Why? Quite simply, because we strive for perfection. If you are hoping we will use cheaper materials, hurry through an installation, or overlook restrictions, P.J. Fitzpatrick, LLC, is not the company for you. We believe that when it comes to your home, the job should be done perfectly and last a lifetime. This might not make us the cheapest company in the area, but we stand behind our work and leave our customers extremely satisfied. So much that they refer friends, family and neighbors without hesitation. If something goes wrong with our installation, it's not your fault, it's ours. Our responsibility doesn't end once we pack up our tools and leave. If something breaks, malfunctions, or just plain doesn't make you happy, we'll fix it - for as long as you live in your home. Full lifetime warranties are included with many of our services. We also have 18 Repair Experts who do repairs all day, every day and love it! Experience the P.J. Fitzpatrick, LLC., difference today!

Fire Sprinkler Companies questions, answered by experts

Most homeowners leave their sprinkler timer on at all times—and then the timer turns sprinklers on and off as it’s been programmed to do. As to how long you should run your sprinkler, the answer to that question depends on what types of plants and soil you have, how hot it is where you live, how established your landscaping is, and other factors. However, you can start with 30 minutes, three times per week.

In most cases, the backflow valve is located near your home, where the irrigation system connects to the water supply. (After all, the whole purpose of this valve is to prevent the irrigation water from back-flowing into the potable water source.) If you’re not sure how to find your sprinkler backflow valve, an irrigation or plumbing professional can likely help you.

The main sprinkler valve is usually located in an easy-to-access location close to the house and may include one or two backflow valves that help reduce the risk of water flowing backward toward the source. If you’re still unsure where your main sprinkler valve is located, consult your owner’s manual for full details.

Like anything else, sprinkler pipes will freeze if the temperature falls below freezing, which is 32 degrees Fahrenheit (or 0 degrees Celsius). However, winterizing your sprinkler system is a relatively simple (if somewhat time-consuming and tedious) process, and it can help ensure your system won’t be damaged over the winter, even if it does freeze.

Services include running cables, installing outlets, configuring hardware, and testing the network.
