Think of pools and think of fun, sun and summer. You usually don't think of cleaning, and pool drains right off the bat. In fact, some have never even heard of a pool drain until they are installing their own pool.
A pool drain essentially serves to filter out excess dirt and debris. It can really help keep your pool clean, and reduce time (and money!) spent on maintenance.
Some companies however do not use pool drains, finding them hard to winterize, and in Upstate, NY we know winter.
It really comes down to your preference, and what your company thinks is best.
