Super Sturdy Pressure Regulator
Drive over a pressure regulator? You bet! See my video to learn which pressure regulator I drove a truck over and it didn’t break. Try that with your existing regulator.
Watch a video demonstration here:
The pressure regulator keeps the pressure below 25 pounds-per-square-inch (psi). With some drip-system parts, an even lower psi is required. Porous hose must be kept below 10 psi so the special fittings don't leak. Good-quality pressure regulators are sold with a specific rating of either 10, 15, 20, or 25-psi . The pressure regulator must always be plumbed in after the filter so that full pressure is available to flush the filter's screen.
