    Polaris pressure leak under deck

    I'd welcome some advice on my situation on my 20x40' in-ground vinyl pool.

    We have a ~20-year old Polaris 280 that keeps the pool clean. We've detected a major water leak in the underground pressure line. I had the same line repaired twice about 4 years ago for about $2000. The repair involved lots of manual digging and identified tree roots as the cause. Subsequent tree removal was another $2000.

    Ignoring cost, the right thing to do seems to be to replace the entire run of line from booster to inlet. That line runs under at least 8 feet of concrete. (prior repair replaced partial line until the edge of concrete). I imagine that's another $2k, and afterwards, the new concrete won't match the old.

    Sooo... Do I just plug that line and use a different type of cleaner, like an electrically powered unit? Or do I run an "over-the-deck" kit for the Polaris? I find the over-deck kits for sale online, but no explanation for what they are or how they are installed.

    I would appreciate any input or advice.

    My personal opinion would be to abandon the existing line and either go with a different type cleaner or go with the above deck line. I'd lean towards a different type cleaner.

    Buy a robot and cap the pressure line.

    I agree with Rescue30. It is going to cost you more to fix the existing line than it will to buy a top of the line cleaner.

    Plug the line and buy a top line robotic cleaner. You will not miss the Polaris. And you will still be ahead vs the cost of repairing the line.

    OK, thanks everyone! It's unanimous. Enough with the Polaris repairs. Time to shop for a new type of robot. I will look back through this forum for product recommendations.

    Thanks a lot for all the input.
