I had a pool company close my pool last year, and yesterday I realized that the 2 plastic plugs for the heater (older Raypak 2100, dark green metal exterior, probably 15-20 years old) were still in place. I am not sure if they undid the plugs for an hour or 2 while they were here, and put them back in...or if they were left in all winter (I live in Michigan). All the other plugs for the pump, filter, were taken out and left in the pump basket all winter. All my pool equipment is inside a brick pool house.
Is my heater toast? Will I have to order a new heat exchanger, maybe other parts, due to freeze damage? Or will I be ok because the water likely drained out through the filter/pump during the 2-3 months before we had any freezing temperatures? If I understand, the heat exchanger is where all the water is located inside the heater, which is up high...couple feet off the ground...so the water should have drained back down through the pump drain...?
Also, is there a way I can/should test my heater for damage/leaks before I open my pool? I have a month, so if I could figure out if it was damaged and repair it before I open my pool this would take care of the problem so there were no surprises come Memorial Day. Thanks!
