I had another shampooer hose split today causing ragged metal near the shampoo head. In the past I have replaced the whole assembly but today I decided to try and fix it by cutting it short and having my local hose guy put a new fitting on it. Spent most of the afternoon trying to fish the poly tubing and wires through with little success. Anyone have any tricks for this. Or, do you know where I can buy an assembly that is reasonably priced. This is crazy what these things cost and how often I seem to be replacing them. About five in five years.
