The correct set up procedure has not been followed. The cup needs to be fitted so that it finishes flush with the wall lining. [–]

When installing an acrylic lining, there is a different fitting procedure used. Please see correct fitting procedure in the instructions or on the website. [–]

Supplied in the packs are tubes of sealant, this sealant is to be used around the outside of all penetrations created in the flange of the Wetwall Caddy. This is what bridges the gap between the wall lining and acrylic lining, and between the waterproof membrane and tile. [–]

All tap manufacturers require a service hole to be removed from a wall lining to allow for easy access to the fittings of a shower mixer. Typically this can be between 50 mm and 100 mm, depending on the size of the face plate. This requirement is applied to the flange of the Wetwall Caddy, the wall lining, and the tile or acrylic lining. Water will then fill up to the lowest point on the flange, and via the egress hole in the faceplate disburse down the front of the wall. [–]

When installed correctly the flange of the Wetwall Caddy will have a service hole removed from the face to allow for easy access for servicing. Water can only fill to this level before it overflows out the front of the device and down the wall lining. [–]

In most cases shower mixers will have a small hole situated in the bottom of the face plate to allow for the passage of water that builds up behind faceplates. Alternatively the correct procedure for fitting a faceplate requires a horseshoe shaped bead of sealant to be placed around the area where the face plate is seated. This creates an egress opening at the bottom of the faceplate. [–]

The outside rim of the flange is 1.5 mm thick. The inside portion of the flange is 3.0 mm thick. [–]
