@Rolf , thank you for your past post!
@Rolf Post - May 2016:
"As far as specifics, here are a few.
I was a landscape contractor for many years and irrigation was a big part of my work.
Irrigation actually requires way more design competence than a potable water system.
- Always loop the lines.
This will keep even pressure throughout the park.
- Use isolation valves to block off sections of park for repairs.
This keeps you from having to shut down the entire park to fix a leak. I am pretty anal about this and actually put in 2 isolation valves 4’ apart. One can fail but two failing is unlikely. I also use at least 2’ of brass pipe on either side of a valve because turning a valve puts LOTS of stress on pipes. Brass can take the stress.
- Bed the lines in sand with a tracer line as was stated above.
Really good advice.
- Allow for all-weather risers in several places in the park.
This will make your life much easier if they are ever needed.
- Use top quality parts, especially valves, as the cheap ones will cost you grief and money over time.
I always specified valves made in America or Italy and would never buy anything from China or Thailand. I learned early on that one call back to fix a POS part from China more than erased any extra money I “saved” on buying the garbage in the first place.
- ALWAYS sleeve your pipes where they pass under roads.
This keeps them from breaking when heavy trucks (garbage) pass over them repeatedly.
- Get a qualified engineer to design your system.
I would have no hesitation in designing a system for my park near Youngstown, but then I have years of experience doing this type of work.
- Be on site the entire time the work is being done.
People do better work when someone is watching. The garbage that contractors put in below the ground would amaze you. "
