Leaky Tub

I previously showed our Crowded House (Spa) photo, well it will be Six months in a Leaky Tub if we don't fix the leak. We have cleared out some space and opened up the panels to give some access to the workings where we have fortunately located the leak. However the mechanism that is dripping seems quite tight.  The water is pooling all through the support woodwork and cabling.  We have bought a $7 seal,  and replaced the old one which appeared to be creased and letting out water. We saved a $150 service fee.

The leak is on the left side below the handle
