Everyone has their preferences, and i prefer to use at least 20gal tanks for residential in my business. i look at wells and systems every day, and I'll never be convinced that a CSV with 20gal tank will cycle just as much as one with a 4.4gal tank. reckon people get the whole family to flush toilets and run house water all without going more than a minute in between? Besides, does the sidekick even run 1 minute during a cycle? 1 gal drawdown tank should already have over 1/2gal in it when the valve kicks in at 50psi, right? and with that dinky tank, as soon as the pump kicks on, it's already made 50 psi immediately, so shouldn't a pump with csv and 1gal drawdown tank only run about 30-40 seconds during a cycle?
Btw, thanks for the sales pitch but I currently have 20-25 csv's on the shelf in my shop right now. I really do use them quite often.
