I replaced my water heater earlier this year....Here is what I found new to me.
In 2004 I replaced my homes water heater with a high end, professional grade unit, that was about as top of the line as one could get that year in terms of a plain, gas fired, water heater.
I did not need any special monitoring, electronic controls, or other devices that year so i purchased a good water heater.....and it lasted 20 years without an issue.
Yeah, I did regular flushing and other maintenance items as suggested by the manufacturer, but for the most part the water heater just heated water for 20 years straight....Good in my book.
This year that old water heater tank began to seep water....just a hint of moisture on the floor and after checking I found a slight crack in the main tank.....time for a new water heater I figured.
Guess what? The new rules, at least here in Minnesota, will not allow me to purchase that level of quality water heater without a professional plumbers license.
I tried, and tried, and eventually ws relegated to buying what the home stores have to offer.
Menards, Home Depot, LOWES do NOT carry the quality level of water heater I was replacing, but seeing as I don't have a professional plumbers license I could not go to other suppliers to purchase a high end water heater.
I purchased a nice water heater from LOWES, and it was on sale too.
$1,200 for the same basic parameters water heater I purchased in 2004 for $365, but the new version is nowhere near the quality.....I hope it lasts ten years.
I learned I have been restricted by new commerce laws concerning what I can purchase and install in my own home....for my own safety of course......
I learned I, effectively, can not purchase a high quality, well made, water heater because the stores simply do not carry those items any longer...The homes stores do not have the brand name or models I had before eventhough that brand name and model is still in existence and not rare in terms of what plumbers can attain.
I learned it now costs me 4x the price to get lesser products than just 20 years ago.
I learned the industry has become complacent with the idea that 10 years is considered a long time for a water heater to last.
I learned that expansion tanks are made to last 3-4 years.....just 3-4 years before they are expected to fail!!!!! and the industry is fine with replacement ever 2-3 years as the normal.
Yes, there are some critical things one must know and understand when installing a water heater....especially during initial install.
But the level of expertise required to replace and existing water heater is basic common sense and attention to details.
The water heater I replaced in 2004 was 12 year old unit with the cobbled result of a "professional" (all the tags, receipts, and paperwork were present from the company that did the work) install that required me to fix the gas piping system, exhaust venting system, water plumbing system as well as a few other items when I did my install of the new water heater in 2004.
All the work I redid, as a non-professional plumber, was far superior to anything I have seen in other homes, and was a HUGE improvement to both safety and usability in my own home.
This work/repair I performed in 2004 resulted in me having to do very little new work in 2024 with the recent water heater replacement, and the new unit is a different make and model than what was removed so i expected there to be some modification required......nope, pretty standard dimensions, making the removal and install pretty easy by my standards.
Now, with that in mind, I was quoted in the $2,000+ range to have a professional install the new water heater I just put in.....and the price of the water heater would be extra on top of that.
I was not aware plumbers were earning $300-$500 per hour these days.
As it was, I invested a total of about 20 hours between initial diagnosis of the failed water heater, research and subsequent failures to attain a new water heater due to the BS safety rules preventing me from purchasing what I had previously purchased, removal of the old unit, clean up of the surrounding area (a thing you will NOT get when the PRO does the install) and install of the new unit.....which included diagnosing and replacement of the gas valve under warranty because the brand new POS gas valve did not work right out of the box.
Had I paid to have a plumber do all of the work I did I would have likely had $4,000 into this water heater replacement.
Instead I purchased what I could and had it installed on one weeked afternoon.
Had the gas valve not been faulty I would have gone from shut off and removal of old to fire up and use of new on that Saturday.
My mechanical and electrical knowledge and abilities have been useful my whole life as I undertake these tasks that, to me anyway, make sense and seem relatively simple.
But with this new twist of "NO you can't for your own safety" becoming a real hurtle to my own self preservation and maintenance of my home, I have become a bit concerned how the future will play out in my ability to afford the things I have come to provide for me and my family.
$3,000-$5,000, expected every ten years for a water heater, furnace, A/C unit, along with all the other expenses normal life brings...and I'm not even talking about an extravagant lifestyle, seems untenable from my positon....and I am doing a bit better than average!!!!!!
