Having, me, the same Master Plumber, the owner, with my approach to long term relationships is an advantage that some people value. The fact that I also perform any plumbing repair, gas work, appliance replacement, and most drain situations is another significant benefit. Water heater installers install water heaters, period. I have even done a warranty repair, that they would not do. A water heater replacement is one of the largest jobs and best jobs (from a plumber perspective) that any homeowner is likely to need. If you were me, and you had a busy schedule, which customer would you prioritize; the one that always price shops for the low bidder? Or if you needed to make the choice, serve the customer who is loyal and appreciates value?

If your water heater is leaking or dripping water out of the bottom you will need a new water heater (replace the old water heater) This post makes sure that your new water heater fits into the same area as your old one. If you’ve already talked to me on the phone skip to the bottom for the link to the checklist.

On occasion the new gravity vent (what most homes have: no blower at the top) water heater needs to be shorter than the old one to ensure that the water heater drafts properly. Another problem that this post prevents is having the wrong water heater when there is little or no extra wiggle room. The best value is a highly insulated water heater. You get savings on your fuel bill for life (of the unit)!

Many people mistakenly assume there is no difference between water heaters except size or price. In my opinion those people have been successfully brain-washed by years of advertising into forgetting that “You Get What You Pay for”. Rheem, in my opinion, makes the highest quality water heaters. The things you can see and the things you can’t (lining on the inside of the tank) result in a long-lasting product. For more information see my other post: Best Water Heater Made

The Gap (“G”) is to help me determine how much room is there for the new unit to move to a different position than the current one? The new units are larger than older ones due to added insulation and thus improved energy efficiency.  Another common occurrence is that a shorter unit is required which is going to be larger in diameter. If the current one is near a wall, furnace or other obstacle, is there still sufficient space for a larger unit?
