Simple to install, wonder how long it'll last.,

This review is from: Toro 53300 1-Inch Sprinkler System Pressure Vacuum Breaker (Lawn & Patio)
We recently purchased a house that had one of these installed as part of the irrigation system. When we moved in we discovered that it was old and leaking constantly. I installed a new one and now the irrigation system is functional.
Installing it was straightforward and fairly simple. You'll only need an adjustable wrench (a larger one) and some "teflon" tape. If the installation goes smoothly this should take you about 15 minutes or less. The only problem I had during installation was getting the threaded joints to seal. It took me several tries before the connections didn't leak. Even now, there is a very slight leak (an excruciatingly slow drip). I do not know if this is because of the fittings on the valve, or the threaded pipe I was connecting it to. I would caution you--if you unscrew anything--to pay close attention to how the pieces need to be reassembled. Two concerns: First, the valve itself is plastic. All other valves I've seen of this sort are brass, so I wonder how durable this valve will be. Time will tell, I guess. Second, while there was a connection and parts diagram in the box, there were no instructions for actual use. For example, the valve can be "winterized", but I've no clue how to do it because instructions were not provided. I don't know if this is not provided normally, or if I just happened to get one with the instructions missing. Update on 7/2/2009: To answer my question on how long the valve will last, in my case it was only 6 months. I'd downgrade my previous rating if Amazon would let me. I replaced it with a brass PVB purchased at my local irrigation supply store.

This device works fine for my application (residential with plastic pipe), but it does need to be thoroughly bled for winter to avoid freeze damage. Easy to assemble and seal, and there doesn't seem to be much alternative at this price.

consider comparably priced metal valves,

This review is from: Toro 53300 1-Inch Sprinkler System Pressure Vacuum Breaker (Lawn & Patio)
I used this valve for a sprinkler system in Minnesota and forgot one winter to bleed the valve completely and it cracked.
After ordering the replacement, I was unable to easily install it (it's a long story but lets just say that plumbing is not my strong point). After contacting a plumber to install the new valve, he politely suggested using an all-metal valve in lieu of this plastic one - which would meet code - and it costs the same buying direct from him as I paid for the toro valve.
