PB installed Hayward Deck Jet Model WFJ500. One of the jets won't drain and water collects on top of the housing. I am thinking this will be a freeze issue, plus the water that collects there smells really bad. I have added an image from the install doc that shows what mostly likely was done wrong. I can't tell from the drawings from the doc, but do the drain holes just go straight down and are open through the bottom of the housing. Anyone have one of these isn't installed yet and can tell? I am thinking I could take a thin long masonry bit and drill straight down each drain hole. There are three drain holes and all are blocked. Obviously don't want to cause a leak and make an even bigger issue. TIA
