The longer cast iron water pipes are left in the soil, cellar, or crawl space, the more rusted and blocked their joints get. When you have to remove a fitting, it might be a difficult operation.
You might not have needed to remove the spotless plug until the waste stream backed up and there was no other way to access the clog. There is no method other than releasing the screws with a hammer, coming down hard with a screwdriver, and trusting that you will accomplish in the finish.
How to Remove Cast Iron Cleanout Plug
Things You Will Need
- Spray lubricant
- 2 pipe wrenches, 18-inch
- 2 pieces 1-inch steel pipe, 24-inch
- Cold chisel
After buying these tools, your job is started now. So let’s start:
Apply lubricant around the lip of the cap, directing it to get as many necessaries into the threads. Allow at least half an hour for it to absorb before continuing. If it’s truly stuck, 1-Tom-Plumber suggests letting it overnight.
Hit the lip
According to Family Handyman, hit the lip of the cap a few times with a hammer to release the threads.
Tighten the pipe wrench
Screw one 18-inch pipe wrench onto the circular nut in front of the stopper, and another around the drainage pipe. Including one wrench, hold the pipe while turning the nut around with the other.
Adjust the length
Fit a 2-foot length of 1-inch steel tubing over the grip of every wrench to provide significant influence if the nut refuses to spin. While you unscrew the plug, have a helper keep the pipe straight. Disconnect the pipes and start spinning them with one of the wrenches after it starts turning.
Press and hold
Press the appropriate clockwise motion with a cold hacksaw and a big hammer if there isn’t enough space to include a pipe wrench. Put the chisel point as near to the rim’s outside edge as appropriate, hold it at a 45 ° angle, and strike it hard.
- If the tubes are clogged, unscrew the obstruction while wearing rubber gloves and holding a bucket.
- If everything else fails and the plug will not spin, you may need to cut out the whole connection with a hacksaw and replace it.
How do you non-destructively remove a cast-iron cleanout plug from a pipe?
- Discharge plugs in wrought iron pipes are often made of brass or bronze to prevent oxidation and seizing in threaded fittings. Cleanout plugs are detachable, and I’ve never seen one put in a refer joint (which isn’t truly detachable), so you’re probably dealing with a rusted threaded connection.
- Products such as PB Blaster and Liquid Wrench can assist release the corrode; they operate by capillary action to dissolve rust and liberate threads, but they require a while. If you can wet the threads overnight, you should be able to break the trapped plug loose.
- Often these cleanout plugs have a protruding, square knob (others have a recessed hex that requires a specific tool), so tighten a wrench around the plug, apply pressure, then softly tap the edge of the fitting to release the rust. Ease it off, move it back and forth, and add extra penetration oil to the threads if the connection budges and then firms up once.
- The temperature will allow the connection to stretch, and if you utilize this to your benefit, you may be able to wiggle the connection using heat. However, you would not want to make fire, so discard any penetrating lubricant or combustible chemicals, and prevent breathing fumes created while heating.
- Please remember that ancient cast iron pipe is highly fragile, and tapping, twisting, or otherwise applying torque to it might cause it to shatter or cause other connections to loosen, so keep a close eye on the entire situation as you operate.
