Is there a way to temporarily fix leaking fittings?
Yes. Your best option is to use fiberglass repair tape. Find the problematic fitting, start wrapping the tape at the outside of one side of the fitting and continue wrapping until you’ve gone one inch past the other side of the fitting, onto the pipe. The other technique to try involves plumber’s putty. Sometimes you can apply putty around a loose fitting to solidify the seal and rebuff any leak. It’s the same principle as tape only it will probably be easier to apply in tight spaces. If your fittings and pipes are corroded, these techniques may only cause the problem to move further down the line. Your best bet is to have your system inspected by a qualified plumber.
