We Have A Glacier Bay Bathroom Faucet That's Been Dripping. A Series 300 That Uses The Small 7/16 Rubber Boot And Spring That Fits In Approp. Hole In Water Supply Then Over The Top Fits A Turnable Water Control. Well, I Have Replaced This Type Before W/o A Problem But This One Leaks After New Ones Are Installed With A Replacement Type... not From The Mfg.
Is There Something That I Have To Do With This Model Unit To Seat It Properly??
