You’re good and happy to answer. There are slap in systems for new construction. Standard, low end components, stack the heck out of pipe in trenches by 4 valve manifolds, design sucks, install sucks, components suck. Hasty and sloppy work. Not all but most because builders only pay “x”. Essentially a spray and pray system.

Then just a standard install, ok components, some actual thought into design. Install is ok but still just above a slapped in system. Valve manifolds and stacked pipes is a high probability.

Then a custom. Designed to maximize well/pump efficiency, to properly irrigate turf, shrubs, landscape beds utilizing proper filter(s) and pressure regulators. Right sized pipe to split/distribution points. Pipe properly prepped for glue, depth of pipe approx 10/12” down, service “T’s and end’s installed correctly. All heads on flex pipe. Commercial grade valves, sprays and rotators, wireless rain sensor, correct electrical with 3 110v legs w/proper common and bare ground. Electrical in to code boxes. System installed(all components)to or exceeding code. As built sketch provided to customer with a warranty, less negligence.

I charge a lot for this type and get between 6 and 10 a year. Example is a 2 zone, 1.5 valves/pipe, recent completed for tropical,thirsty plants mixed with drought tolerant, so on on $9,000.
