Thanks for the reply. I have one more related question. How about sharing a pressure regulator before a 4-value manifold? Basically, the setup is faucet->backflow preventer->filter->pressure regulator->4 valve manifold.

The valve at the faucet is wide open and the water flow is controlled by the 4 individual values at the manifold. So are the filter and regulator considered to be installed on the "mainline"? I heard from other forum members that it is not recommended to install them on mainline... Can someone give me some advice? FYI, I am using DIG drip components. Thanks.

What I've seen with a similar setup is that the valves (on the 4-valve manifold) leak after a year or so. And the faucet itself can leak. I wouldn't leave the faucet on all the time.

My current setup has the (1) filter (2) pressure regulator ( I got a 'real one' from my local irrigation supply), timer (a Melnor unit) and manifold. I use a 5-port and toggle the desired line/zone. I make damn sure I turn the faucet off after use.

I've used DIG components until the local Home Depot cut way back on shelf space sharply reduced my choices. Except for DIG tubing, I shop exclusively at my Irrigation Supply house.

Hi dirtm,
Sounds like a somewhat inconvenient semi-automatic system. My valves don't leak and it's been 8 years. Check the push-on, threaded and glued connections (wetness around the valve boxes or manifold). Your Irrig. Supply Store should have high-quality items and some advice to go with them. Good luck. Aloha.
