    Inter 18x48 new 3 hole style liner

    Replaced intex 18x48 liner. The new style has 3 holes. 1 for supply. 2 for suction side. Had old 2 hole hard pipped. Any ideas how to hard pipe the 3 holes? Extra supply inlet? Already use Hayward skimmer and use other hole as extra suction outlet. Extra hole to contend with.

    If you've got a skimmer and an extra suction hole, it sounds like a second return is called for.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Cut out the two skinny holes put in 11/2 inch fittings. Now you have extra returns. I vacuum with one and run my water fountain with the other.

    Kinda what I was thinking. Skimmer + 1 extra suction outlet and 2 returns. I bought 2 Hayward eyeball inlets. The locations of 3 holes now is a little awkward. Calls for new piping scheme. More valves, joints, unions and pipe now. But should be fine after the modes.
