I have a portable troybilt 2500 psi washer that came with 25 ft. of pressure hose. yesterday i bought another 25 ft. of hose to extend my length to 50 ft. Anyway the soap dispenser works with one hose but not both. I assume its too much length to properly siphon the detergent. Is there any way around this or possible a hand held sprayer that will cover a large area quickly.
