Light Repairs
I have epoxied a bunch of lights this year using Pool Putty 2 part epoxy. (white & blue) For the most part it works great. But I have had a
couple that I have had to go back because the light was still leaking. I try to be careful but the cord gets pulled to the side when I put the light
back in and leaves a small crack in the epoxy. I have left the lights out and let the epoxy set when I have a problem but this is time consuming for
jobs that are far away. Any suggestions or advice?
Thanks,
Mike

Light leak
I used to use two part epoxy also but have since found the the butyl rubber is the best. I know of guys using hi expansion insulation foam and it
works but good luck getting the light out to change the liner or for other repairs!!

I use Aquabond underwater epoxy to repair the lights. I have the customer reinstall the light due to cure time. If they dont know how, I show them
before the repairs are made so the cord is not disturbed. I have never had a recall because the repair failed.

While epoxy repairs work fine on light conduit leaks, they may present a problem later if the light has to be removed and/or replaced.

Light conduit leaks-
90% of the time I seal them with the butyl rubber sealant from Anderson, works at all temperatures, is removable at liner change time or to install a
new light, and you can immediately put the light back in, 10% of the time I use epoxy, if the conduit has sheared off at the back of the niche for
example, if i use epoxy I always use Anderson's Fast Set epoxy ( in the red package) sets fully in 5 minutes and allows you to reset the light in the
niche

Every time and I do mean every time I've used butyl tape on a leaky light conduit it falls off. I must be doing it wrong. I've used blobs about the
size of a marble to a golf ball and nothing seems to stick except A&B epoxy. Can anybody help me with a good technique?

It is how you pack it into the conduit.
1 clean the first 2 inches into the conduit with a toothbrush
2 feed in the butyl rubber going around the cord and usually the ground wire and pack it into the conduit, forcing it in with the blade of a
screwdriver. when you are done it should be at least one solid inch packed into the conduit. It is flush with the niche when finished.

Thanks Bruce,
That's great advice. I doubt a toothbrush will fit in the 1/2" brass conduit we use in AZ. But I will find a proper tool that will fit for cleaning
the space between. I've never seen a ground or bond wire in a light nitch on the water side of the nitch. All nitches around here have a bonding lug
on the outside. Now that I understand what I need to do to get things sealed I will find or make tools for the task. Thanks again.

I use a cord stopper in the conduit & a little bit of pool putty around the braised fitting to ensure the leak is sealed. Most of my leaks come
around the male adapter where the female threaded fitting is loose from bad chemical management.

Do no use butyl it does not adhear/stick to the housing very well use andersons 5min quik set underwater epoxy $65.00 per case 2parts in one stick
works great saves time and $$$$

The butyl works very well inside the conduit. Epoxy is the way to go if strong adhesion is required.

Another (bad) idea
I had one repair service tell me that they use a can of high expansion insulation foam. They blow that into the conduit and voila, no more leak.  But when I asked about light or liner replacement the reply was that they
were there to repair the leak and were not concerned about what the future may bring. Nice guys!!!

light conduit leaks
I have always used Epoxy Bond two part epoxy to seal leaking conduits and have had fantastic results. I have seen the rubber "stoppers" that have
cuts in them to allow for the cord and ground to go through and plug the conduit, but still opt for epoxy. Silicone should never be used for any
underwater repairs as it deteriorates over time and makes an epoxy repair more difficult to bond to the material being sealed.

Light Repairs
Snak23 & hap:
I use a combination, both are from Anderson's. Start with a 4 " strip of butyl tape. Wrap it around the rubber cord in the back of the light niche.
Work the tape tight & force it up the conduit still wrapped around the cord. Then cover the opening with the epoxy putty(5 min quik set)&
rerally work it in tight as well. Give it at least 10 minutes to set before attempting to coil cord back in the niche. If I can I will even leave it
longer to set.

Light or leak repair
You can use a product called ArmorGuard underwater leak repair kit. its a 2 part epoxy, odorless and non toxic, I have used it on many pools and
never had to go back once. www.ecosmartepoxysystems.com for more info on it.

Toilet bowl wax. the 2 part putty is the best. but toilet bowl wax is great for the fact that if you go to replace a light or a liner down the rode
you don't have to worry about the removal. it's such a simple thing but effective. it is better to remove the wax from the ring and put it into a
contain before you go to a customers pool though. looks more professional if you ask me

2pk epoxy offers at the most a very rigid non flexible seal, if packing it around a cable, the cable needs to sit stationary for at least 24 hrs
before the light is fully reinstalled,...
Here in australia, i use a marine grade sikaflex that can be applied and squeezed into conduit and around the cable at the wall. This offers a highly
durable and flexible seal. I also use a product called Emmerkit 2pk epoxy, but i either return to the property at an extra cost or instruct the pool
owner to re-install the light once it has cured.

Cord stoppers cost about $3.50 use on every new light installation. Great insurance at a cheap price.
