Hollister's tap water is hard, and the city's own water quality report says so. You see it as white spots on dishes and crust on faucets. Homes here vary in age too. The oldest sit near downtown, while new subdivisions are still going up.
ASC Plumbing serves Salinas and the towns around it, and Hollister is part of our service area. When you need a plumber in Hollister, we fix leaks and clear clogged drains in homes and businesses. We also repair and replace water heaters, and we repipe older houses. Call or text (831) 262-9943, and we will look at the job and put the quote in writing.

The city's 2025 water quality report shows where its water came from that year. Half came from the West Hills Water Treatment Plant, which began serving residents in 2017. City wells supplied 29 percent, and the Lessalt Water Treatment Plant supplied 13 percent. The last 8 percent came from Sunnyslope County Water District wells.
The report puts the city's average hardness at 149 parts per million, about 8 grains per gallon. It calls anything over 6 grains hard, and it says hard water can build scale in pipes and on faucets.
The same report recommends periodic draining of the water heater. If the tank rumbles or the hot water runs out early, call us about water heater repair. We also flush and descale tankless water heaters.
Hollister sits in earthquake country. A U.S. Geological Survey field guide says the Calaveras Fault runs through the urban heart of town. Around Dunne Park, slow fault creep has offset curbs and cracked sidewalks. The city's Building Division says its work gives special attention to Hollister's location in a seismic region.
The city's water heater handout says each heater must be strapped so it cannot topple in an earthquake. It calls for two straps, one in the upper third of the tank and one in the lower third. A tank over 52 gallons needs a third strap. Plumbing tape is not allowed as strapping.
The handout also covers the relief valve drain line. It must run to the outside unless the Building Official approves another spot. The end should point down and sit 6 to 24 inches above the ground. Our water heater installation page covers the rest of the job.
Many Hollister homes are fairly new. By Census estimates, half were built in 1991 or later, and a quarter went up in the 1990s. Census permit data shows 155 new single-family homes authorized in 2025. Newer homes still get dripping faucets and stuck shutoff valves, and we repair both.
The oldest homes sit near downtown. The city's history page says those streets filled with houses between the 1880s and World War II. Census estimates show about 7 percent of Hollister homes were built in 1939 or earlier. Houses that old may still have galvanized steel water pipes, which can rust inside and cut water pressure.
A repipe swaps old supply lines for copper or PEX. If the new pipe is copper, the city's report says the water may show a slight blue or green tint. A protective layer usually forms inside the pipe within a couple of days, and the tint should stop.
The city's Utilities Division runs the sewer collection system. Wastewater goes to the city's Water Reclamation Facility, which makes reclaimed water for uses like park irrigation and groundwater recharge. Southeast of the city, Sunnyslope County Water District provides sewer service in Ridgemark.
The pipe from your house to the sewer main is the sewer lateral. The city runs a Fats, Oils, and Grease program for its sewer system. Grease poured down a kitchen sink cools and sticks inside the drain. When a drain or the main sewer line backs up, we clear it.
If sewage is backing up into the house, that is a job for our emergency plumber service. Digging up a sewer lateral is a bigger job. California law has the person doing the digging call 811 at least two working days before the work starts. Utilities mark their own lines, but a private sewer lateral stays unmarked.
