Frequently Asked Plumbing Questions
How much do plumbing services cost?
Every job is different, so pricing depends on the scope of work, the fixtures involved, and whether it's a straightforward repair or a full installation. We provide upfront pricing before any work begins, so you know the cost before we start. There are no hidden fees or surprise charges added to your final bill.
Do you offer 24 hour emergency plumbing services?
Yes. RAP Plumbing operates 24/7 and responds to emergency plumbing calls throughout Walnut Creek, Concord, Pleasant Hill, Alamo, San Ramon, Lafayette, Pacheco, and Martinez. Burst pipes, gas line leaks, and overflowing drains don't wait for business hours, and neither do we.
What areas does RAP Plumbing serve?
We're based in Walnut Creek, CA and serve as a local plumber throughout the surrounding communities, including Concord, Pleasant Hill, Alamo, San Ramon, Lafayette, Pacheco, and Martinez. If you're unsure whether your address falls within our service area, just give us a call and we'll confirm right away.
Is RAP Plumbing a licensed and insured plumbing company?
Yes. Roberto Plascencia is a licensed plumber with over 10 years of hands-on experience in residential and commercial plumbing services. RAP Plumbing carries full insurance coverage, so every job, from a simple fixture repair to new construction plumbing, is handled by a qualified professional with your property's protection in mind.
What is the Moen leak detector, and how does it help with insurance?
The Moen Flo is a smart leak detection system that monitors your water usage and automatically shuts off your water supply if it detects a leak, a burst pipe, or unusual flow, acting as an automatic water shutoff system for your whole home. Many insurance carriers now offer discounts to homeowners who install one through a licensed plumber, since it reduces the risk of costly water damage claims. We handle Moen Flo installation and Moen leak detector installation as a standalone service or as part of a broader plumbing system upgrade.
Do you provide commercial plumbing services for businesses?
Yes. RAP Plumbing works as a commercial plumbing contractor for offices, restaurants, contractors, and tenant improvement projects across the same service area we cover for homeowners. That includes office plumbing, restaurant plumbing, gas line installation, and plumbing for new build construction from the ground up.
Can you repair or replace a water heater the same day?
In most cases, yes. Our water heater services cover repair, replacement, and full water heater installation, and we carry common parts and units so a same-day fix is often possible. We also handle hot water recirculation pump repair and hot water recirculation pump installation for homes that want faster hot water delivery. If your water heater is leaking, not producing hot water, or making unusual noises, call us and we'll get someone out to diagnose it quickly.
Do you handle drain, sewer, and gas line repairs?
Yes. Our drain and sewer services include drain cleaning, drain repair, and sewer repair for clogs, backups, and aging pipes. We also handle gas line repair and gas line services for leaks, reroutes, or new appliance connections, all performed to code by a licensed plumber.
