I'm about to scrap this thing. It's less than a year old, but has a horribly designed aluminum discharge tube held in place by o rings. I have replaced the tube and o rings with proper replacement parts, but it won't stay together more than a day or two. I would like to convert it to a stainless steel braided discharge tube, but the existing fittings are not standard sizes available at the local Home Depot. Any suggestions would be appreciated, thank you!
