I am a new unground pool owner and feel pretty comfortable winterizing my pool reading the multiple articles here on this forum and watching some videos. However, i have a few areas of concern that I have been unlucky finding information on and can use the communities help. I will post pictures following the questions.
First, I have a main drain that the pool builder installed with a few check valves and what appears to be a service side that has a plug. The check valve on the service side allows flow down and the other check valve allows flow up. My assumption is if i close the valve going to the pump, i should be able to remove the plug and blow out the main drain and the check valve on the service side should airlock it until i secure the plug. Am I on the right track with that assumption or is that designed to put RV antifreeze?
Second, I have a spa step with 5 jets and another port at the very top that I have no idea what it is for. For closing I was going to blow air through the jets and close one jet at a time and then open the top port and close it if no water is coming out. Is closing the jets sufficient or should i be putting another device or plug on jet? Does anyone know what the screw on plug at the top of the spa steps is for? Thanks in advance for any help you can provide.
