glug-glug noise after toilet flush
Posted by mary on July 23, 19100 at 14:19:55:
I had new Gerber Ultraflush installed about 6 weeks ago. REALLY love it but have noticed an odd glug-glug noise about 30 seconds after toilet stops running. Sounds similar to the old "water cooler glug" sound. It glugs once and then about 30 seconds later glugs again. No noticeable leaks or problems, but was wondering what this might be. Any ideas?
