All of the plumbing appliances, fixtures, and components in your home are important to your day-to-day productivity.
In fact, having one appliance quit working is extremely inconvenient and disruptive. However, if that one appliance is your water heater - the word inconvenient doesn’t even begin to describe it.
Your water heater is essential not only as an appliance in and of itself - but, it is essential for the proper function of all of the other appliances, fixtures, and systems of your plumbing.
Think about it - if your kitchen sink gets clogged it is very inconvenient. But, if your water heater malfunctions, things like washing dishes, doing laundry, or taking a shower are all pretty much impossible.
