The Isopiestic Seal
Isopiestic Seal
An Isopiestic Seal provides dual action sealing pressure for both the internal and bottom seal by equalizing seal pressure initially and over time as the seals set. This is a secondary sealing action providing a water tight solution.
Isopiestic Seal Opened
Isopiestic Sealing dampens vibration and fill valve movements from water pressure shocks or toilet rocking. Locking Detents prevent fill valve nut loosening and backing off due to fill valve movement. Engage Locking Detents by firmly hand tightening the fill valve nut.
Isopiestic Seal Tightened
Isopiestic Seal is easy to install. To secure and lock the seal in place just firmly hand tighten the nut to engage locking detents of the Isopiestic Seal against the bottom of the toilet tank, as shown below.
