Edgetec suction Australian approved flow rate of 192lpm. 100mm diameter cover. Sits approx 24mm off wall of spa bath. Common on Lanark spa baths, and others. As of 2024, these are now "stark white." Female threaded wall fitting suits Edgetec suction body only.

Removing the suction face off the body:

• See images for removal of cover - It's tricky!
• There is a raised/embossed hole in the outer ring of the cover that you can easily detect with your finger. Once identified, insert a thin 'tool' such as a pop rivet, allen key, etc through the embossed hole and push down to depress the locking lever. Sometimes if you go one hole back from the raise one, it makes the face removal a little easer.
• At the same time rotate the cover 1/8 turn anti-clockwise.
• Then pull cover away from the fitting.
• Installation is a reversal except there is no need to use the rivet/pin/allen key.
• Ensure the locking lever engages and the cover cannot be unscrewed without aid of a tool.

SLP Replacement: These are now the replacement for older Edgetec SLP suction. To replace SLP suctions:

• Unscrew old SLP face from bath. The entire fitting needs to be removed.
• Clean thread and ensure the rear part with the male thread has not come away from the rear of the bath.
• Use good quality silicone on new thread and inner lip to seal against bath wall. 
• Fill bath and check for any leaks. Ensure fittings are sealed. In some cases you made need access to rear of bath fitting to check for leaks.
