Wanted to install pvc pipes with nipples hooked directly to a spigot. I used a 11/32 drill bit as suggested, but the nipple will not thread into the hole. The hole appears to be too small. So, my husband used the next size and was able to thread it. We also added a washer and silicone. After drying overnight, we tested it and they all leaked! Any suggestions?
