Thanks everyone for the advice. I bought a brass check valve for replacement. I was warned this might not be an easy job, as the EZ out to extract plastic threads may not work. Naturally that proved more then accurate. I ended up sawing grooves with a jig saw blade. Then using a screwdriver and hammer to pry out pieces. Most of the plastic was stuck like it was welded. I used a soldering gun with a flat heating element to melt and leverage out plastic. I then bought a 1/2" nppt thread tapper to clean and push the plastic out. I followed that with a dremal size wire cup brush to finish cleaning the tank threads. Then inserted a brass check valve. NEVER PLASTIC AGAIN! What a job...

I've heard a lot of discussion concerning plumbing tape. The consensus is that its not that effective and using a quality plumbers pipe thread sealant goop, is better as a stand alone. I used Rector seal T plus 2 with PTFE. Available at most hardware stores. I applied a good coating to the brass check valve and no leakage was found. I think I may be done with tape.

I'm too late to this party but Orbit makes this tool for removing 1/2" and 3/4" nipples that break off inside a fitting. I use this often when making sprinkler system repairs. Home Depot and Lowes carry it, or $5.00 on Amazon.

I'm also late to this party, but dissimilar (galvanic) corrosion is a real concern. If the tank is steel, a brass fitting will not be much of a problem, but I have heard that newer water heaters are becoming aluminum.
Brass and aluminum REALLY don't like each other and your first indication of a problem is you will never get the fitting apart.
To be safe, I would use a stainless fitting between brass and aluminum. It is not ideal, but the alternative is much worse.

I really wonder if this will work on the water heater tank as the check valve has some type of pipe sealant on it's threads, and this seems to cause the problem of it being difficult to remove and then breaking. The pipe nipples that break off in sprinkler system fittings are usually pretty loose and have no sealant.
As mentioned earlier in the thread even an EZOut tool seems to just ream out the stuck plastic pipe nipple.2020 Reflection 273MK

What would be ideal then? I'm wondering. After reading up on this, I feel like I had better pull the brass check valve out and do something different. Ideally, a 1/2" mpt x fpt pcv riser between the brass and aluminum. Maybe just tape and pipe dope on the brass threads.
