Hey all,

I am a newly indoctrinated pool owner, having recently bought a house with a pool. According to the previous owners, the pool and system are about 10 years old. The previous owners also took care of nothing properly, including the pool. So, I have spent quite a bit of time over the last 3 weeks trying to get the pool up and running.

Anyway, my specific question to get started: my sand filter (Hayward S200) is making gurgling noises and water is slowly leaking from the top of the cap. See photo here: http://flic.kr/p/9UAQ8s
Is the leak most likely caused by a failed O-ring? Can I easily replace this? Is that where I should start?

As for the gurgling noise, any clue what this means? I fear I have bigger problems, but I'll wait to until this first round of question gets answered.

Thanks for any/all help. Glad to be a part of this great forum.
