Trying to figure out my plumbing.

I'm investigating more and more into my new to me pool as I find time. I'm considering an automatic chlorinator. I'm thinking with my busy schedule it'll help me from getting behind. To figure out where to place it my reading has determined I need to understand the plumbing better. The heater doesn't work but I believe it's flowing through it still. The easiest place to put it would be before the heater but everything I read says it needs to be after it. There's another little line running that I'm not sure what it is.

I drew the arrows for how I'm assuming it runs.

Looks like you have everything labeled correctly. And it looks like the water IS still flowing through the heater. If you don't plan on replacing or repairing the heater I'd suggest removing it.

Also, the canister thing you point to behind the heater looks like a chlorinator of some sort. It looks like an old Hayward model, but I can't see it well enough to tell.

What type of chlorinator are you thinking about installing?
 
The TFP method (and it's proponents) will advise against an auto cholorinator since these pucks will raise your CYA to unacceptable/unmanageable levels eventually. However, if used for short periods (like extended vacation), then it's more 'permissible'. We too have a "new to us" pool that the previous owner used Trichlor pucks and the CYA is in the 80-90 range, and really unacceptable.

The pucks I bought are just chlorine, I saw all the added stuff on the other option and steered away. My cya was at zero when I first check, have it about 30 now. Still trying to find tune it.

No pucks are just chlorine. You need something to bind the chlorine to make it a solid. Chlorine naturally is a gas. Either stabilzer/CYA or calcium is used. Using pucks gets increasing amounts of one or the other.

Great, now I have something new to research. Any recommendations? My current pump is a pentair but is only a single sweet that looks pretty old. It'll probably be upgraded in the coming months/year.

It would help us help you if you put a description of your pool and pool equipment in your signature. See Read this before you post.

Eventually I'd like to repair(if practical but it looks pretty old) or replace the heater. No real time frame on that or what it'd be replaced with though.

Clorinator wise I was looking at the pentair 320 just to stay with brand but nothing set in stone. Now a SWG is looking real appealing. It looks like the 1" line might be plumb to it and looks like it might be tied into the return line under ground.

Thank you for the input.

If that's the case then I'd plumb in a bypass for the heater and leave it where it is. Just make sure you drain it when you bypass it.

If you'll read around here a little you'll see that we don't recommend any type of tablet feeder. If you want something "automatic" we suggest either a SWCG or an injection pump.

As for the small line, I kinda figured it may have been plumbed into the feeder and then to the pool.

Do you have a spa?

I've been doing a whole bunch of reading, enough that my wife stays mad that I'm on my phone all the time. I see circupool recommended a bunch vs the big names. SWG seems the way to go, now to just decide which one.

I think there might have been an above ground spa at some point, there's a circle of the pool concrete decking poured offset from the pool. Can't think of anything else they might have used it for.
