epoxy for chemical tank

garyw · Dec 5, 2010

If the hole is threaded, just buy a plug to screw in it. If it is threaded use it and don't worry about leaks. The only time you worry about leaks is if it has a gasket between the tanks and any fittings you use.

I just recently purchase a chemical 110 gallon chemical tank, At the bottom of the tank it has a port hole! I was wondering if anyone has used an epoxy to patch up a port hole, and if so what is the best epoxy to use that would withstand 110 gallon of liquid with chlorine..

I would like an epoxy that would last for ever, with no worries of leakage in the future.

Thanks

TBD - can you post a picture of the port hole? Might help to see what you're talking about.

It does have a rubber gasket in between, and I really don't have any reason to use the bottom port hole.
Being my extra chemical tank i figure it will become a big issue in my cargo trailer some day...
here are the pic i took to give you a better idea why i'm concerned..

Thanks

My tank is similiar to yours but it came with a valve at that location. I was thinking of using it to recirculate somewhere down the road.

That's definitely a bulkhead fitting, cut through the tank and not one that's made into the tank. Its gonna leak sooner or later, just prep for when it does. Keep an eye on it and fix it when it starts leaking. you could seal the floor of the trailer with some truck bedliner like discussed in this thread:

I did a quick search on bulkhead fittings and found this thread where Chris T mentions Viton seals, but also says it will leak eventually:

So the epoxy idea will not work? or no one has tried it as of yet?

2 yrs ago I put a 2 inch valve on mine and I have never had a problem with it leaking, Its actually nice for when i have to rinse the tank....

Hey, we would all like a new tank, but WTF ? ya got a deal on this, and since it already has the bulkhead, just get you a new one like a Heyward with Viton Seals and go for it ?
Like joe says, just keep an eye on it, because it will leak eventually, but it could be a year or more. I see so many people trying to be "perfect", and guess what ? The roof could care less if you pull from the Top, or from a Bulkhead

I sprayed roofs for years with a garden hose, w/o even a hose reel, with a donated chemical tank from some guys back yard. It was FULL of mosquitos and larve too, and very nasty. I spent a full day just cleaning and mounting it to my little trailer, that I pulled with my personal car.
I was poor, but I was CLEAN, and what little I did have was organized and as professional as I could afford to make it, at the time.

Remember, we all have to start somewhere, and you can get "perfect" later biggrin

I called 2 manufactures, They claimed really nothing will bond to the poly tanks.
So I'm going to wish myself some luck and go forward on using this tank and hope i won't get any future leakage.
First thing come first, unbolt and pull everything out of my trailer and rhino seal the floor and min.. three feet up! Just in case i get a leak.....oh and buy some extra viton sealing washers lol

That's for the feed back guys

I have had tanks "fixed" well enough for water by using a router to burn a plastic disc into the leak. They never lasted more then a few months with chemicals.
Seek out a new PVC or CPVC Heyward Bulkhead with Viton O Rings, do not accept or settle for less. You will be fine, just keep an eye on it

Thank you very much for all your support and information, For the amount of time of doing research searching in this forum and the knowledge I have learn from RCIA makes it all worth it....
I'm so impatient , (got me the roof cleaning itch )can't wait till spring comes..
once again thanks for the feed back on some strange question I may have ask..

Amen Chris. You have to start somewhere. One of these days I'll post my first set up.

I see it has a bulkhead fitting. Replace the bulkhead with a PVC Bulkhead and plug it with a PVC plug. Use teflon tape on the plug and do not over tighten it as it will eventually cause the bulkhead to crack. Our 220 gal. tank has lasted 2 years with no leaks.

They are very easy to change. If you have and old wand that is no longer in use, you can bend the end about 8" from the end to form a 45 angle . Guide it into the tank and through the opening in the bulkhead fitting. With a pair of pliers, grip the threaded portion to secure the bulkhead from turning a loosen the exterior nut (reverse threads). Push the fitting in on the rod used a pull it up and out. Reverse this method to replace a new bulhead.

Good question Steve. It's good that you asked rather than just using that old fitting already in the whole. Chris' suggestion will get you ready to roll.

Thanks guys, I'm good to go! Until it leaks that is lol

Appreciate the help.
