Davey Aqua select Suction Cover

NO LONGER AVAILABLE Davey Aqua select Spa Bath Suction Cover Use S&P ASF523 white suction cover to replace - the threaded wall fitting will also require replacement (not just the cover). 

For a WHITE replacement -  ASF523 replacement option listed here. 
The thread will likely need to be cut shorter to suit the body fitting behind the bath. 

For a CHROME replacement - you MUST order ASF523 on above link (for the correct body) PLUS ASF480cp listed here (for the chrome cover)

NB. This suction can only be replaced with an ASF523 if the wall fitting can be unscrewed from the elbow/tee in the plumbing. If pipe is evident glued inside this fitting, it cannot be unscrewed and requires complete assembly replacement and replumbing - access to the underside of the bath will be required.
