Leaks are frequently caused by over tightening, so this is certainly a possibility in your situation. Here are my suggestions: Replace the nut and ferrule. The ferrule gets deformed when compressed, so a new ferrule won’t have the deformations from the previous valve.
What happens if you over tighten plumbing?
Over-tightening will also warp the rubber fittings inside the pipes over time, which can increase the risk of leaks. Turn a plumbing fitting only until you feel it tighten, then stop. Continuing to turn past that point can lead to trouble.
Why does my compression fitting keep leaking?
Over tightening a compression fitting can also cause the fitting to leak. When tightening up the compression fitting, only turn your tool until you feel resistance. From there, you shouldn’t turn it anymore than a half a turn. By doing this, you can ensure you’ll prevent your compression fitting from leaking.
Can you over tighten water lines?
Do not overtighten the supply line.
Such overtightening will cause the metal threads inside of the line to become warped, making it much easier for water to slip past. It may also damage the rubber O-rings inside of the line.
How much does it cost to tighten a pipe fitting?
They should be hand tightened and then another 1 or 2 turns, but no more. More turns will put to much pressure on the fitting and may crack it and cause a leak.
How tight should toilet water line be?
One of the biggest problems when swapping out water supply lines is knowing how tight the connections should be. Obviously this is important to prevent water leaks. Most directions say to hand tighten then use a wrench for the last 1/4 to 1/2 turn.
What is the most common cause of leaking compression fittings?
It is critical to avoid over-tightening the nut or else the integrity of the compression fitting will be compromised by the excessive force. If the nut is overtightened the ferrule will deform improperly causing the joint to fail. Indeed, overtightening is the most common cause of leaks in compression fittings.
Can you use plumbers putty to stop a leak?
Plumber’s putty may only be used to prevent or stop leaks in specific areas. It shouldn’t be used interchangeably with other products such as caulk or tape. … Plumber’s putty has it’s primary purpose as to create a secure seal between a faucet and a kitchen counter-top.
Can you reuse compression fittings?
Reusable Compression Fittings:
They are safe to be reused and apply to half the movement of the pipe outward from the fitting. In hydraulic process, compression fittings basically assure some secure fit in pipe connections. Leaks are only possible if they are not properly installed to each end of the fluid line .
How tight should you tighten compression fittings?
Really you should only tighten a compression fitting about 1.25 turns, but I like to do turns in small increments and check for leaks after each turn. You can always tighten a compression fitting more, but you can’t un-tighten a compression fitting.
How much pressure can a compression fitting take?
Compression fittings are the perfect choice for high pressure applications. In combination with a high pressure tubing material like steel, large compression fittings can often be used at pressures in excess of 10,000 psig.
Can you over tighten a flare fitting?
Fourth, don’t over-tighten the flare fitting, as this can cause leaks. Daikin offers preset flare torque wrenches that will allow you to properly tighten the flare fitting without over-tightening them. Always use a backup wrench when tightening any flare fitting.
Will a slow leak seal itself?
And yes, a slow leak CAN stop on its own. This is especially true if you have a high mineral content in the water.

Does Teflon tape stop leaks?
Teflon tape will help prevent plumbing leaks. Teflon tape is an absolute essential for most plumbing projects. Its physical composition allows it to fill pipe threads and fitting threads with a sealant that will prevent water from leaking through the thread connection.
Are compression fittings reliable?
Although compression fittings are generally considered more reliable than threaded fittings, there are some potential problems. In general, compression fittings are not as resistant to vibration as soldered or welded fittings. Repeated bending may cause the ferrule to lose its grip on the tube.
Are compression fittings as good as solder?
Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.
Do you use PTFE tape on compression fittings?
Can I Use PTFE Tape on Compression Fittings? No. PTFE tape is not designed to seal compression fittings and is ineffective at doing so.
Do I need Teflon tape on faucet supply lines?
You don’t need to connect the faucets to the water supply lines if they have hot and cold lines. Teflon tape can be used to seal and lubricate threaded pipe joints.
Can overtightening cause leaks?
If a valve is over-tightened, it deforms the tubing and the connection. These deformities create cracks and gaps where the fluid can begin leaking out.
How often should you replace braided water lines?
Study recommends replacing stainless steel braided hoses and rubber hoses every 5-7 years. The most common place where a washing machine hose leaks or breaks is the connector.
