Air in my hot water line
After initial installation I kept getting air in the line. The company said "It's the anode rod, we've redesigned it." So they sent the new rod, and I paid the money to have it installed, and had the exact same problem. I kept asking everybody I could talk to if they had run into this before... nobody had. I asked everyone if it was possible that the high wattage elements could possibly be electrolyzing the water into hydrogen/oxygen, everyone laughed. Finally after another year or so, I happened to have a piece of 1/4 inch Lauan down in the basement, and with much difficulty I managed to "slip" it under the hot water heater, separating and electrically insulating the heater from the concrete floor. Voila! No more air in the line. My conclusion? Electricity is leaking somewhere to ground causing current to pass through the water and electrolyzing the water. But no more.  |

| now that really fills me with confidence that the plumbers know what they are doing.
I guess if you have rapid recovery, you could go with a smaller tank. The source or tankless heaters have been in Europe for decades, but the only one I know of here clogs up every few years and it takes $500 worth of parts to replace the clogs. I sure hope they are saving $$ in heating to justify replacing the guts every few years. |
| I should have held a match right near the faucet (under the faucet probably wouldn't have worked! ) But I was always afraid to try... |
| being the new ground could have made for a bad day. chances are the O2 amount for the match wouldn't have enough for an quick air economy flight or early July 4th. You could have spread soapy water over the area, but that goes back to the first line.
Glad it all worked out safely. |
| It's not the O2 that I was concerned with, it was the H that worried me... they'd be fairly well mixed and ready to return to a liquid state with the provocation of a match. |
| Was that a dangerous situation?
Good thing you're smart and solved the problem. I know there was a dip tube problem with some hot water heaters where the plastic part was breaking apart and ruining plumbing in some instances. We had pieces of the dip tube breaking off and causing the faucets in the bathtubs to not work properly. So it had to be taken completely apart to get the plastic pieces of dip tube out. We finally replaced the hotwater heater. We have a 50 gallon and with three bathrooms they consider that about the right size. But 40 gallon would have been OK they told us. I just wanted bigger because we get a lot of company. |
