Before a plumber can diagnose low pressure or brown water in Lexington Hills, we need to know who supplies it. The county fire plan annex says about half of homes here rely on wells or springs, and Summit Road parcels have no public water at all, only private wells and tanks. Redwood Estates appears on San Jose Water's service map, so some homes there may be on utility water, and your own address is worth confirming.
That single answer changes everything that follows. A house on a pressure tank and pump has different failure points than a house on a utility main, and a leak on a well system costs you stored water, as well as a bill. Tell the dispatcher what you have, and if you are not sure, we will find out at the pressure gauge.
What to check when the water pressure drops
On a well or spring system, these steps narrow the cause before anyone drives up the grade.
Quick checks before you call
- Read the pressure gauge on the tank. A needle that swings fast between cut-in and cut-out usually points to a waterlogged tank or failing pressure switch.
- Listen at the pump. A pump that runs constantly with nothing open suggests a leak somewhere downstream.
- Check the breaker for the well pump and reset it once. If it trips again, leave it off.
- Look at the storage tank level if you have one, since a low tank can mimic a pump failure.
- Close every tap and watch the gauge for a slow fall, which usually means a hidden leak.
Problem with a well pump, a tank or a backed-up septic line in Lexington Hills? Call (855) 575-2890, any hour.
Call (855) 575-2890Before we arrive in Lexington Hills
Water loss on a well system is urgent because the supply is limited, and our line is open 24/7 for exactly that reason.
- Shut off the main valve at the house, and if you have a well, switch off the pump breaker so it does not run dry or keep feeding a broken pipe.
- Turn off power to the water heater and to any wet room, and keep your hands out of standing water near outlets.
- Move belongings away from the leak, and set a bucket or towels where a ceiling or wall is dripping.
- Call (855) 575-2890 and tell us if you are on a well, spring, mutual water company or utility main, and whether the waste line goes to a septic tank.
Roads here are steep and narrow, so tell us about gates, private roads or a long driveway when you call.
Septic tanks, setbacks and slow drains
The county septic plan says onsite systems are used almost exclusively outside municipal sewer boundaries, and the county Department of Environmental Health regulates them. It does not say every home here is on septic, so confirm yours. A septic home with gurgling fixtures may need its tank checked, more than a drain cable.
The plan also sets a 100-foot setback between a private well or spring and the septic tank and dispersal field. It bans cesspools and notes that older nonconforming systems cluster in the Lexington Basin, where many lots are under half an acre. If you own an older home, a camera and a pumping record tell us far more than a guess does.
Where a lateral or house drain has failed, our sewer line repair service starts with a camera pass so you see the break before you approve work.
Mountain plumbing, three ways we help
Here are three things the dispatch line covers on the mountain.
24/7 emergency dispatch
Emergency dispatch is available around the clock for Lexington Hills, so a live dispatcher takes your call at night and on weekends.
Tank, pump and supply plumbing
We work on the pipes between a well or storage tank and the house, including shutoffs, fittings and leaks.
Septic-aware drain work
We ask how your waste leaves the house before choosing between a cable, a jet or a tank inspection.
Which problem points to which fix?
Use this as a starting point. A plumber on site confirms the real cause.
| What you notice | Likely cause | First step |
|---|---|---|
| Pump cycles constantly | Leak downstream or waterlogged tank | Close all taps and watch the gauge |
| Water bill or tank drops with nothing running | Hidden leak on the supply line | Call for leak detection |
| Gurgling drains and wet ground near the tank | Full tank or failing dispersal field | Stop heavy water use and call |
| White crust on fixtures and heater | Hard well water scaling | Test the water, then discuss a softener |
| Drip at a storage tank outlet | Failed valve or fitting | Close the valve below the tank, then call |
Hard water and well testing
Valley Water says county groundwater averages over 250 mg/L hardness, while its treated surface water averages under 120. If your home draws from a well, expect harder water and ask us about water softener and filtration when scale clogs aerators or coats a heater element.
Valley Water also says domestic well water is not covered by federal or state quality rules, so the owner is responsible for testing and the agency encourages a yearly test at a state-certified lab. Test before you buy treatment equipment, so the system fits the water you actually have.
Fire season, private tanks and your plumbing
The county wildfire annex says nearly the whole area is rated high or extreme risk and that private firefighting tanks may not be full. Responders worry about reliable water supply, which is a good reason to keep your own tank plumbing, valves and fittings in working order.
A corroded valve or leaking outlet on a storage tank can drain the supply you counted on. We can inspect the plumbing on a tank and repair leaks, and a leak-finding visit can trace a slow loss on the line feeding it. Defensible space work is separate, and the county fire department offers a defensible space inspection at no charge for that.
Nearby ZIP codes and neighboring towns
Lexington Hills is an unincorporated community in Santa Clara County that uses ZIP 95033, and we also serve 95030 and 95032 close by. The dispatch line covers sewer line repair and leak detection in those ZIP codes too, so a call from the Los Gatos side of the grade gets the same handling. Coming down the hill, we also cover Monte Sereno and Saratoga.
Lexington Hills plumbing questions, answered
Lexington Hills uses ZIP 95033. Communities within it include Redwood Estates, Chemeketa Park and Aldercroft Heights, and we serve the Summit Road area too. If your mailing address shows a different ZIP, give the dispatcher your location.
Yes. Dispatch is open 24/7, including nights, weekends and holidays. Call (855) 575-2890, give us the location and any gate or road details, and we send a plumber as soon as one is available.
We work on the supply plumbing between a well, tank and house, including leaks and fittings. Well drilling and destruction are licensed separately, and Valley Water's ordinance requires a C-57 contractor for well work.
Possibly, but a clog can cause the same symptom. We check with a camera first, and the county sets rules for tank pumping and inspection, so keep any service records.
County groundwater averages over 250 mg/L hardness, so scale is common on well water. Test your water first, then consider a softener.
Mention private roads, gates and steep driveways. Many Chemeketa Park roads are private, and a clear route helps the plumber we send reach you.
Not necessarily. Chemeketa Park has its own mutual water company, while Redwood Estates appears on San Jose Water's service map. Tell us your supplier when you call.
