Another vote here for the smart buddie pump. I got one a few months ago when i was starting a tank back up, previously when i was running the system i was getting about 30 psi and after the pump im up to 90. Also does a backflush of the membrane every time its powered on or every 24 hours. I cant say for certain if it sped up my water rate, as i changed a bunch of stuff at the same time. Before and after the pump i was making about a 5 gallon bucket an hour, but i also switched to a 99% rejection rate membrane from the standard spectrapure 90%.
