"Excellent service. The plumber, Tony, was very friendly and helpful. He went above and beyond to help restoring the plumbing I took apart myself. A thumb up! I will use the service again!"

"My shower faucet starting leaking in between the bathroom walls creating a problem. After being told by 2 other contractors that I needed to replace all pipes leading to the faucets, I sent Diplomat videos of the situation, and Mike showed up the next day with the parts he needed to replace the stems and all new hardware.Everything works excellent and came in at 1/5 the cost of the other 2 Angi recommended plumbers who were clearly out to rip me a new one.Mike and I discussed the downside of hiring contractors,and, being one myself,I had to agree there are some companies out there who don't really care if they ever get repeat customers.From my experience, honesty, word of mouth, and repeat customers are the key to a successful business, and Mike's Diplomat Plumbing has me as a customer for life. Highly recommended, stellar service."

"Can you say you have a favorite plumber? I can. Had these great guys out recently to service the tankless water heater, who also recommended a filter to reduce the necessary descaling intervals (and subsequent expensive filter replacements). Also have had them out to clear sewer and drain lines, both at home and at a church we attended. Always fast, on-time, efficient, and clean. Have recommended to people I care about that are in need of trustworthy experts. No BS, just professionals that know their trade."

Plumbing questions, answered by experts

Yes, you should leave outside faucets dripping in freezing weather to prevent frozen and burst pipes. While a drip doesn't always prevent freezing, ice is less likely to form and there's less pressure in your pipes, meaning they’re less likely to burst. You can also winterize your outdoor faucets, eliminating the need to run a drip.

There are warning signs that your copper pipes may be failing. These include discolored water, decreased water pressure, visible cracks and leaks, built-up green rust, and corrosion. If you know the copper pipes are reaching the end of their life span, consider having them replaced or at least having a professional assess your plumbing system.

Ensure there’s a way to flush out excess water from the generator. There will either be a bin you can pull to dump water down the drain or a simple button if your generator is hooked up to a drainage pipe. 

 Ideally, you’ll want to drain after every shower, but there will be a mark on the generator that shows how much water it can hold. Failing to drain the generator can lead to automatic shut-offs or damage.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

Whether an earthquake gas shut-off valve is required depends on your location and circumstances. Certain cities, states, and even insurance providers mandate them, especially in areas with high seismic activity. In California, for example, while laws vary by county, most jurisdictions require a valve to be installed in newly constructed homes or when a home is sold or renovated. The Los Angeles Municipal Code specifically requires a licensed contractor for installation. Even if not required by law, installing a seismic shut-off valve is a wise safety measure. These devices automatically cut off the flow of gas during an earthquake, which can prevent gas leaks, fires, and explosions. It is recommended to check with your local building department for specific laws regarding installation, permitting, and inspections, and to ensure the valve you install is on your city's list of approved models.
