@deprecated_ii@poa.st @snappler@poa.st there is already air involved in the project, unfortunately
see, last winter all my strawberries died and i think it was from drying out. so we need to keep adding at least some water over the winter, but we also need it not to freeze and burst pipes and fittings and emitters.
therefore, give it a cycle of water and then a cycle of compressed air to blow all the water out. and we keep the valves and the chemical injectors inside where they're safe from freezing.
my complaint about chemical injector size is cause my basement is pretty full and i'll have to get creative to find a place to mount this.

@skylar@misskey.yandere.love @snappler@poa.st interesting. I was imagining this outside okay so here's a goofy idea. have a small chamber teed off the top of the water line with a solenoid valve underneath it. have a metering pump fill that partially, pressurize it with air at like 2 psi higher than your water line pressure, open bottom solenoid valve to let the pressure force it into the water lines. use a check valve to protect the metering pump from the air pressure that seems like it could be extremely compact
