Installation
The proper size of the drain must be selected prior to installation. Once the proper size has been selected, the seal is inserted into the drain pipe's stem and the castle head system should be tightened to expand the top half of the seal, locking it to the drain stem. The entire assembly must then be placed in the roof drain pipe. The castle head must be further tightened until properly fixed in place. The drain is now leakage proof.
In case the leader pipe of the roof drain cannot accommodate the length of the drain pipe stem, cut the drain pipe stem to the required length ensuring approximately 2 in. is left attached, to allow the top portion of the seal to be inserted in. The overall minimum height required of the roof drain opening is approximately 4 in.
