I have JCC equipment. My high alkaline presoak gets drawn out of a drum and into a tank where a hydrominder mixes it with water. The hoses that I have been using to draw the chemical out of the tank are clear poly (pvc) hoses (1/2" ID)from Dultmeier. The hoses turn hard and black after several months and then start leaking. They get so hard that the foot valve will not even come out of the hose on the drum end, and on the hydrominder end I can actually break them in half like a pretzel stick. The presoak mixture is heated, so I suspect that the combination of presoak and heated tank are affecting these hoses big time. Is there any other kind of hose that will stand up the the high alkaline chemicals without deteriorating? Or do I have to keep changing them every 6 months?
