I had a fantastic experience with Apex Plumbing service. From the moment I called, they were responsive, professional, and easy to communicate with. The plumber arrived right on time, quickly diagnosed the issue, and explained everything clearly before getting started. It was determined that the root cause of the problem was a sewer backflow pipe issue, which falls under the responsibility of the HOA. Unfortunately, this led to sewage backing up into my garage and causing damage. The plumber handled the situation efficiently and with great attention to detail. They not only addressed the immediate issue but also ensured everything was clean and in proper working order before leaving. It’s clear they take pride in their work and genuinely care about customer satisfaction. While additional repairs such as drywall replacement, sanitation, and mold treatment are still needed, those are the responsibility of the HOA to address. I really appreciated their honesty and fair pricing—no surprises or unnecessary upselling. It’s such a relief to find a reliable plumber you can trust. I wouldn’t hesitate to recommend them to anyone in need of quality plumbing services!
Sump Pump Service & Installation
When winter rain hits Contra Costa County, a working sump pump is the difference between a dry home and a flooded one. We repair, replace and install pumps and backups.

- Pump runs constantly, cycles on and off, or doesn't turn on at all
- Water in the crawlspace or garage after heavy rain
- No battery backup, so a power outage in a storm means a flood
Sump pump repair and replacement
Float switches, check valves, clogged intakes and worn impellers are common failures. We test the pump, the float and the discharge line and fix what's wrong — or replace the pump if the motor is done. Most sump pumps last 7–10 years.
New sump pump installation
For homes with recurring water in the crawlspace, we install a sump basin, pump and discharge line routed away from the foundation. We size the pump for your water volume and lift height so it keeps up during a storm.
Battery backup systems
Storms knock out power exactly when you need the pump most. A battery backup pump keeps running for hours without electricity. We install and test backups and can add a water alarm so you know before there's a problem.
What's included
- Pump diagnosis & repair
- Float switch & check valve replacement
- New sump systems
- Battery backup pumps
- Discharge line routing
- Pre-storm inspections
Questions about sump pumps
How often should a sump pump be tested?
Pour a bucket of water into the pit a couple of times a year, especially before the rainy season. We offer a quick pre-winter check.
Do I need a battery backup?
If your crawlspace or basement floods when the pump stops, yes — power outages and storms arrive together.

Highly recommend! Nick did a really nice job and for the best price out of four quotes. Will be calling Apex first for my next plumbing project.
Nick and his team were just top notch. We had another national plumbing company quoted us $7K to fix a sub-pump issue, and Nick figured it out in like half an hour, no charge. I’m not kidding. He didn’t even accept a tip— said we should just use APEX again in the future if something needed fixing. Thank you Nick!
Apex plumbing is top notch. I highly recommend them for any plumbing needs you have. I had an issue with an exterior leak and Nick was able to meet me on time and diagnose and fix the issue. Call Nick he will take care of you.
Highly Recommend! We had an outstanding experience with this plumbing company! Nick, the owner, came out to switch a toilet for us and was everything you hope for in a local professional—punctual, friendly, and very fair priced. He took the time to explain exactly why our old toilet wasn’t working properly and even offered helpful suggestions on a few DIY projects my not-so-handy spouse has going on. Nick was incredibly generous with his time, knowledge, and energy. It’s rare to find someone who goes above and beyond simply because they care about doing things right. We’ll absolutely be calling him for any future plumbing needs and recommending him to friends and neighbors. If you’re looking for a trustworthy, knowledgeable plumber, look no further!
Not only did they send someone out right away but the 2 plumbers they sent out went out of their way to assess and take care of our problem, which happened to be a fork stuck in our washing machine drain. Boy did we have a good laugh about that. I would definitely call them again for any future plumbing issues and highly recommend their company.
