How do I hook up the third hose for water like south east soft wash has there's? So when you switch it back to water it also rinses out the downstream injector. Is there an adaptor I plug two hoses into bleach and water then it goes to one hose to plug into the electric ball valve?

Thanks for the tutorial, but I have an issue, I bought 2 valves, i built the first one following every step, and it worked, the valve opened, but when I turn it off, it doesn’t close.

I'd check how you have the switch wired. If you look closely at the wire colors you can see that the red/white wires from the battery enter the corrugated split tube but when they come out one is red and the other appears to be black. The white wire has "black heat-shrink" tubing on it making it appear to be black but that's the white wire from the batter. Hope that helps

Hi, this would also work for softwashing right, bc this just helps pull chem / Water / Soap right? Thanks

[@williamseith4267]

So this setup would not be a good fit for a softwash system. You need to build a metering valve setup for that because your mix is usually 50% SH and 50% water. That gives you the 6% bleach strength you need to clean roofs. Downstreaming for siding with a 1-2% mix is ok for this system.

[@williamseith4267]

@@iamjacksundyingaddiction6595 I'm not that familiar with the Flowpro which looks like a pretty good product. It also looks like that unit uses an automated DN10 ball value which diverts pressurized water from the pressure washer through the bypass system. I really like that. It's actually a better setup. My system only turns the soap on/off but the flow of water still goes through the downstream valve. All in all that system looks like a pretty good product for the money.

So I don’t need a soft wash system this way

[@businessideasacademy]

So this is a great way to downstream using your pressure washer. This system will allow you to remotely turn your soap on/off. You can achieve the same thing by changing out your nozzles. I like this for downstreaming because I'm sure the soap is off especially when I'm watering down plants or rinsine the SH off a home. I've had rinse nozzles that will still let soap through the system. It might be because of the length of my hose causing a pressure drop across the DS injector allowing soap to flow. So for washing homes... you can consider this a substitute for a soft-wash system. However, it will not work if you plan to do roof washing. You cannot deliver a strong enough SH mix to clean roofs (about 6% SH).

[@williamseith4267]

You are correct. You can use different tips if you're downstreaming but there are more applications for this setup if you're creative. I use a similar setup with a larger 3-way motorized valve to switch my roof pump from SH to water only. Also, I've had my zero orifice rinse tip (the one rated for my 8gpm) pull soap. Not sure why so I added this system for safety. Especially when using to hydrate plants.
