We are Going to Elaborate the Solutions for you in this Part
- If your valve is pretty old, replacement would be the only option.
- If the drain valve remains open, consider closing it and checking again.
- Check whether the fittings are loose or leaky.
But how can you tell where it is leaking around the fitting? Close the valve all the way, dry everything off and check the leakage area. Whether it is the valve itself or the area somewhere around the valve.
- You can fix these leaky fittings by adding solder that needs no welding around the valve. Now if the valve is leaking itself or no more usable, you gotta replace it.
- You might be wondering if the above process is expensive. Well, no!
- Just drain it in a planned fashion from the drain valve. Or else it might get worse and you end up having an unexpected puddle on the floor.
Water could be dripping from the temperature-pressure relief valve. In that case, you need to check the pressure.
- If the pressure is high enough to force it to leak from other valves, that would flood and cause a dangerous situation.
- So you must check that the valve is shut all the way while there are no red warning lights flashing on the control panel.
- If you did not replace the valve for a longer period, rust inside and around the drain valve might develop.
- In some cases, the sediment gets so bad that you cannot drain it through the drain valve. Hence, replacing the drain valve periodically can save you from all these troubles.
How To Fix Your Boiler Drain Valve Leaking?
The easiest way to notice the boiler relief valve leaking water is that the nipples would be coming off of the copper valve.
Follow these steps and see how to fix the boiler drain valve dripping.
- While taking the valve off, make sure not to twist it. Instead, just hold it below. If you twist it, you can end up twisting the pipe off, thereby leading to a mess.
- If there’s no flat spot, use channel locks to make a grip. The channel lock has teeth cut in it. That will cause it to grip in one particular direction and slip in the other direction.
- Grab the channel lock and pull it in a way for the stair teeth to grip. So pull it upward and use a wrench for turning the fitting in the other way.
- Now holding the wrench, twist it, and reverse until the fitting comes out.
- Then you will notice the boiler relief valve keeps leaking. Turn the water off.
- Time to replace the new fitting. Put in just a simple half-inch boiler drain. You will get these at a hardware store.
- Wrap some Teflon tape. Teflon tape wraps the loose threads by filling up the space between them to tight grip.
- When you turn it clockwise to tighten it into the fitting, you want the Teflon tape to slide with it, instead of rolling up in a ball. So with your fitting pointed upward, you are going to start it on the bottom and run it around.
- Roll it around at least three times. You will notice the Teflon tape pulled up along and not get bunched up. In this regard, make sure to put it in such a way that when you screw it in, it drags instead of dragging it. We recommend using a little bit of the pipe thread sealant to seal.
- Now go back to your fitting and finish the threading by hand. There will be water dumping out.
- Install your new fitting right away. Use your hand in this step. That way, you don’t have to cross-thread anything.
- Now tighten it in the same procedure as we have explained earlier. Tighten them until they are pretty snug.
- Turn the water back on. If water is still leaking, try tightening them again. If it still doesn’t fix, take them back out and reapply the Teflon tape and thread sealant.
