I have a leak in my hot tub where the nut cracked in half connecting the pipes to the pump. I found this link earlier that might fix the problem http://spapartsnet.com/p_Spa.Parts_PLWS ... 8_1_1.html. I had previously posted on the site and someone identified my hottub and for some reason that post is no longer here.

Hopefully someone can give me an idea of what brand my hottub is:

It is made of black plastic and is totally round. I believe they sold them at recreational factory warehouse at some point (I can't find anything like it on their site). The "arm rests" are made of black foam (maybe) and are removable.

Any ideas what brand that may be? It looks similar to the following but it is a black smooth shell.

That is a "Dream Maker" Eclipse spa.
Dream Maker is a subsidiary of Leisure Bay Industries, or LBI.
Parts and info should be available through them.

Your spa is it's earlier version called a "Sport Spa"
The spin molding facility went out of business several years ago.
The parts are similar. Yours has a "Tri Delta" control system, and
an lBI pump.
