Your home's main water line is its lifeline. Izzy Plumbing Inc. delivers expert main water line repairs, trenchless installations, and pressure regulator services — protecting your supply from the street to your fixtures.
What We Do
From buried main line repairs to trenchless replacements and pressure regulators, Izzy Plumbing has your home's water supply covered end-to-end.
Fast diagnosis and repair of breaks, corrosion, root intrusion, and joint failures in your home's primary supply line — minimizing water loss and property damage.
Full main line replacement without tearing up your yard or driveway. Our trenchless pipe-bursting and directional drilling methods protect your landscaping investment.
High water pressure silently damages fixtures, appliances, and pipes. We test, adjust, and replace pressure-reducing valves to keep your system at the safe 40–80 PSI range.
Underground water line leaks can go undetected for months, driving up bills. We use electronic listening devices and pressure testing to pinpoint leaks with pinpoint accuracy.
Adding an ADU, extending your home, or replacing an undersized service line? We size and install new water service from the city tap to your home to code.
A burst main line can flood your yard or cut all water to your home. Izzy Plumbing dispatches same-day for emergency shut-off, temporary bypass, and permanent repair.

Don't Ignore the Signs
Catching a water line problem early saves thousands in repair costs and prevents structural damage to your property. Know these six red flags.
A significant or unexplained pressure drop throughout the entire house — not just one fixture — usually indicates a main line break or serious blockage.
Pools of water, unusually soft ground, or lush green patches in a drought-dry yard signal an underground main line leak losing water into the soil.
An unexplained jump in your water bill — with no change in usage habits — often means a hidden underground leak is running 24/7.
Brown, orange, or sediment-heavy water at every tap points to corroding main line pipes introducing rust and debris into your supply.
"Water hammer" — loud banging when you open or close a tap — often signals unregulated high pressure that will eventually rupture supply lines or damage appliances.
Visible depressions or washed-away soil over your water line path are a serious warning sign of a large underground break eroding the soil around it.
If you've lost all water pressure or see major yard flooding — shut off your main water valve immediately.
Your shut-off valve is typically near your meter at the property line or in a crawl space. Then call us right away: (805) 264-3058.
