"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

Fire Sprinkler Companies questions, answered by experts

To map your sprinkler system, sketch a rough blueprint of your yard, noting features such as fences, trees, and driveways. Keeping the coverage area of your sprinkler heads in mind, plot them on your map, making sure to space them so that there’s a bit of overlap (this keeps dry patches at bay). Some companies provide design services that will help you account for your particular water flow and pressure needs so that the farthest sprinklers still have enough pressure to do the job.

Most jurisdictions legally require a backflow preventer on your drip irrigation system. Even if you live in a place with less strict laws, installing one is a great idea. If you’re planning to use fertilizers or other chemical additives in your garden, a backflow preventer helps ensure those substances stay outside of your home’s water supply. Depending on the complexity of your irrigation system, you may be able to install one for under $100.

Determining the number of zones for your HVAC zoning system depends on your home's layout and comfort priorities. Consider spaces with similar usage patterns and temperature preferences. Larger homes may require more zones for effective control, while smaller ones could do with fewer. Assess your family's needs, and consult a professional if you’re unsure, which will ensure a tailored and efficient HVAC solution.

Yes, systems can integrate weather data for automated adjustments and water savings.

You can find irrigation lines whether you dig or not. If you decide to dig, do so near valve boxes and around sprinkler heads. Once you find the first pipe, you can map the system from there and use spray paint or tape to mark the pipe layout throughout.  

If you don’t feel like digging, aside from getting a map from the maker of the irrigation system, you can still find irrigation lines by locating the valve box and following a line back to the head sprinklers. You can also use a water-detection device or a metal detector, which will work if the lines have metal tracer wires.
