Still on the Journey to get my Jacuzzi Brand tub rehabbed here is my latest need for advice. My tub has an american products spa-brite light with a wet niche. I am going to be running the gray PVC conduit to the niche, probably the flexible type. The niche has a hole about 1" in the back of it for the cord. I read somehwere something about using a waterproof PCV connector to connect the conduit to the niche, what on earth is this? Is this a connector that no water can go back up into the conduit or is this one of the connectors that has the oring to keep water from leaking around it? If I am wrong on both ideas anyone have any others? All of the equipment is external to the tub and this is my idea for hooking up the light. I will runing rigid PCV conduit to the underside of the cabinet and put a junction box of some sort then use the flex PCV to connect from the box to the niche. Once the cord is run in the flex to the box I will probably seal the end of the flex in the box with silicone.

You absolutely MUST contact a local electrician or pool builder before going forward with this. This is NOT a situation to be taken lightly.

First off, I'd consider investing in a 12 volt light fixture with transformer, and stay away from a 115 volt fixture. (You can find them all over the internet cheap).

Next contact a PRO LOCALLY that knows how to do this and at least talk to them on the telephone so you can get an exact sense of what to do with what you've got. Local codes often differ and I know you may not care (as most don't when they're doing stuff on their own), but looking for advice like this online is extremely hazardous since once you've buried it, you've got to live with it or DIG IT UP AGAIN and FIX IT.

This is one of those things that you will either:
1. End up Hating yourself for forever... or
2. Love yourself and enjoy pbr's by the tub for years for making the right choices to begin with.

A bit of simple stuff here....

A. An inground style of lighting fixture like this, has conduit that is FILLED WITH WATER 24/7.

B. The light fixture is factory sealed. To replace it you must replace the fixture AND cord at the same time. So if you've got a 50 foot run to the electrical box, you've got 50 feet of conduit filled with water.

C. High voltage light fixtures like this are a primary killer of pool service personnel.

D. You don't seal anything with silicone on this line, other than to help seal the junction at the conduit to the niche to prevent water leaking from the tub out of the conduit hole. Water will always be in the conduit all the way to where it exits UP above the top of the spa/pool waterline.

Honestly, I don't mean to raise a bunch of bs alarm bells here but this kind of fixture will be the one thing you absolutely hate, and if it's not 100% correct will cause you misery forever. So do it right and contact a local pro to get their advice on the exact fittings and parts they use to do the job. A pool contractor will give you no info other than they guy they use for their electrical work.... And that's the guy you want to talk to.

heh heh... it's 'that guy'...

The cord was another question I had. The previous owner cut the original cord to a length of about 10ft and I need about 30ft total of cord. I was assuming that at the least I would need to replace the cord itself but I was leary about. Since I don't fancy spending more than I already have in spa for a new light I am thinking of sealing the hole in the back of the niche and just putting the light back in without hooking it up so there is not a big ugly hole in the side. I am then thinking about installing some of the small led fixtures like the ones below. But then my next question, how many lights can you run from one transformer?

That's the best idea. Reinstall it, plug it up...

Then cut a separate light hole with a jigsaw.

I don't know what the actual current draw of one of the LED fixtures is. But with that transformer assembly you're limited to 1 amp... 12 watts max. Well, with one of the newer led fixtures, you really only need one anyway, with two you'd end up with some garish color combos and stuff and you probably wouldn't like it very much.
