    Let me know what I can do differently, and improve, and what you vets think.

    Anyway, old 3/4" atmospheric re piped to 1" PVB piped straight from the water meter, there is a drain in the basement also.

    old 4 zone system.
    Updated to 5 zone system with a 6 valve pvc manifold and 6 pgv's.
    2 zones capped off (back yard) and new 1" lines installed and 6 new pgps for those zones.
    6 new pgps for 2 front zones, and 6 new 4" sprays for front.
    new hunter pro c with 3 station module
    wireless irritrol rain sensor

    If i were to do it over again, I would have done the vb a little differently and placed the valve lower, but it should be ok, more personal preference. I also would have not used that elbow on the bottom that connects to the manifold, but again personal preference.

    Pic 1 is old atmospheric
    pic 2 is new pvb
    pic 3 is old valve set up.
    pic 4 is zone 4 of 5

    I didnt get a pic of the finished valve manifolds or anything of the front, with all the rain there was no time for pics. I will get more pic's tomorrow.

    please critique me as i always am looking for new ways to improve.

    Nice clean job (and this comes from a PVC guy!)

    Wish I could see more backflows with unions installed, especially in areas that freeze.

    Minor points on aesthetics...... wipe down the copper with a wet rag while it is still hot so you don't have those green marks or the black scorch marks. Also hit the solder drips quickly with the torch and wipe them off as well.

    I would have opted for a threaded tee for the boiler drain. And I like 1/4 turn ball valve drains.

    I like the PVB to be about 5 to 6" from the house so the entire device can be removed/replaced easily when it freezes.

    Also, use a cast 90 ell with a drain.

    you should wipe down the joints after they cool, not while hot

    I wipe em with a dry rag while the solder is still flexible.

    Cool temp doesn't help the same as when still a hot temp. And I do not mean wipe with wet rag while the soldered joint is still molten/flexible. But the wet rag should sizzle on the pipe.

    You can "soak up" or knock off any extra blobs of liquid/molten solder with some steel wool. Even wipe it a bit w/o disturbing the joint. It does take a certain "touch" not to disturb the soldered joint. Then wipe with a wet rag WHILE IT IS STILL HOT.

    Started sweating copper 31 years ago, only two leakers. Honest.
