Have mine hard plumbed to above the HLT, used 3/4 PEX over from a filter, with a ball valve and some brass fittings for a downspout. My setup is three tiered and stationary, so all the plumbing is up in the ceiling and out of the way.
Well I have city water that has a chemical'ish smell/taste. I do have a marine/rv hose I was using. Yesterday I bought a Dupont filter system that is supposed to reduce Chlorine (among other things) and was going to mount it on my brew stand.
I was planning on putting a T Splitter on the inlet side of the filter with a small hose (unfiltered) for cleanup, and the filtered heading to the HLT. I was just going to buy another short RV hose for the output, but then thought maybe there was another idea to avoid having yet another hose hanging around.
