Review: First DIY Water Heater - Could not afford $3800 to replace my 13 Y/O 50 gallon natural gas water heater so I told both plumbers to pack sand I’ll do it myself using You Tube. Got a new tank for $749, bought the copper fittings, torch and gas and everything else for soldering. Job came out fine, and no leaks. Tinning flux was suggested by a You Tuber.

H-20 95 Water Soluble Tinning Flux - Image 1](https://m.media-amazon.com/images/I/71HDMrNlirL.jpg) ## Questions & Answers **Q: is it supposed to look like a grey colored paste?** A: Yes. The gray color is from a solder powder added to the flux paste. The solder powder is an enhancement to the flux which makes the solder wick into the joint better and faster.
