Can I buy just part of your setup? Anonymous asked on

No, our design is made specifically for the pump, filter, and chiller that we use so we only sell the unit all together.

How do I drain the unit? Anonymous asked on

You can drain from the water hose connection at the tee coming off the drainage hole, or you can connect the included water hose adapter to the return jet, attach a water hose to it, and pump the water out. Please see video:
