Hi, I have older spa that came with the house when i bought it. There are some issues with it that i decided to fix but got into a problem with jets. I simply cant figure out what are they & what replacement parts I should order for them. One picture looks very similar to this: Waterway 212-1267 http://www.poolandspapartssuperstore.com/waterway-plastics-adjustable-mini-jet-internal-scalloped-pulsator-gray-212-1267-806105029669/ But it is still a bit different. Can you please help? Link to a folder with pictures: https://drive.google.com/folderview?id=0B0pUD7N0nY5ORDNhQndfRGpvSk0&usp=sharing
