How do you seal a leaking pipe joint?

Tighten compression fittings firmly with two wrenches to crimp the ferrule onto the pipe (Photo 3). Also make sure the pipe or tube goes straight into the fitting. Misalignment will cause a leak. If the fitting leaks after you turn on the water, try tightening the nut an additional one-quarter turn.

Is Cast Iron Plumbing bad?

While it can be more brittle than pure iron, it is extremely durable and can withstand high amounts of pressure. The downside of cast iron pipes is that they are susceptible to corrosion (rust), which causes 25% of pipe failures. Depending on the environment, corrosion can damage pipes in as little as 25 to 40 years.

Can cast iron pipes corrode?

When cast iron waste pipes fail, it's usually due to corrosion from within. As a result of what runs through waste lines, hydrogen sulfide gas can form. This can oxidize and produce sulfuric acid, which corrodes cast iron. As the iron around a pinhole rusts, the iron expands and seals the leak.
