Water pressure regulators in Lake Sherwood

5.0 on Google (20 reviews) CSLB Lic. #339618 Family shop since 1977

Water pressure regulators in Lake Sherwood, ten minutes, over the hill from the shop in Westlake Village. Conejo Valley water comes from tanks on the hills, so on many streets it arrives above the 80 psi code allows in a house.

Dan picks up when he can and calls back the same day. You get the price before we start. Monday to Friday, 9am – 5pm.

Around here

In Lake Sherwood

A Lake Sherwood property often runs the house, the irrigation and the pool equipment off one main, and the side with no pressure regulator is the one that starts failing. In March 2026 we found several irrigation leaks here, all from street pressure with nothing holding it back. We put in two shutoffs, a regulator and a relief valve, then fixed the leaks.

Neighborhoods: Sherwood Country Club, the lake, the Hidden Valley edge, the older lakeside streets.

The job

How it goes

A regulator is a valve on the main line, usually near the front hose bib. It takes street pressure, 100 psi and more here, and holds the house at 50 to 70. When one fails after ten to fifteen years, pressure creeps up and fill valves, angle stops, cartridges and washer hoses start breaking.

A gauge on a hose bib tests it in a minute. Over 80, or a swing when a fixture shuts, means it's done. Replacement takes a few hours, with unions so the next swap is easier. If the water heater has no expansion tank, we add one.

We check the pressure at every house we work in. Here, it's the most useful thing to know.

Your house has never had one

Several irrigation leaks on one property, all from street pressure with no regulator on that side. Over two visits we installed an irrigation shutoff, a house shutoff, a pressure regulator and a relief valve, then repaired the leaks and replaced three sprinkler valves.

Common questions

Pressure regulators in Lake Sherwood: things people ask

Do you go through the gate at Sherwood?

Yes. We call ahead with the truck and name so the gate expects us, or your estate manager can set it up with us directly.

How fast can you get to Lake Sherwood?

Often the same day. It's ten minutes over the hill. For planned work on a big house, we walk it first.

What should my water pressure be?

Between 50 and 70 psi. Code allows up to 80. Above that, most fixture warranties are void.

Where is my regulator?

Near the front hose bib or main shutoff. It's a bell-shaped brass valve with a screw on top.

Can I test the pressure myself?

Yes, with a hardware-store gauge on a hose bib. Over 80, or a big swing when a tap runs, means it's due.

More in Lake Sherwood

Plumber in Lake Sherwood Everything we do in Lake Sherwood. Leak detection in Lake Sherwood Leak detection at Lake Sherwood usually means finding the quiet one: a line out to a guest house or the pool equipment, or an irrigation lateral, that's run for months before the bill gives it away. At the meter we separate the house from each outbuilding and from the irrigation, then narrow it down. We set up gate clearance before we come. Water heaters in Lake Sherwood Houses at Lake Sherwood often run two or three water heaters on a recirculation loop, and when one fails, nobody's sure which. Tankless in Lake Sherwood Around Lake Sherwood, a tankless install is usually a conversion on a big house that already runs more than one heater, and the recirculation loop has to keep working afterward. Sizing the gas from the meter is most of the job. We test the line under pressure, fit isolation valves for the yearly descale and permit it through Ventura County. Drain cleaning in Lake Sherwood Drain cleaning at Lake Sherwood is mostly the older houses by the lake, where the plumbing has been added onto by a long line of people. Repiping in Lake Sherwood Repiping a large Lake Sherwood house comes down to the order of work. Repairs in Lake Sherwood Lake Sherwood is gated, so we clear the truck with the gate before any plumbing repair visit. Sewer camera & repair in Lake Sherwood At Lake Sherwood the sewer runs to Triunfo Water and Sanitation District, and on lots this size a camera inspection covers a long line from the house to the main. We run it from the cleanout and mark the fault and its depth on the surface. On the older lakeside houses, it often turns up work nobody has a record of. Gas lines in Lake Sherwood On a Lake Sherwood property, gas lines run to the guest house, the pool equipment and an outdoor kitchen, so the sizing comes off the whole load at the meter. Each line is black iron with a shutoff at the appliance, pressure tested and permitted through Ventura County. We arrange gate clearance before we come. If you smell gas, leave and call SoCalGas. Slab leaks in Lake Sherwood Before a slab leak can be repaired at Lake Sherwood, we have to rule out the guest house, the pool equipment and the irrigation, since any of them can turn the meter too. Once they're isolated and hot is split from cold, the leak-locating specialist we bring in marks the spot under the concrete. Then it's a spot repair or a reroute overhead.
