C- Bass, some comments and questions. First off, no your storage tank does not need to be full to generate DI
water. The storage tank is just useful if you have a sink faucet hook-up and allows for storage of the RO
water under enough pressure to give you water when you open the faucet. Remember that the dynamic output of these units is a trickle, so if you wanted a glass of water to drink, without the storage tank, you will have to wait until the unit has generated (dynamically) enough water for you. Hope that clears that up.
Now as to your hook up. Is there anyway you can hook up your unit to any convenient cold water pipe that is also located near to a waste pipe? Remember the under the sink hook-up is only because of the convenience of having both the feed and drain in the same place (and usually the space to place it). If not and your only option is a mobile hook up, then you could simply install a 1/4" Jaco valve on the line and use this to shut off/put on and connect/disconnect your system to the inlet. Ditto for the waste, just in the off chance that there is a back up in the pipe, I would install a valve there as well. These valves are rated for up to approx 230Lbs. of pressure, so it will comfortably hold the standard house pressure of approx 60 PSI. As far as filling your container, be prepared that it fill only at a rate of approx 3.5 GPH
, so depending on how much DI
water you need, I used to run a long piece of 1/4" hose from the output of the DI
cartridge to my collection container and just ckeck it every few hours. Now I have plumbed everything so it is all automatic (see my set up in my gallery). Remember if you are using this on a mobile basis, you will not need or use the faucet or storage tank. Just collect the DI
output directly into your storage container.
Hope this all makes a little sense, if not let me know and I will try to answer any questions you may have. 8)
