Water Heater Leak

[PrevostNewbie]

Yesterday, I had to vacuum the sediment out of both water heater tanks, flush with fresh water for about 15 mins, then vacuum. I did this 4 times for each heater and I think they are pretty clean for 28 years old. The new elements are installed, powered up, and started to heat the water. I only gave them about 15 minutes checking voltages on the heaters, thermostat and cutout, the water didn't have enough time to get hot but it was warmer. I will leave the system pressurized and heaters off overnight to see if there are any leaks before I button it up. I will be glad to put the water system behind me so I can move to the Webasto.

Mike, a 30 year old hot water tank that's not leaking or about to leak is pretty impressive.

Thanks! maybe it was the silt insulation it had on the inside. It has been sitting at 40 psi for almost 24 hours now and no pressure drop yet.
