The well pump delivers 60 PSI. The line rises 25 feet in elevation. Can I expect reasonable pressure at the far end if only one hose bib is open at a time?\u201d<\/p>\n<h2>Answer:<\/h2>\n<p><strong>Yes, it\u2019s possible \u2014 but expect noticeable pressure loss, especially at 500 feet and 25 feet of elevation gain.<\/strong><\/p>\n<p>Here\u2019s a breakdown of what\u2019s happening:<\/p>\n<ul>\n<li><strong>Starting pressure:<\/strong> 60 PSI at the well pump.<\/li>\n<li><strong>Elevation loss:<\/strong> Every 2.31 feet of rise costs about 1 PSI, so 25 feet = ~11 PSI loss.<\/li>\n<li><strong>Friction loss in pipe:<\/strong> At about 5 gallons per minute (a typical hose flow), 3\/4&#8243; SIDR polyflex loses roughly 4 PSI per 100 feet.<\/li>\n<\/ul>\n<p>So, at 300 feet, that\u2019s around <strong>12 PSI friction loss + 11 PSI elevation = 23 PSI total loss<\/strong>.<br \/>\nStarting from 60 PSI, you\u2019d end up with roughly <strong>37 PSI at the final <a href=\"https:\/\/www.amazon.com\/s?k=hose+bib&amp;hvadid=241658027930&amp;hvdev=c&amp;hvexpln=0&amp;hvlocphy=9058279&amp;hvnetw=g&amp;hvocijid=10470426660067492291--&amp;hvqmt=e&amp;hvrand=10470426660067492291&amp;hvtargid=kwd-95357155&amp;hydadcr=26613_9892212&amp;mcid=3d1bf47d5bb03fdb98828128a119909b&amp;tag=googhydr-20&amp;ref=pd_sl_8xm7ryl7l5_e\">hose bib<\/a><\/strong> \u2014 still very usable.<\/p>\n<p>At 500 feet, the loss climbs to around <strong>20 PSI friction + 11 PSI elevation = 31 PSI total<\/strong>.<br \/>\nThat gives you about <strong>29 PSI at the far end<\/strong> \u2014 still workable for light garden use, but not ideal for sprinklers or pressure-sensitive irrigation.<\/p>\n<h3>Tips to Improve Performance:<\/h3>\n<ul>\n<li><strong>Use 1\u201d polyflex<\/strong> for the first 200\u2013300 feet, then reduce to 3\/4\u201d. This lowers friction dramatically.<\/li>\n<li><strong>Install pressure regulators<\/strong> at each hose bib to prevent sudden surges when closing valves.<\/li>\n<li><strong>Avoid unnecessary fittings<\/strong> or tight bends \u2014 each adds extra friction loss.<\/li>\n<li><strong>Check well pump output:<\/strong> A booster pump or small inline booster can maintain stable pressure at long runs.<\/li>\n<\/ul>\n<p><strong>Bottom line:<\/strong> For a single-hose setup, you\u2019re fine up to about 400 feet with usable pressure.
