Good adhesive/sealent repaired a furnace condensate tank.
August 6, 2017
I have heard on pretty good authority that Plumbers Goop and Household Goop are exactly the same product in a different tube but you pay a premium for Plumbers Goop. I use both products. Anyway I used this to seal up a hairline crack somewhere in the hard plastic condensate tank of a 6 year old York high efficiency propane furnace. This little reservoir in the furnace holds water and when it gets to a certain level a hose drains it to the electric condensate pump outside the furnace. They were a bad design. It is two halves like a clamshell design joined with self tapping screws but a brittle hard plastic. The mechanical company wanted $400 plus labor to replace the known bad York tank they all get cracks either from over torquing the screws of what have you then water leaks onto the steel floor of one compartment of the furnace and rusts it, and leaks onto the basement floor. Clearly no good. I waited until the furnace was off cut off the power switch and dried the area with a har drier. Then many applications of Plumbers Goop over a period of weeks. It is humanly impossible to find the hairline crack so you have to goop up all the edges basically build a dam out of Goop. I used many wooden coffee stirrer sticks as applicators in a very hard to reach area the back wall of the furnace. Goop needs 48 hours to dry fully. It does have sealant properties as long as the water is not under pressure which this is not. Anyway it seems to plugged the leaks at least to 90% drier than before. It is summer now of course so next winter is the test. But so far so good. Goop is not easy to work with and you need a respirator for breathing. Wear rubber gloves too. It starts out runny out of the tube but quickly forms a skin and thickens up. So sometimes put some on an applicator and let it thicken up a bit. When fully cured it is flexible and rubbery. Anyway Goop has a following because it is a fairly strong adhesive that is also a sealant and has good gap filling properties. You need to put grease on the threads of the tube, else the cap will glue itself on and you will never get the cap off without destroying the tube.
