I read this on the list and it was 100% gold for me (or anyone else who lives in a locale that does not freeze):

Get a disposable dust mask and some Vicks Vapor Rub - put some of the vapor rub on the inside of the mask and put it on.

You will not smell anything but the Vicks.

I replaced the head and all plumbing using the white sanitation hose - its the stuff that West Marine sells, but you can get it MUCH cheaper at a Lowe's or Home Depot (which is what I did).

Also, use a heat gun on low to warm up the hose before putting it on the fitting - if you do this it will slide on like a charm.
