"Tim the plumber on the job was on time and very professional.  He looked at the problem (roots blocking the storm drain) and spent several hours drilling out a clear waterway to the main line in the street.  He indicated that a more thorough cleaning through power blasting would be necessary to get it running through a larger opening and that the roots of the tree in the front of the house may have disrupted the clay pipes.  We scheduled the power cleaning for the following week.  He offered discounts with the purchase of a protection plan which reduces the service call charges and provides additional discounts on work in the future and since I just bought the house and know I have more jobs that will need to be done in the next year I took advantage of the deal.

"Bath Planet came out and remodeled my Bathroom Shower, they were professional, and they did this with in 4 hours, they cleaned up after themselves. We had odd shaped walls but they handled this professionally. Mike the installer was professional, but he did a quality job, he also run into a little plumbing problems, so I had to get my own plumber there to help them out, otherwise everything was good. I am happy so far, it is been 2 weeks of using my new shower and so far so good, very easy cleanup, just wipe down which I Love!!"

"Previous occupants of the house were flushing anything and everything down the pipes. A broken riser was the result from 4 failed attempts at snaking done by other plumbers, whom I do not wish to shame. I finally called the right guys, with the right tools and knowledge to take care of the problem once and for all. They were efficient and very professional. They thanked me for allowing them to do my plumbing even. Just call them and skip the giant headache. Their prices are fair and completely justified. Or call to book a quote! Thank me later."

"The company did the work 4 years ago and it has gone well. We have a very wet basement and the problem 99% gone and when a minor issue pops up they are very responsive and fix the issue. They had to come out twice last week and showed up the day I called. The first time they fixed a switch on a back up sump pump and the second time was to fix and issue cause by another plumber. Josh, who came to our home, was a great help."

"The project involved plumbing and carpentry. They removed the old shower and built up to fit the new shower. FANTASTIC SKILLS! They had everything they needed, were friendly, efficient, and neat. This is my 2nd install with BathFitters and I cannot recommend them enough! If I had another bath, I'd hire them again ;-)"

Plumbing FAQs, answered by experts

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.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

Your local town or municipality’s fire code and other applicable ordinances will set out the requirements for installing and maintaining a private fire hydrant. These rules can vary from place to place, so it’s crucial to consult with your town’s fire or code enforcement departments before you install a private hydrant on any property you own. Alternatively, you can hire a professional fire service consultant to help you interpret local laws and ensure you’re fully compliant with those requirements.

Leaks, clogged drains, cracked basins, and worn-out seals are common problems that may require professional repair.

A hose bib is typically located on an exterior wall of the home, about 6 to 18 inches from the ground or on a deck floor. It will have a top handle that you use to turn the water supply on and off. It will also have a male hose thread, or MHT, on the outlet side, where you would connect a hose.
