Hi folks. We are set to have gunite this Friday. Plumbers were here today muscling the PVC to get it all back into the form -- some long stretches had slipped under the form and two corners had also been set outside the form. I was worried they wouldn't be encased in the gunite, so had PB call plumbers to fix. While they were here today, they were pushing around the PVC pretty good to get it inside the form. My question is when they set the PVC nearly 2 weeks ago, they tested the water pressure up to 35 PSI. Today, before plumbers got here, it was down to 33 and change. That seemed ok to me for 2 weeks considering evap. Granted, my pump's not running yet, but still. Now, after plumbers were here, gauge is reading close to 32. Is it possible they jostled some unions and created a small leak somewhere? Don't want to call PB for every little thing, but am concerned once gunite is shot, ain't no going back. Am i worried over nothing? A pound of pressure over a few hours?
