I have a Jacuzzi J-345 and the plastic adapter that comes out of the two-stage pump and the hose attaches to is broken and leaking where it threads into the pump housing. I was able to find a new adapter, and I have a tool to get the old one out. But before I replace it I have a couple of questions...1) do I need to completely drain the hot tub in order to change out this adapter? 2) when I thread the new one back in, do I need to use teflon tape or any kind of sealant?
Thanks.
