How can I install a float switch on these containers?

Hi y'all,

I got these containers from a friend several weeks ago.
I would like to use them for auto water changer. Do I need to use something like a uni-seal to install a float valve?

The container - approximately 40 gallon capacity ea.:

Float valve

The float valve has a seal on it like a bulkhead, keep that on the wet side. That should be enough, just drill in the side of the container at the aprox max level you want then install from the inside. Easy peasy

Agree, this is about the only way of doing it. The only concern I have is the curve of the container. They do make special bulkheads for curved containers that you can get. You may need extra gasket material to get a good seal.
They make what is called a Uniseal specifically for curved containers you could use. You drill the hole, insert the seal, and slide a PVC pipe through it. Then you would need to add the fittings to attach the float valve.

Relatively speaking the hole you drill for the valve is small enough and the plastic container flexible enough that you will be able to tighten the nut doen enough to seal the valve to the round surface.

Thank you guys!
The next step is to connect and program my Apex DOS for the job.

Mine is ran straight from the rodi with a basic Lowe's valve-switch to manually turn on and off. The day before I get ready to do a water change I just open the valve-switch.

I also added a check valve so I could disconnect and store when not in use

I have the same float valve on a round container. Drill the hole HIGH & set the float to turn off just below it.
No water no leak. OR from the flat extension on the top make the float work on close to a 90 degree angle.

Thank you guys! I need to get busy with this. The tanks have been sitting in my garage for several weeks now.

@Tomoko Schum , how did you solve this? I am faced with the exact same issue. TIA!

 

[Tomoko Schum]

I have not done that yet. Working from home keeps me busy with all sorts of things. I need to do that soon, though.
