"Boyd Building had done some work for us in the past so when we needed a major deck and porch rebuild and finish, we knew Shawn would be the only one to call. Shawn always goes above and beyond in planning and executing our projects. He once told me that he puts the same amount of quality and care into the work he does on a customer's home as he would on his own home and I truly believe him. His work is detailed and meticulous. The job he did remodeling our outside space is top quality. There is not one thing we had to question. We love everything! Beyond that he is reliable, honest, trustworthy, hardworking and a really nice guy. We can't possibly recommend Boyd Building any higher! 5 stars don't seem like enough! "

Fire Sprinkler Companies questions, answered by experts

Typically, the white wire is the common wire on a sprinkler valve. This makes it easier to identify, and many local electrical codes require the common wire to be white. However, in some places, any wire can be the common wire. If you ever need to call in a pro for repairs, the industry standard is for the white wire to be the common wire. So, if you decide to switch it up, relay that information to the sprinkler specialist before they start working.

Drip irrigations can be anywhere between four to 12 inches deep. In four-season climates, it’s likely that the system is buried under the frost line. The frost line is where the solid freezes in the winter. If your pipe is buried above the freeze line, it’ll freeze and thaw with the weather, making it more likely to crack and break.

A sprinkler system consists of many parts, including a water source, irrigation meter, controller or timer, several types of valves, pipes, risers, sprinkler heads, and sprinkler caps. These parts work together to operate your yard’s sprinkler system, and one of them breaking down or not working properly can cause a problem with the system as a whole. Contact a local sprinkler company for help identifying parts of the sprinkler system in the event of an issue.

You can run 5 to 10 sprinklers on one line, depending on your home’s water pressure and flow rate, and the performance of your sprinkler heads. In some cases, your zone might only be able to support two or three sprinkler heads if they use a lot of water.

Sprinkler lines need to be buried 8 to 12 inches deep. The pipes should be at least 4 inches deep and should be completely underground. If you live in a colder climate, consider burying pipes deeper than 8 inches to better protect them from freezing temperatures. Don’t bury the lines too deep because this can make it harder to detect leaks and make sprinkler repairs.
