Got my very first pool up and running a short 21 hours ago. Had the pump running since I filled it with water, no problems. However, I just checked it again (3 hours shy of running for 24 straight hours) and there is a light but steady flow of water coming from the backwash drain. Enough to make a little puddle below it. Normally, the PSI was running at 10-11 thoughout the day, but it is down to 8 when I noticed the light flow of water coming from it. Being a new pool owner, I'm not sure why this would be happening, so any ideas would be appreciated. Thanks.
