[ATTACH]67195[/ATTACH] My utility sink and outside faucet are fed by the same pipe, both have the same size pipes. There is a gigantic difference in yield though. My utility sink is running at more than 9.5 gallons per minute, while the outside faucet is dribbling by at barely 2.5 gallons per minute. I've examined the outside faucet and there are no blockages. Taking the faucet apart has no change on the yield. Any thoughts on what the issue may be? If so, is it an easy fix or would it be better left to a licensed plumber? My thought is that the valve is not opening fully. If that sounds right to you, is it a part that can be changed out without removing the entire pipe? Thank you for any assistance you can provide!

MY tub started to gurgle when flushing upstairs toilet, tub sits next to toilet on same line. The tub is used everyday. 1st I dug up septic clean out where pipe meets tank, flushed toilets and everything drained fine. Second, I got on the roof and looked down the vent with flashlight, looked like I could see all the way down. Third, plunged toilet and tub, gurgling went away but now has returned. I plunge the toilet and tub and it goes away but eventually comes back again. Any other advice?
