my elderly neighbors water heater is leaking where the water pipes meet the heater.it is a slow leak.she can‘t afford a professional .can we resolder the connections without replacing them?
I shut off the Water at the main line s it enters the house. Then I drain the line . Afterwards with a torch I heat the fitting and take it apart. I then clean it of any old solder. I take a piece of bread and roll it into two balls and insert one bread ball into each line to prevent any water drips from leaking out. Make sure to push them in 5-6 inches. Then re flux the fitting and re solder it into place . . Afterwards turn on the Water at the main input valve and the water pressure will dissolve the bread balls . Open the taps and let the water run for a minute so all the bread is gone and Your problem should be solved.
I dig your avatar: Ming the Merciless as played by Max Von Sydow in 1980's Flash Gordon. Loved that movie. Now, to your question: Absolutely. I did one in a commercial kitchen Friday evening. Turn off the water supply and drain as necessary to remove any pressure from the line. You won't be able to reflow the solder in a line that has water in it, so you're going to have to drain enough to get the pipe empty. If there are stop valves with drains, you may be able to isolate the pipe (good luck with that, but it's the Holy Grail when you encounter that kind of forethought). Sand or steel wool to remove any surface corrosion, flux thoroughly and heat the joint. Solder migrates within the joint toward the heat, so get the heat moving deeper into the joint to ensure it's completely filled. You want the heat of the joint to melt your solder, not the heat of the flame. Heat the joint, move the flame away and touch the solder to the joint. If it starts to flow into the joint, good! Now move the heat back further into the joint to encourage the desired migration. Have a wet cloth on hand to cool things off, and maybe a spray bottle to put out any fires you start (it happens). Refill the pipe and test for leaks. If everything stays dry, hey presto! Good job and crack a beer.
Technically yes, but it would really be best to replace the damaged section. If wouldn't take much at all either. Just a small section of pipe and whatever fittings you need. To just resolder the existing pipe, you'd need to heat the pipe, un-do the connection, clean it VERY well, re-flux itit would just be easier to fully replace the fittings.
it would not be cheaper just by the stuff and i would say around 150 because im not quite sure how big a 112 liter tank is and what u plan on using. plus maybe another 35-50 for fish and all the works
