed on the first visit. Bigger jobs — a whole-home repipe, a tankless conversion, a gas line for a new range — come with a fixed quote, a permit pulled in your name, and a written warranty.
If your situation is urgent — water under the slab, a heater dumping into the garage, smell of gas — that’s 24/7 emergency, not a scheduled visit. For everything else, pick a window that works for you and we’ll be there with parts on board.

Plumbing Services — Answered
What homeowners across LA, Orange, Riverside, and San Bernardino counties ask us most often. Have another question? Call or write — a real human always answers.
How do I know if a hidden leak is behind my walls or under the slab?
The clearest signs are an unexplained jump in your water bill, the sound of running water when nothing is on, warm spots on the slab, persistent humidity in one room, or mildew on a wall that doesn't sit near a fixture. We confirm with a pressure isolation test and acoustic listening before opening anything — most slab leaks we find are repaired through a 6-inch access, not the whole floor.
Tank or tankless water heater — which is the right call for my house?
Tankless costs more up front but lasts roughly twice as long, never runs out of hot water, and trims your gas or electric bill 20–30%. A standard 40 or 50-gallon tank is cheaper to install and a sensible choice if your existing gas line and venting already support it. We'll size both options for your household and show you the 10-year total cost before you decide — no upsell.
What does a whole-home repipe involve?
We re-run every hot and cold supply line in the house — typically in PEX, sometimes in copper if you prefer — using the smallest possible drywall access points. A standard single-story home is one to three days; a two-story takes a day or two longer. We protect floors and furnishings, restore drywall, and the city inspector signs off before we close walls. Includes permit, full warranty, and pressure test.
Do I need a permit to replace a water heater or run a gas line?
Yes for both in every Southern California jurisdiction we work in. Water heater swaps require a plumbing permit and (for gas units) a venting and seismic-strap inspection. Gas line work always requires a permit, a pressure test, and final inspection. We pull every permit in your name, line-item the cost in the quote at zero markup, and hand you the signed-off paperwork.
What warranty do you offer on plumbing repairs and installations?
Labor is warrantied for one year on repairs and two years on installations. Manufacturer warranties on water heaters, fixtures, and valves pass through to you — typically 6 to 12 years on tanks, lifetime on most premium fixtures. If something we installed fails inside warranty, we come back and fix it at no charge. The warranty is written on the invoice, not buried in fine print.
