Reddit reviews DIGITEN DC 12V 1/4" Inlet Feed Water Solenoid Valve Quick Connect N/C normally Closed

It's actually super easy. Bought everything off amazon.

• ice line kit, attach to your water line under sink
  
  
• Solenoid Valve 1/4", splice 12v plug and into a timer or wifi timer.
  
  
• Attach water line inlet to tank
  
  
• Drill hole in tank or use overflow box for water outlet. I made my own
  
  
• Optional, get water filter if your water is chlorinated, check valve for safety, 1 gph drip emitter for better flow control.
  
  I'll make a full guide later

You're may be paying many times more sourcing "locally" if you can't wait until chinese new year is over next month. On amazon anything that is 'prime' should be warehoused stateside


Search for water solenoid example
Compatible diameter tube for above example
and any relay board example.

Moisture sensors are literality just wires shoved into the soil. But beware of electrolyses degrading the metal, you can used galvanized nails or even pencil lead (carbon rods) instead

You shouldn't need a pump unless using a reservoir, but just in case 12V water pump example--note this has a bigger diameter hose connector you may be able to just shove a 1/4" inside and glue around for seal but look around at the different search results for matching hose diameters all around or possible legit adaptors


And don't forget the 12V power adaptor capable of powerint all that. ~2+A should be fine example

I think solenoid valve is indeed the way to go.

You could hook up something like this Amazon link to a relay and a 12v power supply. I guess that particular one gets hot if you power the solenoid continuously for hours at a time, so it might not be the best for you project.

The minimum pressure for this valve is 15 psi. I am running my drip irrigation out of my rain barrel, with a pond pump. It doesn't make enough pressure to actuate the pilot in this valve.

I have tried the following valves, that only require 3 psi and they work. I wish there was better option that didn't require a minimum presure.

1/4" push in compression fittings.

I don't like the dash button idea. I do actually have those setup, but the delays involved would add uncertainty about time.

I found this solenoid, so that could work maybe, but Id have to hard a timer somehow. DIGITEN DC 12V 1/4" Inlet Feed Water Solenoid Valve Quick Connect N/C normall... https://www.amazon.com/dp/B016MP1HX0/ref=cm_sw_r_tw_dp_x_aqIczbQ7W75MF via @amazon

Can’t help you with programming but you could eliminate the pump and use gravity feed and a valve like this

Wow Thanks for the descriptive response!


I'm not very great at electronics, but here is the exact switch I'm using.

As for power source, I'm probably going to use 110 VAC to power the 4 ch relay board. http://www.amazon.com/SainSmart-101-70-101-4-Channel-Relay-Module/dp/B0057OC5O8

This is the solenoid I will be using


Thanks! Your post really helped me think it through. Just need to put it to work lol.

This might be the ticket, because with that type of tubing, I think you want quick connects. I'm not sure about the pressure rating, or if it would be easy to connect to an Arduino.
