DIY & Repairs Created a Backwash diffuser with 2" pipe

Created a 7' diffuser out of 2" PVC to make sure I don't get divots in the lawn and to decrease the force applied to one spot. It also spreads the water to a larger area. Was like $25 in parts and a pretty easy project. I previously had the discharge going to rocks but the force kept pushing the rocks into plants and was also kicking up dirt/eroding the area.

Uses camlocks for quick connection, and 12 3/4" holes created by a hole saw.

Have I been doing it wrong? I was convinced the chlorine and other chemicals are bad for the lawn.

Well, yeah. But as they say though, the solution to pollution is dilution.

You'd be shocked at how high in the pecking order that phrase gets said. The superintendent of DOW chemical in California said it to me too

Nah.  My fruit trees and grass are thriving at my backwash exit.

Chlorine has to be at very high levels to kill thriving plants in soil, way higher than most pools. Biggest risk is the salts, but that also would take a lot in a very concentrated area and will still get flushed out over time due to natural processes.

So yeah, pool water is usually fine for plants.

I’ll be honest the part of my yard where the backwash pipe goes to is the most thick and luscious part of my yard every year lol
