Good point. I think you can identify a tank with removable bladder by the flange. Some tanks have a diaphram that was inserted before the two halves were welded together.

The problem with a subjective term such as unacceptable is that what you find as acceptable, I might not. Keep in mind that unacceptable WRT showering, is a more recent phenomenon with the advent of all these water conserving fixtures mandated by agencies that believe wasting water is a crime. Give me an old fashion shower over most of these modern ones any day, especially when you get into the big box store models. If you want a decent shower these days you need to go to a good specialty plumbing supply and deal in the back room like it was some sort of contraband.WhitePine said:In that thread he also makes the claim that if you don't have a CSV, you get unacceptable pressure changes when showering...
LLigetfa said:There are some old school nay sayers that think a pump draws a given amount of amps and that the same pump throttled back by flow restricting would draw the same or more amps. The fact is that the current a pump draws is roughly proportional to the flow rate, so when the pump is flow rate limited, it actually draws less current than when it's moving more GPM. That was what I meant.
You seem more concerned about the overall cost of operation in terms of electricity consumed. In that regard, no, I don't think a CSV regulated pump uses any less electricity overall but I also don't think it uses much more. IMHO, it is a very small price to pay for constant pressure. The alternative would be to build a 200 foot tall water tower.

I have the same feeling about the shower at my relatively new place.
On the other hand, maybe it also puts less strain on the well, which in my case is 450' deep and had been hydro-fracted.
murph said:A tank with a bladder is a pressure tank. No bladder is just a holding tank, which gives you more storage. Takes longer for the pressure to drop, longer to build up. How long depends on your pumps ability to pump and you wells ability to produce.
Not to put too fine a point on it, but if said tank is elevated enough, no pump is required. A 100 foot tall water tower should give you around 40 PSI AGL.WhitePine said:A water storage tank, is open to the atmosphere (vented) and requires at a minimum a downstream pump.
