Good Afternoon All,
I'm somewhat new on here between my wife and I. I've taken over pool duties and have finally decided to tackle my leaking and older solar heating system. I don't know a lot but have managed to fix some of the leaks in the system. The system is a heliocol and I think the pool was built in the mid to late 80's. I bought the house with the pool, hand have had pretty decent luck maintaining and cleaning, with many trips to the local pool store and visits to this website.
Back to the solar.......
I turned it on yesterday, and by turn it on i adjust the valves to divert water to the system. There are some leaks, about 6 or seven, and most of them are coming from connections of the main pipes. I've taken a couple apart, inspected o-rings, lubed up and reinstalled (which is what i was told to do from the heliocol dealer), i've had success on one, one is still leaking. I've read on here that you need to drain your solar system. I'm not sure how to do that. I'm sure I'll have plenty of other questions regarding this as i dig deeper into it. I will include pictures of the plumbing near the pump and filter.
Any help would be appreciated.
