Hi, My main drain cover broke and I am needing to replace it. However, was told that due to the fact that the cover is discontinued, we will have to drain the pool and then change out the main drain "neck" for a new one with a cover. Something about this just seems unnecessary (I might be wrong as I'm clearly not a pool expert) and just seems like there could be a universal style drain cover that could fit my dimensions. I'm including a picture of the drain cover and the drain at the bottom of the pool for reference. The pool is about 15' by 30' and ranges from 3ft to 6ft. Thanks in advance for your help!
