Sheeping? A new supplier in TX?
Never heard of them.
Thanks for all the help, I believe I have the plans all worked out.
I'll take pics when I am done.
post your schematic, and we will appraise it
Ditto, what a confusing thread.
Another way of saying Eweing.
Having done a ton of these types of systems, there is something in the back of my pea brain that bothers the hell out of me, but I can't put my finger on it. I would most certainly be on the drawing board (if you guys even have those anymore) to get the well flow, the transfer to potable, the demand of irrigation and the type of re-injection pumps, float switches and such. Something is wrong in Denmark, or I'm old and in the way.
not that I want to add complexities, but I think there might be a way to duplicate the effect of a pressure-sustaining valve without the expense ~ what is the flow of the existing well output?
Would be my first question. Depending on the demand of the irrigation system, the potable is moot, unless it has a huge demand, in which case the variables will have to be taken into consideration. How do I know? I've run cisterns out when too many folk were in the shower and the irrigation was on at the same time and the cistern re-charge was not properly figured. I learned.
What I'm thinking of, is a variation of the cheapo alternative to a specialty valve used to prevent head blowouts on golf courses. The workaround there was to parallel a small valve to the big one, and use it to evacuate air from the lines, before opening the full-size zone valve.
If you used two paralleled valves to fill the irrigation tank, with staggered pressure-switch settings, the smaller one could work for lower well pressures, so as to not compete with domestic use, and another valve could open at a higher well pressure, for a faster fill.
