Gravity-Fed Watering System Finished

A photo of Nebraska DaveWell folks you are probably getting real tired hearing about a gravity-fed watering system. This will be the last post for phase one of the gravity feed watering system, which brings this project to an end for this year. It came on line on August 10th and has performed flawlessly since then. I've discovered that the big tank needs filled every two weeks. This is a picture of the main watering tank with it's patch showing in all it's glory. You can see that two weeks away has definitely allowed the weeds to abound.

Main Watering Tank

The main tank is connected to the secondary tank. The main tank is 1200 gallons and the secondary tank is 30 gallons. The water level in the main tank will fill the secondary tank to the same level. That's the reason the secondary tank is elevated up on blocks. It's to keep the secondary tank from overflowing. I sighted across the main tank with a 2X4 to see where the top of the main tank hit the secondary tank to get the water level right.

Hose Connecting Tanks

The hose connection from the main tank is connected to the secondary tank with PCV valves and hose connections. I discovered that hose threads and pipe threads are different and one will not fit on the other. In the PCV world the hose threads are called MHT and pipe threads are called MPT. It took some time to figure out how to get the right threads in the right place on the system. It was all a learning process with many hours spent at Lowes trying to fit things together.



Of course you have seen the gray box in a previous post which is the heart of the system. It's the programmable timer. Right now during the hot part of the season it's set at 6:00am to turn on for five minutes which will deliver one gallon of water to the root of each plant each every day.

The gravity fed watering system looks great. You'll be good to go for next year's gardening season! Have a great trip!

Cindy, watch out I'm flying without a spell checker so it's hard to tell what will come out of these fingers. My Aunt and I are traveling together and stayed over night in Green River Wyoming. We awoke to a temperature of 37 but by the time we reached Las Vegas it was upper 90s. I left a huge todo list at home. In addition to that my garden is really winding down fast. Even though the watering system is working wonderfully well most everything is drying up. Our first frost is October 15th so I expect that the plants are well aware that there time is limited. Hopefully I can get three more raised beds built before the snow flies. I will definitely want more tomatoes and more bell peppers next year. Cucumbers? Maybe the same but spaced out a little more and not near the tomatoes. The tomato - cucumber battle was ughly. At the beginning of the year the cucumbers ruled the bed but when the tomatoes finally kicked they beat out the cukes. See ya back on the blogs in about two weeks.

MW,Thank you for stopping by. I have just a few moments on my sister's computer. I spent the morning out on the lake behind Hoover Dam fishing with with guys that are from Dad's church. We didn't even get a bite but I'm still excited about the trip to northern Nevada. We are leaving on the Thursday the 16th and returning on the 20th. The temperature was up to 100 yesterday when I visited my grand kids. We ate lunch at Applebee's and stayed inside the rest of the day. See you back on the blogs after the 26th.
