Overflow Drain

[bpf45]

Hi, this is my first post. We bought a house with a pool about a year and a half ago. We kept the company that serviced the pool for the previous owners. I am thinking about moving away form the service and maintaining the pool myself...that is how I ended up here.

We are having an issue with a Leyland tree that looks to be dying in our yard. It is directly behind the pool and I think it could be related to the overflow drain, which appears to either dump the water at it's base or the pipe may run below it and could have been damaged. We recently did a backyard project. OUr landscaping company thinks that the pool salt water could be killing it.

Yesterday I took a hose and ran water through the drain but could not find where the water came out. So a few questions as I don't know how the overflow works really.

Is the drain attached to the main plumbing system for the other pool components? Or is it just a simple pipe that runs and dumps the water some where below the level of the pool drain?

Should I be able to see where the pipe terminates or could it just be somewhere in the ground?

There is a valve under a green over that you can see in the picture attached. That is in perfect alignment to the overflow drain in pool. It is also next to the auto fill float valve. Which one is it tied to?

The pool was built in 2017 and the Leylands are very tall, as you can see in the pictures. The Lelyand turning brown started happening after we moved in.

Any help or guidance on what I can do would be much appreciated.

Thanks

45,

No one here could know for sure..

Many overflows are tied into deck drains and then out to the street.. Many are just piped a few feet and into a dry well... Others just have a pipe going down hill and then to open air.

I really doubt that the valve in your pic has anything to do with your overflow port.

A lot of autofill systems have an internal overflow port..

Thanks,
