Storage tanks
- Thread starter BROKER
- Start date
My RO system feeds into a sealed tank. As far as I can tell, as the tank fills, it pressurizes, and when the tank pressure reaches the water pressure, it shuts off the filter. I know that larger tanks are available from DIY stores (Lowes, Home Depot, etc.) for my system. Perhaps something of that sort is available for yours?
It may or may not be the cheapest way, but it is probably the easiest and there is probably some sort of warranty protection if the tank fails...
I've never seen a warrantied DIY job.

I bought my RO/DI unit (Kent Maxxim) with a float switch and solenoid valve (sold as an option). The float switch is mounted on/through the side of the storage tank near the top. When the water level rises so as to raise and close the float switch, the backpressure causes the solenoid to shut down the RO/DI unit. It has worked perfectly for the 18 months I have had it.
By the way, the system will work with the float switch only, but without the solenoid, the water will still run through the system.

hi.
As mentioned, there are the bladder tank and the float switch. Some water filter companies (e.g., SpectraPure) sell water level controller, and you can buy them or DIY. Some work by water pressure, some work by light sensor, while some work by sound.
The disadvantage of bladder tank is that the back pressure as the tank is filled make the RO less efficient. Permeate pump help a little, but it may be not worth it if you only use RO infrequently.

Well, I'm one of those guys who sees it as a threat to my manhood when I don't already know the answer, so I NEVER ask for help...
Actually, after we bought the system, I was walking through Lowes one day and saw some tanks that were the same blue color as the one that came with our filter. I walked over and took a look at them, and sure enough, they were different sized tanks of the type I already had...

Once again, I see cwa46 and I coming at things from different directions and getting equally satisfactory results...
I looked at the cost of bladder-type tanks and kent float switches this past weekend. I am inclined to agree that if you already have the tank, the float switch is probably a better solution. The switch is probably a tad more likely to fail than a bladder tank, but not enough that I would be concerned...
After all, your tank bottom has a certain chance of failure as well.
