Newbie with questions.
Hello I am a newbie that has a few questions that are probably fairly easy to answer for the experience person.
1. The main line running from my house to the valve box is a 1 inch PVC line. For some reason the PVC line is at decline so the valves/manifold are probably angle down about 20 degrees. This causes them to be in the ground very deep and as a result the box does not provide good coverage. Can I cut the pvc and attach an 22.5 elbow or two 45 degree elbow to make the manifolds a better location or does adding bends mess up the water pressure.
2. I want to run a new zone to a garden I have. I have one space to install a valve which seems rather straight forward. Is there a valve recommendation? It looks like the other main lines are 1" poly. Can I use the same 1" poly to run 45' to my garden and then install a couple of rotors? Does the line size need to be decreased when I get to the rotors?
Thank you
Lenny
it would be easier to fit another, larger, deeper, box over the existing valve layout.
The problem is there is dirt upto the manifold so regardless I'm going to remove to dig underneath a little further and put some gravel underneath.
Altering the plumbing so you can dig away some dirt is unnecessary. Use a shop vac.
Dirt can fill a valve box to the brim, with the aid of rodents who make a home for themselves. That dirt gets dealt with without doing anything to the plumbing.
