Yeah that was my concern initially, the time it would take to get the 35-45 gallons of water my system will hold. I think if I can make the space, I'll get a 50 gallon barrel and a seperate pump. My systems plumbing isn't something I want to mess with anymore. I just got it finished up today. Running a line to my bathroom isn't an issue. I just don't wanna mess with my complicated manifold I cobbled together. A seperate submersible and a hose would to the trick when the time comes.
On to the next hurdle, I guess. On a positive note, I "finished" my first RDWC project today and got the electrical roughed in. Looks like getting the RO set up will put me back a week or two but I'm creeping towards the end of setup and I'm getting antsy.
