How to fix leak in 5k gallon steel water tank on concrete pad

Plastic water tanks are not that expensive. You're right. I was hoping to "repair" the tank but the advice to check the price of new is apropos. A new "plastic" tank seems to be about $2,000. A new "5,000 Gallon Fresh Water Poly Tank" is $2,238.60 he http://www.watertanks.com/products/0005-045.asp Diameter:102 inches; Height:152 inches; Weight:875 pounds; Here's a heavier "5000 Gallon Polyethylene Fresh Water Tank" for $2,000: http://www.gototanks.com/SN5000-Gall...ater-Tank.aspx Diameter:102 inches; Height:153 inches; Weight:1,200 lbs. This low profile "5000 Gallon Black Water Tank" goes for $1,775: http://www.tank-depot.com/productdet...001IW&ref=base Diameter:141 inches; Height:86 inches; Weight:879 lbs. I wonder how long plastic tanks last compared to steel? |

Since it's a flat bottom it may be possible to replace the entire bottom if the rest of the tank is viable. Empty, even a tank that size isn't that difficult to lift. Someone else suggested welding a new bottom on. Do they lift it up with a crane and then cut the bottom off and fabricate a new bottom? Or do they tip it over on its side and weld the bottom on from the side? I wouldn't want it rolling down the hill! |

Assuming you're in CA from the fire protection requirement, here's one link that might be of some interest--they have black poly from roughly the $2k range. http://www.watertanks.com/contact.asp I agree. The original estimate was wrong. The "poly" tanks appear to be about $2,000 (plus California 10% sales tax). From this link, there appear to be only 3 manufacturers (Norwesco, Inc. of St. Bonifacius, Minnesota, Snyder Industries of Lincoln, Nebraska and RMI in Gardena, California). http://www.winebusiness.com/wbm/?go=...e&dataId=50707 They advertise a one to three year warranty for the poly tanks but say they can last 15 years or more. The tanks I have are welded painted steel, not corrogated or galvanized. Looking that up, it appears the major players are "All State Tanks" of Grove, Oklahoma, and "Columbia TecTank" of Kansas City, Kansas, both of whom mostly erect the tanks in the field. The web site above says "A 5,000 gallon steel tank may cost $3 per gallon" so that's what the well guy must be talking about when he told me it would be $20,000 to replace my 5,000 gallon steel tank. |

send me photos and I'll coach you from there... Hi Jim, I'm gonna take some pics in the daylight and send them off to you (and maybe post them somehow) but that's a GREAT idea to see if I can put a bladder in! You can see the tanks from Google maps so I'll give you the coordinates but they are too tiny on google to discern much other than they are there. |

I can't figure out how one would go about fixing this kind of leak. If it's that small a leak, and the surrounding material is in good shape, they make screw-in patches for those. That's yet another potentially viable solution. So far the solution might be: 0. Empty tank and look for the hole on the bottom 1. If small (pin hole size), use a screw-in patch from the inside; 2. If larger, weld a patch plate from the inside; 3. If too large, consider if they make tank-repair bladders; 4. If not, lift the tank, cut off the bottom, & weld on a new bottom; 5. Or, replace the steel tank with a new "poly" tank. |

A simpler method would probably be to just gradually jack it up a couple feet on cribbing and then work on replacing a section at a time, moving the cribbing as needed, since the replacement metal will be likely be in 4x8 sheets. |

On Wed, 13 Jan 2010 09:52:51 -0800 (PST), DD_BobK wrote: The tank is on wood slats, are they on a concrete pad? * Yes. The concrete pad is about 20 feet long by about 10 feet wide and it has the two tanks sitting on it, side by side, with a small well house off to one end where there pressure pump resides and the top of the well sits along with three or four electric panels. Why do oyu need 5000 gallons? *Or do you need even more? * Something about fire fighting? I think 10,000 gallons is about right for the house. All the neighbors seem to have larger sets of tanks than just two. I misspoke before about the 10,000 gallons needing special earthquake floating pads; it's anything over 5,001 gallons which needs the special pad so that's why everyone has sets of 5,000 gallons. Now you mention that perhaps fittings are leaking and not the tank. I was hoping it was the fittings but when I asked the well guy, he said the only fittings were those I could see on the sides and top of the tank: 0. Tank 1 is leaking; tank 2 is connected to tank 1 by a 4-inch valved pipe 1. The well pumps water into the top of tank 1 via about a 2-inch line 2. The water comes out of tank 1 at about the 1/3 level for the house 3. From there, the water goes to pressure pump and a blue pressure tank 4. From the blue pressure tank, the water goes into the house 5. Additionally, the 4-inch line near the bottom of each tank goes to an unpressurized fire hydrant called a "wharf hydrant" by the fire department None of these fittings are leaking. I was hoping there was a 'drain plug' or something on the bottom of the tank but the well guy said it would just be a weak spot to start leaking. The tank may only be rusted externally, poor maintainance? Maybe the leak saturated the wood slats and promoted external corrosion? Certainly it's not helping the situation that the wood slats are constantly wet. The details are coming out bit by bit. Now there is a second tank? How long have the neighboring tanks lasted? Very good question! This house is 20 years old and I'd guess the other houses are similar since I saw a map from the 70s which didn't even show a paved road. Most houses here are probably less than 20 years old. I will see if I can ask how long their tanks lasted, but some seem to be made out of wood (at least on the outside) and some are green plastic with awnings over them (mine is painted steel with no awnings). Galv steel can last a long time with non-corrosiove water quality. With all that rust on the inside, I'd suspect it's not galvanized. I wonder how else I can tell? If the tank is sound except for the bottom (as per other post) it "could" be reworked. * A skilled welder could rig this thing, cut the bottom off and repair but field repairs are hard to make as good as new factory fabrication. * Interesting idea! I hadn't thought that they could "cut the bottom off". That would solve the problem, wouldn't it? One problem is that it must be darn hard to get heavy equipment up the hill where the tanks are, but, they must have gotten the trucks in there somehow. The well guy things they went from the neighbor's yard. Nobody, until you, suggested cutting the bottom off. The previous idea was to patch it and I understood the problem of "patching the radiator". But, if we can cut the bottom off, then it seems to me the results should be pretty good, right? Call around and see if a welder can "do it all" .....don't drag the guy out there for a bid, you'll be wasting his time. Have all the details (measurements, installation, etc) so you can answer his questions on the phone. I will do that. I guess I also need someone to "tip" the tank over so the welder can work it on the side, right? Check out new tanks online....delivered, I'll bet (unless your in BFE) less than $3000. Installation extra. I will report back. Would you suggest I research steel (1:1 replacement) or some other material? I see wood and plastic tanks all around the hillside.. With the price of a new tank (with installation if oyu cannot do it yourself).......you'll know if a repair is worth while I see the plan. a) Get a rough phone-call estimate from a welder for a new steel bottom b) Get a rough estimate for a new tank from the Internet c) Compare & decide What is your well production rate? Not good. The well guy tested it at 400 feet deep and he ran the well for an hour and it shut off twice (he had to flip the breakers on and off to restart the pump). He said the water level dropped 15 feet in that hour and that we were getting only about 6 gallons a minute (I can double check the paperwork). But if you're going to own a property with a well, better plan on getting handy or keep that check book ready. I'm ok with learning. That's why I'm here asking and responding! OP- I cannot take credit for being the first one to suggest cutting off the bottom. Jim (the professional welder) suggested it & in a subsequent post he offered to coach you on the repair. Please find a photo positing site & post some photos (a couple overall installation views & some detailed ones) so everyone in this NG can see what's up. Approximateing where is this property? San Diego county or NorCal? I'm no well expert but dropping 15' in an hour to supply 360 gallons seems like a lot BUT you probably need 400 less than that per DAY. If oyu want to struggle by for now...get someone to re-pipe (or do it yourself) the pump output so you can fill either or both tanks at your choice (valves in the pump line at ground level that feed each tank) Isolate the leaker and only fill it in fire season for the next year or so while you save money for the repalcement. cheers Bob I think most of the guys in this NG participate as much learn as to help...see new & different problems and their solutions help us all. cheers Bob |

I'd guess there are a number of other suppliers as well; there are several more in this area than those because of the demand for ag use tanks; depending on where in CA you are I'd expect the same for that purpose or for the specific purposes/needs you outline. As for the various other options -- I'd still say odds are quite high that the cost of either the bladder if available or rigging and welding a new bottom will approach or exceed the cost of new poly tank. It's always worth a shot to see if can use the temporary patch that could extend the life somewhat. My luck in welding on thin bottom of the smaller round tanks we use (for hauling water for cattle on pasture) has been mixed--some have turned out so thin burned thru and was given up on and others still had sufficient overall material w/ just a few pinholes. It'll all depend on what actually find if go in. One thing wrt the longevity of the poly tanks -- I presuming you're in warm weather country otherwise you would have icing problems w/ them just outside w/ above ground piping. If so, the primary problem is likely UV even w/ the black poly; since these are stationary application you could undoubtedly extend lifetime by putting under roof and sun shade on south/west sides to minimize that cause for deterioration. -- |

I've had HUNDREDS of radiators repaired over the last 30+ years and not a one of them ever developed a leak in another spot. Depends on what caused the leak. MOST radiator leaks that respond well to repairs are mechanical damage or joint failure. Repairing the mechanical damage or resoldering the split joint USUALLY make the rad virtually as good as new. If a rad has corroded through from both sides and the fins have fallen off, soldering up the resulting leak is a stopgap repair at best. Same with a water tank. A pourous weld? - fix it and it will LIOKELY last a long time. A stray bullet went through it? Fix it and it will last a long time. A rust blister due to damaged anti-corrosion coating on the outside (like paint)? Good chance a repaior will last. If the tank has corroded badly from the inside out, patching one hole may well be the first of a LONG string of repairs, few if any of which will be "successfull" |

A man who ran a water works told me this solution when bottom of a steel tank has rusting, becomes thin and begins to seep: Fill the bottom with concrete at least six inches deep. After the concrete dries throughly, then you can apply a "Rubberize it" coating to the concrete and where the concrete meets the sides. "Rubberize it" is available on EBay. According to the manufacturer, this product is good for potable water repairs.Hope this will help you

How to fix leak in 5k gallon steel water tank on concrete pad
If the leakage is from different places at the bottom, then the best way to stop the leakage is either to get fix one steel plate as of the same size at the bottom or change the bottom with new one and this will certainly solve your problem. http://www.greatbasinindustrial.com/...nd-alterations

How to fix leak in 5k gallon steel water tank on concrete pad
No idea on stopping your leak, but I'm curious about your water quality.
Water goes bad when it sits around. It grows bacteria, slime, all sorts of nasty stuff. In your setup the bottom third of at least one tank never drains. Sounds like a recipe for a fungus amongus. Do you disinfect anywhere? I wouldn't have any qualms about drinking well water direct from the well, provided there's no local contamination. Water that sits in a storage tank is a different story. |
