Short runs
« on: May 26, 2021, 11:52:52 PM »
Thanks for all the detailed explanations on your site and this forum. I can see how CSVs would help with long runs of water. But how do they fare when the usage pattern is more short bursts of water, with few long runs?

Our well just feeds our RV. So we don't have a sprinkler system, bathtubs to fill, etc. Even our toilets don't have a tank to refill (just press the pedal and water comes on for a few seconds). Only our morning shower draws water longer (and even then we're pretty frugal with water).
In this scenario (mostly short runs of water), would the CSV (with a small tank) still offer benefits or could it even be detrimental? Wouldn't it turn the pump on and off each time we turn on the water briefly, therefore causing the frequent on/off cycling we're trying to avoid?

If I do decide to use a CSV, would the 10gal tank rather than the 4.5gal be a good idea to mitigate this?

Here is a chart to show the number of cycles per day using the small tank and CSV is the same as when using a large tank with no CSV, even when used just for a house.  of course there is even more benefits from the CSV for systems that use water for long periods of time like irrigation and heat pumps.  But there is no reason for a lightly used house only system not to have the same constant pressure and ability to use a small pressure tank as more heavily used water systems.  The many other benefits of the CSV is why it takes an entire web page to explain it. :)
