I was thinking the brackets would work best. I don’t really have to worry bout the waste tank, it’s about 39″ + the length of the inlet pipe. The only way those babies are coming out is if I remove the support stud from the base and remove the right side panel. Also would have to remove the far right flange from the sink and remove the drain pipe. I don’t plan on cementing the flanges anyway, just the pipes. I don’t think it will be a problem since I’m using compression fittings on them anyways. I have to redo my supply line runs anyway, I wanted to run 2 individual lines, one for the colds, & one for the hots, branching off of the out post on the water pump. I have a final blueprint of my plumbing now that I have dry fitted everything. I don’t see anything wrong with the runs. I’m sure the water will pull for the hots just the same as it would for the colds. I don’t know much about how on demand stuff works, but I see no reason why it wouldn’t work, but I will post my plumbing runs on here to see if anyone see’s any reason why it wouldn’t work properly.  I also plan on keeping a tool box with some replacement fittings, small container of glue and tools, just in case I need anything on the fly. I have room underneath the sink to keep it there.

Also I’m looking for 90degree suitcase latches for my counter tops. I know they exist, I just can’t seem to find them. I saved a browswer link for them, but when i blew out my pc, i lost it 🙁  LOL
