I requested and received a Geyser Miser from the company for evaluation. I tested it in the same configuration as the Geyser STOP, i. e. in a shrubbery riser with an extension above it. Unlike the...

Since I had not received any responses, I went ahead and ordered a Geyser STOP and tested it. I installed it on a shrubbery riser about 3 inches above ground, with another 18 inches of riser above...

If you have not tried one of the geyser prevention projects, here are links to their websites so you can check them out. I would appreciate any pros and cons you may think of.

I realized that if a shrubbery nozzle gets accidentally cut off by a hedge trimmer and goes undetected, when the sprinklers run the resulting geyser would hit the eave of my house, causing a lot of...

Okay, here is what I did. First, one of the zones had shrubbery risers which are directly piped (no flex pipe) so I had my wife tap the nozzle while I felt the pipes. Though it was subtle, I could...

Gary, thanks for the reply.

It is interesting that you do not dry fit first. Perhaps by "dry fit" you thought I was attempting to fully seat the pipe in the socket to check the fit it will have...

I am making changes to the piping layout of my existing irrigation system. I have come across some existing pieces of 1/2" CL-200 pipe that is not dry fitting into new fittings due to the OD being...

I need to connect a new pipe to an existing buried PVC pipe of a particular zone in my irrigation system. At the point where I need to connect, the pipes for two zones make 90 degree turns, so I can...

I guess one downside is that the pop-up heads go through three times as many cycles so they may wear out sooner.

I saw a video that claims for sandy soil (mine is 85% sand) it is better to run through the irrigation program three times, each time putting down 1/3 of the intended total time for each zone. For...

My guess is that because the nozzle is adjustable, Rain Bird wanted the flange easier to grip so you could pull the stem up and adjust it with the water off if you need to set it to a pattern that...

Doesn't the design of the VAN nozzle allow dirt to get into the spray slot? It also seems the flange is more susceptible to being crushed by a lawnmower wheel. Has anyone found a solution? It looks...

I have changed out some regular Rain Bird nozzles on 1800 series sprayheads with VAN adjustable nozzles. The VAN nozzles do not fully seat into the top of the sprayhead when the water is off. They...

I used clear primer, not purple. I thought the only difference with purple primer was the coloring to allow you to see where you had primed, or to prove that you had primed for areas that have a...

Thanks hj for your reply.

You can see the discoloration in the photo below. It appears that the soil has stained the PVC. The original fittings, as well as the new fittings and pipe, are pure...

I have been reworking my sprinkler system and that has involved cutting into the existing CL 200 PVC pipe to add or change fittings. Two things have come up:

1. One of my re-routings requires that...

All of the irrigation heads shown on the diagram are on the same zone.

The grey/brown pebble-textured area outside the sunroom is landscaped with a patio immediately to the right of the sunroom...

I have completed my first try at tweaking the sprinkler head types, nozzles, and layout to get the system down to below 16GPM and improve distribution. I haven't measured actual pressures at each...

Thanks, Mick, for your thoughtful reply. Yep, I am using city water and pay for every drop.

The irrigation system tees off from my city water meter. I cannot easily measure the pressure or GPM...

I do not know what the head pressure is. This is an existing system I had installed eight years ago and I have simply changed out the rotors, which were all PGP units. Two of the PGP rotors were set...

My lawn spray company told me I needed to replace my Hunter PGP 4" rotors because they were leaking. Indeed, there was water trickling down the side of the riser section on several of the rotors. I...

Thanks, Mick, for the clear description of the procedure. I really appreciate that you took the time to write out the steps in detail.

It actually worked much easier than I thought it would. I...

I want to insert a PVC tee fitting into an existing underground 1/2" CL 200 pipe in my sprinkler system. I cannot move the existing pipe apart to insert the tee. I know I could use a slip repair...

Thanks for the input. I found a sponge spud gasket at ACE hardware that was exactly the same size as the beveled gasket. I have installed it and tightened until the flush valve was firm. No leaks...

Well, for some reason few read this posting and so far nobody has replied. Odd... I guess flush valves aren't as interesting as other toilet items.

I am going to try filling in the chip with JB...
