QuoteWorking in such close quarters the fumes can be quite overpowering to the point where I've actually gotten a headache, to say nothing of working with the horrible smell.
A season before I changed the sanitation hoses I started using Noflex. Was impressed with how clean and lack of smell in the system. Of course the old, original hose was permeated and need changed. FWIW it's what Peggy Hull recommends.
