Rainbird sprinkler timer replacement

OK Maybe I was confused.
Didn't you originally want to use the old transformer in the cabinet?

If you have a new one in the kit. I would also say it is the safest to use the new one.

Yes i want to use the old transformer as it is neatly contained within the enclosure. Using the new transformer along with the tw523 would be an ugly install. I have to figure out how to neatly install everything in the old enclosure (these weatherproof enclosures are expensive! trying to save money!)

Well if you have a meter and can confirm you get 24.5 volts AC between the Yellow and Blue wire and no voltage between any of the three Yellow; Blue or Red to ground or the mounting frame. It may work.

Yes weather proof or weather resistant and cost seem to go hand in hand.

The old transformer in the rainbird enclosure tested out fine. here is a pic of the install:

Very good.
Thanks for showing us the finished project.

I am hoping you guys know more about sprinklers than I do.

I emailed Warren saying that the valve #4 (backyard) does not shutoff at the scheduled time. It even continues to stay on past the 15 minute kill time that I programmed into the Rain8II. Using my XTBM I've found that the StatusOff for Valve #4 is OFF so it is not the Rain8II.

When it stays on, I've had to shutoff the manual water supply valve. I am thinking this new cheap (~$15) valve has gone bad already as it fails to close. Recently I noticed there was some flooding in the backyard and found a leak in the pipes near a sprinkler head (I have yet to fix). Would the leak in the pipes cause a loss of back pressure which would prevent the valve #4 from closing?


EDIT: I figured it out. It seems these valves do need a certain amount of pressure to close. I fixed the leak..it was just a cracked riser luckily. I also adjusted the flow pressure at the valve and everything worked perfectly tonight. So I am going to assume it is fixed.
