Well I am so frustrated and embarrassed. But as I have heard on the board before, experience is what you get just after you need it. I am adding two returns to my steps on my vinyl liner pool. They are Hayward 1408 inlet/outlet fittings. I drilled 3 inch holes just like I did on my wall for a vacuum outlet. Well, it looks like for this I need to install a Hayward 1411 which needs a 1 7/8 hole.
Please tell me I can fix this. Is there a different fitting I can put on the steps?
Thank you so much.
