"Very well. It is an old house with no straight walls. Craig worked diligently to make sure the bath walls we purchased fit and were plumb. The floor was also a challenge being uneven which Craig did very well addressing it. He used various techniques to level the floor and place the new tile. Very easy to work with and he had good solutions to the problems he faced. He always checked with us to be sure his actions met our expectations."

Plumbing FAQs, answered by experts

The Thanksgiving holiday period is one of the busiest times of the year for plumbers. Both Thanksgiving Day and the day after, often called Black Friday or "Brown Friday" by plumbing professionals, see a significant increase in service requests. This is because a house full of guests, large holiday meals, and unfamiliarity with the home's plumbing can lead to clogged drains, garbage disposal issues, and sewer line backups. Outside of the holidays, the busiest weekdays for plumbers are typically Monday and Tuesday, as many people discover plumbing problems over the weekend but wait to call for service. Despite the holiday, you can rest assured that many plumbers work on Thanksgiving and Black Friday to handle the surge in emergency calls.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

Yes, a sprinkler system can leak even when it is turned off. This issue is often caused by a leaky valve, which may have a crack or hole that allows water to pass through. In many cases, repairing the valve will solve the problem. Another possibility is that water is simply finishing its draining cycle, which you might notice at the lowest sprinkler head as gravity pulls the remaining water out. More seriously, the leak could be due to improper grading of the system, which can lead to significant water waste. It's also possible that what appears to be a leak is actually just poor drainage in your yard. If you suspect a leak, it's a good idea to have a professional take a look to diagnose the exact cause.

The design of freeze-proof faucets ensures that the water in your outdoor spigot properly drains from the pipe to avoid freezing. These designs keep the outdoor spigot pipe from bursting and protect you from related plumbing repair costs, such as ice building up in connecting pipes and water damage in the area around the pipe.

Yes, you can technically use a utility knife or straight blade to cut through PEX pipe. However, this isn't an ideal method simply because you won't get the same clean cut that you'll get with a pipe cutter. A utility knife will likely create angles that weaken your push connections. If you use a utility knife, score the pipe with the knife along your marked line several times before making your final cut.
