"Purchased the deal in the evening on Friday Feb 12, 2016. At time of purchase I advised vendor that best way to reach me is by email or Angie's messaging. Also provided two possible dates in March for the work. Winston responded the next day via Angie's message, and we set up the service date for my  next weekday off, March 2. And I sent him some pictures of the plumbing and street valve. Could not get a commitment on an arrival time, but he called me that morning and advised he had a 9am dentist appointment, and would arrive after that. Showed up with his helper about 1.5 hours later. We could not get the street valve cover off, and thought it belonged to the city, so I made arrangements for Winston to come back today, March 15.
I called the city water dept, and they sent someone over, he said it was not their valve, it was mine and he couldn't touch it, I guess each city is different?.
Anyway, I got the cover off with the help of a saw, a big hammer and a pipe wrench in time for Winston to come back today. We communicated via Angie's messaging in the meantime. Still could not get commitment to arrival time, although I asked for 8am.
Called Winston at 8:15 this morning and he said he would be her by 9:15, arrived at  9:00. We could not get the street valve closed, it was stuck. Not surprised, as it has not been accessed in at least 30 years!. We decided he would put the new valve just downstream of my existing shutoff, and from now on, will not use the old one to prevent further leaks thru the valve stem packing. I also asked him to rebuild the hose bib in the garage adjacent to the main valve, and install heat tape on the pipe before wrapping it (I already had the heat tape, just never got around to installing it. When attempting to replace the washer in the hose bib, the retaining screw broke, so he installed a new hose bib into the old valve body for me. Although I was willing, Winston did not charge extra for the extra trip and the extras I asked him to do.
Overall, I am more than satisfied with this experience. My only complaint is not getting an advance commitment on arrival times. But once I did get a time, he was punctual, even early. Would give an A- on responsiveness if I could. But overall, an A experience!
Will definitely use A REAL PLUMBER again. In fact, we already discussed installing a freeze-proof valve for my backyard hose bib.

"Service guy came as scheduled. Sent his "service" requirements to home base Home base calls back and lists, a very long list of what needs to be done and a very long list of what is not covered and what each item costs. The overall cost was outrageous and they weren't willing to give it to me in writing. Everything I had to pay for was overpriced, of course! They told me my other option would be to purchase my own water heater and they would reimburse me for what there water heater would cost, but no reimbursement for Labor, building permit, or any upgrades required by the local building department. The requirements of the building department were minimal. I went to Home Depot and had them do the installation and saved many hundreds of dollars. Lesson learned, have AHS do simpler repairs that don't require municipal building department approval. Have AHS pay for the equipment, and purchase installation from a trusted local installer."

Water Heaters FAQs, answered by experts

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters—both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.
