Mountainaire 14 Report post Posted November 17, 2006 I've got a 4gpm, 4,000 psi cold pw that I've always hooked to the fawcet and let 'er rip. I'm looking at a job that won't have water available close by and want to avoid the pressure drop from running too much hose. I've got a water tank available to use but am not sure how to go about this. My unloader apparently needs positive water pressure in order for things to work. Can I go with another unloader? If so, what type do you recommend? Or, is there another way to make this work. Also, the feed will be 2 inch at the tank. How do I reduce this to a common hose fitting in order to connect? Thanks.

Curb Appeal 14 Report post Posted November 20, 2006 I just went through the process of plumbing a new tank. Here it goes from the tank: 2" outlet from tank reduced to 1/2" fpt (I got mine from a local PVC pipe sullpy house. I used a couple of different pieces) 1/2" mpt x 3/4" hose barb 15' of 3/4" ID polybraid hose to pump another 1/2" mpt x 3/4" hose barb into a clear bowl inlet filter into a 1/2" hex nipple into a 1/2" 90 deg street elbow into a 1/2" female x GHT male coupler into the pump. Does that make sense? One thing to make sure of though is if your pump is direct drive, the water tank outlet has to be higher than the pump inlet so that gravity and the pressure of the water will help force-feed water to the pump. If it's belt or gear driven (like mine), it will suck water from the tank on it's own. My tank is in the bed of my truck 'cause there's no room on my tiny trailer. Here's some pics that may help...
