Water Heater Questions
"Ken Hall" wrote in message Question 1: I read you should replace the cheesy plastic drain cock with a ball valve so you can get full flow when draining the heater. But, there's some kind of safety cover over the drain cock that prevents putting ball valves (which are larger) on them. So, if you can't do it, why is it recommended? Because it is a good idea if done properly. Sounds like they don't want you to in this case. Question 2: This is a self-cleaning unit. Do you drain self cleaning units? Is so, doesn't that mean they're not self cleaning? This is probably the reason they don't want you to change the valves. I have no idea how well this works. Question 3: Sure enough when he cracked open one of the connections a lot more water drained out. Why does a connection at the heater have to be opened to get it to drain completely? Vacuum. Put a straw in a glass of water. Put your finger over the end and lift it out. Same thing with the heater. If air is not allowed in, the water cannot get out. |
