Since we purchased our house a few years ago, the spa jets have never had good pressure. On feels like a strong garden hose and the others are worse.
I just had a repair person out who confirmed that the filter was clean so that wasn't it.
I was told that the only other cause could be blockage in the line, and to have it blown. He said that normally that from the Venturi (line? I forget the word he used - described it as having holes in the top to take in air) you could hear air flowing in/through but he couldn't hear anything.
1. Does this all make sense?
2. Any other possible causes come to mind?
3. If blowing the lines is the next step, what does that involve?
I really appreciate the help. TFP has been an incredible resource.
