Gas Piping for New Homes in San Rafael
We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both available, and CSST is bonded per manufacturer and code requirements. We calculate total BTU load and pipe length so every appliance gets enough pressure even when everything is running together. The system is pressure tested and inspected before the utility sets the meter.

Water Heater and Recirculation Installation in San Rafael, CA
New homes often use tank water heaters in the garage, basement or utility room, or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is much less expensive than retrofitting later. Homes on hard water see scale on fixtures and water heaters, while very soft water can be mildly corrosive to older copper pipe. If treatment makes sense for your water, we suggest planning space for a softener or filter loop at the same time.
Water Heater Installation for New Builds in San Rafael
Selecting and installing the right water heater is essential for any new construction. We provide professional installation of traditional tank-style and tankless water heaters, considering your property's hot water demands and energy efficiency goals. Our plumbers ensure correct sizing, venting, and gas or electrical connections, adhering to all safety regulations for new homes in San Rafael.
Rough-In Plumbing Services in San Rafael
The rough-in phase is where the core plumbing system is installed within the walls, floors, and ceilings before drywall.

Our plumbers meticulously plan and execute the rough-in, using high-quality fittings and ensuring all pipes are properly secured and leak-tested before inspection.

Frequently Asked Questions About New Construction Plumbing in San Rafael
The cost of new construction plumbing in San Rafael, CA varies significantly based on the size of the home, number of bathrooms, complexity of the system, and chosen fixtures.

Yes, our experienced team can assist with the plumbing design and layout for your new home. We work with your architectural plans to improve water flow, drain efficiency, and fixture placement. Our goal is to create a functional, efficient, and code-compliant plumbing system that fits your family's needs.
For new construction, we usually use PEX, or cross-linked polyethylene, for water supply lines due to its flexibility, durability, and resistance to corrosion. For drain, waste, and vent systems, we mostly use PVC piping because it's strong, lightweight, and cost-effective.
For new construction plumbing, we mainly use PEX piping for water supply lines due to its flexibility, durability, and resistance to scale build-up. For drain, waste, and vent systems, we use PVC pipes, which are resistant to corrosion and long-lasting.
We usually use PEX-A for water supply because it handles heat and resists the scale and pinhole problems copper can develop with aggressive or hard water. Drains are usually PVC or ABS, depending on local code and builder preference. Copper is an option for mains or exposed runs when you want it.
Slow drains on a brand new home, gurgling fixtures, sewer odors or a stub-out that ended up under a wall are typical red flags. These usually trace back to poor slope, missing vents or layout errors before the pour. A camera inspection can pinpoint the cause before the problem grows.
Some jurisdictions allow owner-builders to do their own plumbing on a home they will live in, but the work still has to pass every inspection. Under-slab and gas work are the hardest to get right and the most expensive to fix later. Many owner-builders hire us for those phases and finish simpler tasks themselves.
We install a wide range of reputable plumbing fixture brands, including Moen, Kohler, Delta, American Standard, and Toto. We can work with any brand you specify or recommend options that fit your budget and design aesthetic for your new build in San Rafael.
