DAE Plumbing provides preventive plumbing maintenance in Hollister and the surrounding five-county area for homes, rental properties, and businesses. Maintenance covers water heater and tankless flushing, shutoff valve and supply line upgrades, smart leak monitoring valves, water treatment servicing, and scheduled drain maintenance. Our licensed plumbers find wear before it becomes a leak, with free estimates.
When You Need Plumbing Maintenance
Most plumbing failures give years of warning to anyone who looks. Maintenance makes sense when your water heater has never been flushed or your sink shutoff valves have not been turned in years.
- It also makes sense when rubber washing machine hoses are more than five years old. It makes sense for rental owners who want fewer tenant calls, and for homes that sit empty during travel.
- Businesses with grease-heavy kitchen drains need scheduled line cleaning to avoid backups during service hours. Hard water across the Central Coast speeds up wear on every valve, cartridge, and heater, so a system that is never checked tends to fail all at once.
A maintenance visit costs far less than the water damage from one failed supply line.

What a Maintenance Visit Covers
Each visit is built around the property, not a fixed checklist. For a typical home we flush the tank water heater to clear sediment, or descale a tankless unit's heat exchanger.
- We test the temperature and pressure relief valve and check strapping and venting. We look at angle stops, supply lines, and the main shutoff, and recommend brass quarter-turn valves where old stops have seized.
- We check toilets for silent leaks, test water pressure, and inspect visible piping for corrosion. Where a softener or filter is installed, we check salt, cartridges, and settings.
You get a plain list of what we found, what can wait, and what should not, each with a price.
