Review on 🌊 Efficient Drain Return Slip Barbed Combo: A Practical Solution for Efficient Drainage by Mike Devine

I ordered three sets: 3-3/4" and 3-1". I was missing one of the 3/4" pieces when it arrived. 3/4" works well. A 1" nut just slides straight up the threads for 2 or 3 on the first try and skips over them like they already are been ripped off. I put a large piece of teflon tape on the threads and one worked well enough. to make a gasket. Others would never let me put it on. Tolerances weren't at least 1/16th if not more. Very dissatisfied with this product.
