My well water eats copper and iron, so when my pressurized loop began leaking I had to look for an alternative to the standard garden hose re-pressurizing (goosing) tools. I'm going to have to limp along until I can get someone out with a flush cart to add leak-stopper and convert to a non-pressurized system. I saw somewhere that it was possible to use some garden sprayers to get reasonable pressure restored in such cases, so I sacrificed a Scotts sprayer to give it a try with some distilled water that won't eat my coax. Prior to re-pressurizing, I had a static pressure of ~4 PSI and 12 PSI with the pump running. I was easily able to pump up a pressure of 25 PSI with the pump running using the Scott's sprayer, showing 17 PSI with the pump off. I didn't want to push it any higher than that, though it's possible the sprayer could handle it. Here's a parts list with links and a photo of the finished product in case it might save someone else some time: Scotts 1 Gallon Sprayer Model 190498 available at Home Depot Anderson Metals 57001-0404 Brass Hose Fitting, Adapter, 1/4" Barb x 1/4" NPT Male Pipe from Amazon MBVM Series Brass Mini Ball Valve, Lever, 1/4" NPT Male x NPT Female from Amazon Anderson Metals Brass Pipe Fitting, 90 Degree Barstock Street Elbow, 1/4" Male Pipe x 1/4" Female Pipe from Amazon Winters STP Series STP003 Brass Gauge Adaptor, 2-3/4 OAL x 1-3/4" x 1/8" Probe from Amazon If you heat the cut end of the sprayer hose in a cup of hot water, it slips right on the 1/4" barb fitting without any drama. I put a little hose clamp on the barb, though I don't know that it is necessary.
