Do not re-surface the pool without removing the nozzles as this will damage the nozzles. The nozzles in the pool are specific to the body they are in, so they must be marked as to which body they go back into. There are covers for the bodies once the nozzles are out to protect the bodies and pipe from material getting in them during the refinishing process.
