Retention Tank Options

[ChrisCCCC]

Hello.

I am wanting to install a water retention tank as an emergency water supply on my well system. If my pump fails, I can drain the potable water from the tank directly. Wanting to integrate the tank to the end of my treatment system, and flows into the house to ensure the water in the tank constantly gets replaced, and not stagnant. Attached an image for reference.

Looking at a tank like this:

Flexlite Contact Tank 120 gallons

Buy the Flexlite FLU120EZ Contact Tank 120-gallon model from Water eStore and enjoy a fair price and free shipping all throughout Canada plus benefits.

Does this plan make sense? . Thank you in advance.

I am not a plumber but I think that is a viable option as long as it is potable. Need a vacuum breaker. Your emergency water source line needs to be very short. Like 6” or less.

Thanks for the feedback. Planning to include a vacuum breaker, and the water in the tank would all be potable.

Why does the emergency line need to be under 6" long? Would a longer line cause too much resistance when I'm draining it by gravity?

Consider running some water out occasionally. There may be sediment, and your big tank is doing double duty collecting that..

Also, that should also take the dead-end / stagnant-water problem that I expect that JoeJee is concerned with.

If the pump dies, and you actually are drawing emergency water, you will want to open a valve/spigot connected to the output of the big tank. That will admit air.

Thank you for the help.
