Don't Forget the Accessories
Of course, you should always be prepared. So as you get ready to make water-related changes for energy efficiency, you should check to see if you need any plumbing adapters or Teflon® tape. The adapters, in particular, will be necessary if you want to convert older ball-type showerarms to accept any of the new water-saving showerheads.
Insulate Your Pipes
Insulate Your Water Heater
Unless your water heater was recently installed or already has insulation with an R-value
of at least 24, you could save 4% to 9% on your water heating costs
by simply adding a water heater blanket or jacket. Of course, if you don't know what insulation level you have, just touch the outside of your tank. If it feels warm, it means you're losing valuable energy. But before you start, read the manufacturer's instructions carefully. In fact, you might want to hire a professional
because of the potential of fire hazard.
Switch to Faucet Aerators
It's a little known fact, but letting your faucet run for 5 minutes uses as much energy as leaving a 60-watt light bulb on for 14 hours. So switch to new faucet aerators to conserve and save. If you're unsure what flow rate you need, it's generally considered that a kitchen faucet only needs a flow rate of 1 to 1.5 gallons per minute and a bathroom faucet only needs a flow rate of .5 to 1.0 gallons per minute
