Several features of a water heater

We will mention several parts to a water heater. And What are good plumbing questions in summarizes some of the characteristics of water heaters that are typically offered.​

Storage Tank water Heaters 
is the type of water heater that we install staying more with the 30 and 40 gallon water heaters. These water heaters have been around since the beginning of the twentieth century.
​
Temperature and Relief Valve
A 40-gallon tank of heated water has the capacity to grow by more than half a gallon. The extra volume will have nowhere to go if your tank is already at capacity, leading to higher pressure inside the inner system.

The temperature release valve lets this extra pressure out. Each valve has a thermostat submerged in the top six inches of the tank's water.

Earth Quake Straps
In seismic regions where earthquakes are frequent, it is advised by building codes that water heaters be braced to prevent damage.

​The straps should be attached to wood-blocking strips fastened to the next wall to secure the water tank adequately. Fit these blocks up against the water heater using sturdy steel brackets as support.

Bollards or Posts to Protect The Water Heater
These are sometimes installed in the garage area. You should take precautions to guard your water heater against physical damage from your car if you've installed it in your garage.

Bollards can be purchased at any nearby hardware store, typically around 4" in diameter and 36" high. Your bollard needs to be composed of an impact-resistant material and bright enough to be visible from all angles. 

Safety Pans
In enclosed spaces, a strong, heat-resistant drain pan should be positioned beneath the water heater. This will shield your floor from any damage caused by pressure valve runoffs or water heater leaks.
