I have all the pvc gate valves for the overflow drains. I I'm doing a partial hard plumbing to soft plumbing. I thought about braided tubing. But then also I thought vinyl tubing. But I was fixing my washer hose today and thought this might be kind of cool look for a soft plumbing underneath. I don't know what type of hose/tubing it is. It's not a regular hose I've ever seen before. I fo remember eshopps sumps come with the type. For those that soft plumbed you tanks what did you use for tubing?
