Installing a new 50 Gal electric water heater. I'm moving the unit to the back of the room. Do I need to install a vacuum breaker on the cold supply, I've heard yes and I've heard no.
Thanks! There was one on the old line to the water heater but I hadn't seen one before that. After seeing it, I asked around, heard some yeses and some nos. I defer all to your knowledge. Thanks Ron.
The purpose of a vacuum breaker at a water heater is, in the event extreme suction should be applied to the water system, for example a fire engine pumper fighting a fire down the street, the water heater tank doesn't collapse or implode.
They're only about $15. Of course you may need extra fittings which will likely double the cost. I think it's worth the expense. Especially since I believe you can use the same Vacuum Breaker over and over again.
Someone using Google to get plumbing do it yourself help.
