We are shopping for estimates on having our pool resurfaced. Some of the pool contractors have stated that the main drain needs to be in compliance with VGB. But, these estimates include this as an optional item. Is the MD required to be in compliance with VGB and have a split MD?
I swam yesterday and dove down to the MD and it was not pulling in any water when my pump was on. So that got me thinking is it supposed to pull in water? Could there be something wrong? If not, and it is not intended to be an intake for our pool, then I could save the $ by not having the MD split.
My intake is in the skimmer. There are two holes. One pulls in water and the other doesn't (not sure what it is supposed to do).
Any input would be great. Thanks.
