C-36 licensed, CSLB #568271. Serving El Cajon and East County since 1989. Helix Water District water runs hard — about 12 grains per gallon — and East County's older homes bring their own plumbing quirks. We handle both.
Helix Water District (which also serves La Mesa, Lemon Grove, Spring Valley, and parts of Lakeside) reports hardness right in its CCR: an average of about 205 mg/L, or 12 grains per gallon, ranging up to 18.5 gpg depending on source. That's solidly “hard” — enough to scale a water heater early. Pair that with El Cajon's older housing stock and slab foundations, and slab leaks and aging galvanized lines are common calls.
Hardness figures: Helix Water District / California State Water Resources Control Board Consumer Confidence Report 2023 (PWS ID CA3710010).
El Cajon's older slab homes and aging copper bring slab leaks and pinhole leaks. We locate the leak and repair it — no guesswork, no tear-out we don't need.
Older homes with galvanized or polybutylene lines corrode faster in hard water. We repipe in PEX-A — licensed, permitted, inspected. No subcontractors.
Camera inspection to find root intrusion, mineral buildup, or offset joints before they back up. We diagnose and repair — no snake-only service calls.
Hard water is brutal on heaters. We service, descale, and install tank and tankless systems sized to your home and code.
Natural gas and propane lines for appliances, BBQs, and generators. CSLB C-36 licensed for all gas work — permitted and pressure-tested.
We rough in and connect whole-house softeners and RO systems. We don't sell the units — we make sure the plumbing is right.
In hard water, your water heater anode burns out years early. JPS-AP members get an annual water heater service, whole-house inspection, sewer camera check, front-of-line scheduling, and 25 JPSAI questions/day. One plan, no contracts.
