Yes I know what your saying, and Im as lost as you are about how they build them, but if its lined, then the welding process would have heated up the tank enough to melt anything inside of it.
yours may also have a bladder like mine as well, but instead of having a "trap door", they recessed the bladder seal somehow, so you wouldnt see it.
then they could have collapsed the bladder down and welded it.
Im actually going to see if i can contact the manufacturer of the tank, and ask them how they assemble their units.
As for your pump, I have seen the documents, and have had much corrispondance with Aquatec, as I will be purchasing a 120 PSI model at some point, and the transformer or power source is prety much my biggest issue.
the 120 PSI pump draws more than the 2A their transformers provide.
that aside, all of the documents list the pump voltages as 12 or 24VAC, but when I asked the rep about it, he said they were 12 or 24VDC....so I'm not really sure who to believe, I was actually hoping I could find someone who has an 8800 series pump and could tell me what their voltage is
I'm not 100% sure about using a resistor to step down the AC voltage, But I'm pretty sure it can be done, thus providing plenty of amperage for the pump to run.
I have, for some reason, been unable to find any good solid info on using a resistor to step down the voltage.
