Why Customers Choose Marin H2O

Toilet installation work we complete comes with a one-year labor warranty. We also offer same-day and emergency appointments whenever our schedule allows, so you’re not left dealing with a non-functional bathroom any longer than necessary.

Our approach is built on transparency: straightforward assessments, honest pricing, and clear communication from the first call through job completion. Those aren’t just values we list. They’re how we’ve stayed in business in this community for over sixty years.

Toilet Installation Scope: From Single Units to Large Commercial Jobs

Most plumbing companies handle residential replacements without issue. Marin H2O carries the equipment and training for large-scale commercial installations and multi-unit projects. When underground utility work is part of the job, we handle that excavation in-house as well.

All work is completed by our own team or a trusted partner company within our professional network, which includes general contractors and HVAC technicians. That means the toilet installation San Rafael businesses and homeowners need, at any scale, stays coordinated under one roof.

California Toilet Requirements Worth Knowing

California sets clear efficiency standards for any toilet installed today. If you’re planning a replacement, these are the rules that apply:

• CalGreen flush volume cap: All toilets installed in California must not exceed 1.28 gallons per flush, which corresponds to the high-efficiency toilet (HET) standard.
• WaterSense certification: Tank-type toilets must carry EPA WaterSense certification, indicating they meet both efficiency and performance benchmarks.
• Civil Code Section 1101.4 retrofit mandate: If you pull a permit for an addition, alteration, or improvement on a single-family home built on or before January 1, 1994, any noncompliant high-flow toilets in the home must be replaced as part of that work.

These requirements apply whether you’re replacing a single water closet or outfitting an entire commercial property. Our team is familiar with CalGreen code and can help you select fixtures that meet current standards, including ADA-compliant and dual-flush models where needed.

Water Quality and Local Rebate Programs

A toilet replacement is often a good moment to take stock of overall water quality. Hard water and mineral buildup can affect fixture performance over time, so we offer free water analyses alongside our plumbing services. We also install and service water treatment products from Culligan for customers who want to address what’s coming through their pipes.

Two area water districts offer rebate programs for qualifying toilet replacements:

• Marin Water serves San Rafael and much of central and southern Marin County and offers a High-Efficiency Toilet rebate for customers replacing older, high-flow units.
• North Marin Water District serves Novato and offers rebates for both High-Efficiency and Ultra-High-Efficiency Toilets when customers replace pre-1993 toilets.

Rebate amounts and eligibility requirements change, so check directly with your water district for current program details. Installing a WaterSense-certified toilet through Marin H2O may help support rebate eligibility, depending on program requirements.
