I just moved into my girlfriend’s house and it’s my first time encountering a set up like this. Can anyone give any advice on how to hook up an air compressor to this backflow set up? Attached are pictures of the backflow, along with the sprinkler system components underground. Turned off the upper faucet that feeds water to the system from the house, but past that I’m not sure how to proceed with winterizing. Any help would be appreciated, thank you.

Customer had 'some guy the neighborhood recommended' install a replacement PVB. She luckily had a master valve before it (even if that should've been an iso), so when it popped, it wasn't a constant leak, but all her run times were 30 minutes and she only called us after her lawn died, so it probably was why her water bill was so high. I used the same PVB for replacement after inspecting it for any issues, just replacing the PVC/legs (all the way down to ground for good measure), but that's not exactly the right glue for PVC lol. Please don't use CPVC glue on PVC, especially not on the backflow preventer!

Aloha from Maui,

I have a tropical plant garden I'm putting some drip lines in and had a question about layout. The garden is about 30ft long and 6 ft in depth and butts up against a fence. I have a 1/2 supply line running against the fence at the back of the planter.

I'd like to have a valve to some parts of the garden as some parts need less water than others.

Should I run 1/4 off this supply line? Or should I place a T in the supply line every 10 feet with a short length of supply line which has the 1/4 lines connected to that? A valve would be at the beginning of each of these supply line spurs to control flow.

I have a surface pump that supplies well water to my sprinkler system. I’m looking for suggestions on the size of air compressor to use and DIY tips for winterizing both the pump and sprinkler system. The setup has four zones, with about six or seven sprinklers per zone. While there’s plenty of information about blowing out systems in other ways, I can’t find complete guidance specifically for a pump-based sprinkler system.

Hi, I bought a house about 2 years ago and it came with a shallow irrigation well in the backyard. I replaced the head that was crack and the piping coming up from the well. Pump is an old Sears self priming model, it starts and I think sounds like it's running correctly, but I can't seem to get it to pump correctly. I've filled the tank, I can hear the impeller spinning, when I open the hose bib partially air is coming out. Does anyone have any experience getting older wells going? Am I missing something?

Photo in the comments because I accidentally posted without it.

I’ve got a well pump running on a 3 zone timer and distributor that waters my lawn and garden and want to add a separate line to water my trees at different times. Any ideas?

Is it possible for irrigation to cause such a large sinkhole? Soil is soft very deep, can push this rake in almost 3 feet. Inside is a cavern that I'm surprised has not collapsed. There is no leak when irrigation is off based on my water meter which detects even a minor leak. This sinkhole is located around 10 ft downhill from valve box. I'm scared to run irrigation lines to check in case it makes it even worse. What is the best course of action?
