If your running say a 4000psi 4 gal per minute pressure washer and you back the pressure down at the unloader do the gal per minute also drop? The reason i ask is Im putting together a mobile detail rig and i have a 190gallon tank onboard which I am running spotless water and i want to conserve it being the distance i need to drive to fill it up but id like the versatility of the bigger pump to hook up to someones garden hose and wash a drive way or what ever else comes up to make a buck. thanks jim
