Holes in Cleanco waste tank

[Cleanworks]

Finally pulled the waste tank from my Cleanco to inspect the leaks. Found major holes all along the bottom. Still undecided if it can be welded or if I can apply some sort of epoxy. Will have to be sand blasted first to see all the damage.

What’s that round blue thing?

I had one repaired for $600.00. They added aluminum to the bottom and up the sides 1-ft. That was several years ago and as far as I know it's still holding up.

I thought you of all people would recognize a screw driver.

My fabricator is looking at it. He has a similar idea.

Flex Seal is pretty amazing. I fixed a leak almost 3 years ago and it's still holding.

Hole punch



weld new is the right way for permanent repair
BUTT....I got another couple years out of mine with a $60 (at the time) McPherson job.

Amazon product



taped the holes and poured it in bottom


Flexseal wasn't a thing back then.
or I might of tried it

..L.T.A.

Considering an aluminum epoxy like Gluevit but the bottom is like Swiss cheese. Looking at a proper welded repair first. A couple of holes are larger than 1/4 inch.

Get a Judson with stainless steel tank. Les guarantees for centuries!

 

[Nomad74]

Put a two part epoxy on it, it will work just fine. I would get a marine grade epoxy.

This is going to take more than JB weld or small amounts of epoxy. The bottom and lower sides have multiple holes and many pits that will become holes. Have to sand blast first to see the extent of the damage. Probably going to weld new aluminum to the bottom and plug and epoxy the sides.

Do me a favor.
Just let us know when it’s done.

I see hydramaster installs a sacrificial zinc anode on their waste tanks now. I think anyone with an aluminum tank should consider that.

my alloy tank had similar issues as yours, they tried welding new alloy but kept blowing through corroded areas

I ended up getting new ss tank fabricated instead

I haven't ever had issue with my 'marine grade' aluminium water tanks. My fresh water tanks of the same material are another story. Those are where the sacrificial anodes would be helpful. Softened water destroyed the insides in a matter of a year or so.
In the long run, replacement with a new tank would have been the way to go. I went the ss route for my freshy tanks. I credit the longevity of my vac tanks to our 7.8 ph Roto-Static Cleaner.

Makes me wonder what the prior owner was putting in there. I had one other tank repaired but it was in service for 34 years. This one is only 19 years old. Do acid rinses add to the corrosion? Someone using bleach to clean it periodically?

I think ours was 12 years old or so. I believe not thoroughly washing the tank out and leaving sediment in the bottom damaged ours. ???

Good reason to invest in an inline filter.

We had them. We should have inspected and rinsed them out more often. Fortunately it was the only one we ever had do that. A corner had gotten eaten to the point it was almost as thin as foil.

23 year old tank lid. Inside of vac tank still has white powder coating intact. I purchased a spare AquaTech unit out of BC, and after washing out the insides of the tank of greasy residue, was pleased to find an almost new condition vac tank.
The previous owner must have cleaned a lot of restaurants.

 

[The Great Oz]

Once the metal is that far gone you need to replace. Sandblasting will probably leave gaping holes. I'd cut the bad metal away so it isn't left as lint catcher at the bottom of your newly repaired tank.

PS: Common fix is to weld a tank lid to the bottom of the tank.

 

[hogjowl]

That’ll put a handle on that lint

Only long term fix for that is a welded cap.
