"While I was painting behind my stove I bent down next to the gas line and actually felt air blowing from a hole in the line onto my cheek--but the air was natural gas. I knew I had smelled some gas, but I kept assuming it was the pilot light. Nope, it was a huge leak in the gas line. No wonder I felt light-headed. I called So Cal Gas to come check it out and their tech replaced the line, but when he tested the pressure on the gas line in the whole house there was still a significant leak. Yikes. The gas company shut off the gas to the entire house, so no cooking, no hot water for showers or laundry. I called another different plumbing company who charged $99 to do an initial visit--wherein they wanted me to sign paperwork for a $600 test of the gas line--but on the first visit they didn't do any work, so I would need to schedule another appointment for a few days later for the gas line test. More cold showers for me. I was informed that if they would cap all of the appliances, then if the line was still leaking, all the horizontal lines would need to be replaced which would be about $9,000, then if that didn't work, all the vertical lines would be replaced for about another $2,000. So upwards of $11k. I asked around and everyone told me they thought that was too high, so I started looking and I found good reviews on Angi for Andy Castillo Plumbing. Their technician, Gus, came out the next day, and immediately went to work. Their gas line test was about $300--so HALF what the other company was charging, and there was no $99 initial visit fee. Gus replaced all five of the interior gas lines and old valves to see if that would hold pressure (and to bring the lines up to code, which they definitely were not). IT WORKED!! Instead of spending $11,000, the entire job cost about $900. Gus checked the line for pressure multiple times to make sure it was holding, then he did it again in front of me, so I could see that it had been repaired. When the gas company inspectors came, they said the line was solid, and they restored my gas!! The entire time Gus was there, he explained everything he was doing and why he was doing it, in clear terms. When I asked him how much it might be if he needed to replace all the gas lines (if the pressure didn't hold), he told me it would be around $3,000--which is almost A QUARTER of what the other company would have charged for the same service. My old plumber retired and I've been looking for someone reliable, honest and skilled to do periodic work on my 110 year old house--and now I found him. Gus is amazing, this company has honest, kind, clear, skilled plumbers, and they are now my new plumbers! (and there have been about four other companies I tried before them for other plumbing jobs, so I don't say that lightly.)"

FAQs for lawn irrigation projects in Walnut, CA

While watering your lawn by hand might save you money upfront, installing and using a lawn irrigation system does save you money over time. You are less likely to overwater your lawn with a professional irrigation system, which will cause a reduction in water usage. These systems use the right amount of water without waste. In addition, watering your lawn the correct amount will also help prevent different fungi from growing, saving you money in fungi removal costs.

Lawn irrigation is the process of getting water to your lawn, grass and all, for it to grow. There are five main types of lawn irrigation methods:

  • Manual irrigation puts you in charge of the flow of water. Using a sprinkler head on your hose is best to evenly distribute the water across your entire lawn. This doesn’t take much time but requires you to be physically outside holding the hose. 

  • Above-ground sprinklers attach to your hose and rotate or oscillate around your lawn. Since these are above-ground, they’ll need to be moved when it’s time to mow, and depending on the size of your property, you might need to move it around your yard for full coverage. 

  • In-ground sprinklers are flush with the ground when not in use but pop up above the ground level when it's time to water the lawn. Piping for these sprinklers is all found underground, and there are different types of sprinkler heads for different uses and lawn sizes. 

  • Drip irrigation involves drip lines that are more efficient than sprinklers for more extensive lawns. This involves a lot of digging since they are installed underground, but it makes it easy for you to mow.

  • Rainwater collection and irrigation uses nature’s precipitation to water your lawn. This option might not be available in every area since semi-reliable rainfall is needed, though the barrels for this system can range from 15 gallons to 10,000 gallons or more.

Even though having a lawn irrigation system to water your lawn is efficient, you do not want to run it daily. It’s best to run your system two to three times a week. The length of time to run your system varies on factors like wind, temperature, and the variety of your grass, but 10 to 20 minutes each time is generally preferred. If you water too frequently, you’ll drown your grass and plants.

The cost of a lawn sprinkler system is $2,550 for the average homeowner. However, this price can range from $350 to $5,000 or more, depending on the type of sprinkler system you install, the size of your yard, and the type of sprinkler heads you choose. For example, rotating or oscillating sprinkler heads are more expensive than stationary ones, making the cost for one sprinkler head $2.50 to $30 each. Likewise, a yard that is 1/4 of an acre in size averages a total average price of $2,460; however, a one-acre yard averages a cost of $9,840.

The total time it takes to install a lawn irrigation system is roughly one to two days. This includes digging trenches for any necessary underground piping, placing the piping, wiring, sprinkler heads, and valves, and connecting your sprinkler system to your water supply. If you have a lawn larger than one acre, or if there are any municipality regulations that extend the project, you can expect the timeline to be closer to two days.
