I am currently in the plumbing phase of my 95 gal corner aquarium. I am shopping for plumbing materials and have found a big price variation on ball valves. For example, Hayward brand tru union ball valves run about 80$ for a 1.25" unit whereas the ones at the local Loews plumbing section run about 18$. Is the extra money for the added features in the "better brand" worth it over the long haul? Any help would be appreciated.
