Built-In Patio Misters


Recommended Posts

Not the most complex from a C4 integration perspective, but thought I'd share my built-in patio mister project.

Basically, I combined a solenoid with a C4 switch, hid all the tubing/works (sucked) and dressed up the nozzles with repurposed stainless trim parts.

Pretty happy with it -- and so is my wife, which is key given my DIY obsession, ha -- hope ya'll like!

Any hardware/install details?

We are going to renovate our backyard and want to do exactly what you did 


Happy (and flattered) to help. Can answer more specific questions, but as a start, below are the parts I used (from memory):

  • 0.4mm low pressure misting nozzles
  • 1/4" polyethylene tubing
  • 3/8" polyethylene tubing
  • SharkBite PTC couplers/splitters (multiple per design)
  • U.S. Solid 3/8" NC 110V solenoid valve
  • Control4 plug-in wireless switch
  • Delta Vero 2" stainless flanges/escutcheons
  • Rubber washers with 1/2" OD (fits in above)

The hardest part was running the tubing through my existing patio roof/beams, which shouldn't be an issue in a reno.

Good luck!

Thanks. I have to plan it out. Did you use a holding tank or straight hook up to a water line? Is the valve just for on/off? Which pump did you use? It seems the misting nozzles do the actual work

  • Straight hook up to a water line, though the one for my steam shower, so I figured a drop from concurrent use would be rare
  • No pump -- mine are at supply level/low pressure. I may try one in the future but, honestly, for 6 nozzles, it seems pretty good
  • And yeah, the valve is just for on and off -- placed it in my conditioned crawl so I could winterize the outdoor segment

It seems like you would be wet or, at least, the wife would not be happy about having a bad hair day.


Well yes, spraying water would make you wet - but misters are a nice way to cool down on a hot day, use realitely limited water/energy - and they always rimind me of a waterfall 'mist' on a hot summer day....

May not fit all, but I for one wouldn't mind setting something like this up if I had the house for it,

@samefredd I am wondering how you use this. Are you using it to keep you cool while on the patio? Does it work well? It seems like you would be wet or, at least, the wife would not be happy about having a bad hair day.

It works great, with the exception of the rare occasion when humidity is literally 100%, in which case it looses effectiveness so I don't bother.

Basically, the water atomizes and via physics drops the temperature of the air (evaporative/adiabatic cooling). The effect is pretty profound -- feels like 10+ degrees -- especially when it's dryer. No water hits the ground in my setup (with a ~10ft ceiling and the nozzles at the perimeter).

I recently added a pressurizing pump to the setup (Arizona Mist 92100 Booster Pump) which made it even better/more powerful.
