Have you ever:
Aquanta can be installed by a "handy DIYer," meaning that if you are comfortable replacing a faucet, putting in Aquanta will be a snap. Aquanta is designed for use in tank storage-style water heaters – like those found everywhere in the US and in many parts of the world. It works in tanks holding 120 gallons and less, although will not work with tankless or "on-demand" water heaters. Your tank needs to have a 3/4" port (which is near-universal in US tanks) into which Aquanta's sensor gets installed.
