Water supply diverter valve

[Codyboy]

Not sure its a diverter valve , no idea what it would be called.
From my well tank I have 1" poly feeding the shop as of right now.
When the house is built I'll probably T off that line to supply the house or just run a separate 1", idk yet.
But I also want to run a 1" to the pond to help during drought periods.
Is there a valve that would shut off the pond line if water is flowing to the house?
If the pond is filling and I need to take a shower I don't want to be competing with the flow to the pond.

I don't know of a valve that would do this that is mechanical. To keep it simple, why not put a restrictor on the flow to the pond? I assume there is an on/off float at the pond. You just restrict it enough that it doesn't impact volume/pressure to the house.

Look at 3-way ball valves. You can get them with the ball drilled in an L with all three ports the same size (full or standard port), or the cross drill in a smaller diameter.

Yes the pond will have some sort of ballcock/float type valve. Haven't researched that yet.

Would a 3 way valve be automatic or just manually operated?

I would need something automatic that gives priority to the house.
Perhaps I could use a timer on a valve and only run the pond in the middle of the night when only a toilet or small loads at the house would be needed.
During the day shut off the pond for showering , clothes washing etc.

That's dead easy, you just use a sprinkler controller, which has an electronic valve and timer, just needs some power.

Thinking about it, you've got a well pump, so the last thing you want is to be turning that pump on and off all the time due to a small flow of water... I think I like the timer deal better.

Looks like something a Backflow Preventer would handle nicely.

to do it electrically you could use a flow switch on the house line connected to a water solenoid valve like an irrigation valve . when there's water flowing to the house supply the pond line is electrically closed

All of this would be after the pressure tank so the pump will only turn on when pressure drops to 45 psi.

After further thinking , what if instead of a 3 way solenoid valve I used a 2way solenoid valve on the pond and had a flow device connected to the house line?
Flow detected for the house line would shut off the 2way feeding the pond.
Coming out of the tank I have a manifold I built and can add on to if needed.

Ah. I always forget to refresh to see new posts.
Yes I was thinking the same.

Not sure i understand how that would work to divert or stop flow.
But yes a backflow preventer / check valve would be installed on the pond line to eliminate the possibility of pond water coming back into the system.

Yea, I've got the same setup, but if you're "slowly" bleeding water it's a lot of on/off for the pump. That the downside of my "restrictor" suggestion. It's probably easier on the pump to be at full flow for the pond (on a sprinkler timer) - less on/off.

After further thinking , what if instead of a 3 way solenoid valve I used a 2way solenoid valve on the pond and had a flow device connected to the house line?

I think you're saying a 2-way valve that has an on/off solenoid triggered by flow to the house. Yea, that would work, but it's complicated. The flow devices I've used (water softeners) are have a little turbine in there and like anything mechanical, they fail. You'd need to figure out how to rig that up to a relay or sprinkler system control (which is possible).

Not sure i understand how that would work to divert or stop flow.

You're correct. A back-flow preventer won't solve this.

This is a link to electric operated 3 -way 1" valve. The only issue is these are standard port size (which means the ports could be smaller than 1"), "full port" would be better. You can get different voltages on the coil, 12 or 24v,110.220 , low voltage would be safer and easier to run electric to it.

1" Motorized Ball Valve

Our 1” motorized ball valves come with the reliability and sturdiness you would expect with slightly larger valve. We have seen these used in a myriad of applications, from wakeboard boats to fire trucks. Their consistency, water resistance, and reliability make them a great choice for your project.

A pressure tank on the line to the house line would be needed, as explained a back flow preventer would be needed
