Install · Water HeaterElectric water heater replacement (permit; fill before power)
Many jurisdictions require a permit and inspection for water heater replacement, and some limit who may do it. The critical steps are a new T&P valve and correct discharge pipe, proper water connections, and filling the tank completely before power goes on: powering an empty tank burns out the element almost immediately.
Install · Water HeaterGas water heater replacement (BLOCKED: refer to a licensed plumber / gas installer)
Replacing a gas water heater involves the gas connection, flue venting and combustion air, which are licensed work. The handyman role is to assess, take immediate safety action and refer.
Install · Water HeaterThermal expansion tank install
An expansion tank absorbs the water that expands as the heater warms it. Set the tank air pre-charge to match the home static water pressure (or the PRV setting) before installing, then mount it on the cold supply to the heater and support its weight.
