SLOW OR FAST AIR LEAK
It is considered a SLOW leak if the gauge indicator drops to level 2 or level 1 a few hours after the pressure has been brought up to paddle or tennis level. If the gauge drops rapidly, after a few minutes, it is considered a FAST leak.
We will now analyse the problems according to the type of air leakage and their solutions. This will help you to get to know your unit better and resolve any issues simply and quickly.
Choose one of the following options (although we recommend that you view the entire guide so that you are fully aware of the features and operation of your 3B or 4B unit)
considered slow when the pressure gauge drops to position 2 or 1 after a few hours
This is the most typical cause of slow leakage and is very easily solved by following the simple maintenance instructions.
Proceed to clean and lubricate the o-ring. This is the normal maintenance process that should be carried out periodically.
If the system has not been used for a long time, the o-ring has probably dried out and stuck to the container. This o-ring has already deteriorated and needs to be replaced and re-lubricated.
Make sure you purchase the right o-ring for your system depending on whether your unit is:
- Black color 3B
- Transparent 3B (version 2021 onwards) or 4B
Sometimes it happens that we don't close it enough. Follow the instructions in the video and find the right point of your unit
t can happen that the pressure gauge has unscrewed a little or that it has suffered a blow when using the inflation pump or due to some other cause. other reason, causing a small displacement and breakage of the cap thread.
Detection of the possible leak:
To detect a possible leak at the base of the pressure gauge, use a little water and look for bubbles that give away the leak.
Be careful not to pour water over the gauge or submerge it. A thin layer of water is sufficient. Wait a few minutes, the bubbles may appear quickly or one by one and slowly.
- Screw down the pressure gauge a little (about 5-10º) without forcing it. If this does not work, perform the following step.
- Unscrew the pressure gauge and put some teflon tape on it (only 3 turns of teflon)
- If all of the above does not solve the problem and we still have a leak, it means that the thread of the cap has broken and the whole cap needs to be replaced.
To fix it you will need to buy a new complete cover here
- Knock or fall: if you drop the container on a hard surface it may cause a crack, usually on the underside of the glass.
- Thread breakage: occurs when grains of sand from the track or other hard elements get lodged in the thread and when closing the tumbler, this foreign body causes the thread of the container thread to pop out, causing air to escape.
- Factory defect: the container is manufactured by injection moulding and in this process a very low percentage can be defective, with a crack appearing on the bottom of the container.
How to detect leakage:
- Try to locate the crack visually by looking for irregularities on the bottom and thread of the container. If you find any, pay special attention to that area during the next step.
- To detect leakage at the bottom of the container put pressure on the system and immerse the bottom of the vessel in a container of water (a few centimetres of water is enough, NEVER immerse the whole lid, you will damage the pressure gauge)
- If there is a crack and air leakage, bubbles will come out continuously (more or less slowly)
- To detect leakage in the threaded container, apply pressure to the system and vertically submerge the Pascal Box until the water covers a couple of centimetres of the lid (NEVER submerge the entire lid, you will damage the pressure gauge)
- At first, bubbles will come out because of the air between the lid and the container. This is normal and does not mean that there is an air leak. Slightly tilt the container so that all the air can escape.
- Once all the air has escaped, if there is a crack in the thread of the lid and there is a leakage of air for this reason, bubbles will escape continuously (more or less slowly)
- If the leak is in the lower part of the container and you believe it has not received any blow, send a message to firstname.lastname@example.org or whatsapp to 918 812 271 indicating that you have carried out this leak detection process and include a good photo showing in detail the crack, date of purchase and photo of the purchase invoice. Our support service will quickly check if it is indeed a manufacturing defect and will give you instructions on how to proceed to send you a free replacement container.
- If the leak is at the bottom of the container as a result of a fall or a blow, you will have to buy a new container here: Buy Pascal Box 4B container - Buy Pascal Box 3B 2021 container
- If the leak is in the thread of the container due to a crack caused by sand or foreign bodies, you will have to buy a new container here: Buy Pascal Box 4B container - Buy Pascal Box 3B 2021 container
IMPORTANT: This only affects versions of the classic black Pascal Box 3B prior to 2021. 3B 2021 and 4B versions are not affected.
It may happen that the safety valve of your Pascal Box 3B Classic has unscrewed a little or that it has suffered a blow when using the inflation pump or for some other reason, causing a small displacement and breakage of the thread of the cap.
Detection of possible leakage:
To detect possible leakage at the base of the safety relief valve:
Use a little water and look for any bubbles that might indicate a leak. Be careful not to pour water over the gauge or submerge it. A thin layer of water is sufficient. Wait a few minutes, the bubbles can appear quickly or one by one and slowly.
- Screw the safety valve back a little (about 5-10º) without forcing it. . If this does not work, perform the following step.
- Unscrew the safety valve and put some teflon tape on it (only 3 turns of teflon)
- If all of the above does not solve the problem and we still have a leak, it means that the cap thread has broken and the entire cap needs to be replaced.
To fix this you will need to purchase a new complete cover here: Complete lid for Pascal Box 3B & 4B
considered fast if the needle drops rapidly within minutes and down to zero level
This is the main and most typical cause of rapid pressure loss, and also the easiest to resolve.
In 99.99% of the cases it is caused by using the tool plug to press down the howitzer to remove the air from the system.
When the tool plug is used to press the core plug (photo of the core plug) it can unscrew causing the leak.
Detection of possible leakage:
Simply put your finger on the valve to see if you can detect the leak or better yet pour some water over the top of the valve and watch for bubbles.
Use the tool plug like a screwdriver to screw in the valve core. Just a little, no need to force.
Now you have discovered the main function of the tool plug. It is designed neither to act as a stopper (which it is), nor to extract the air, but to screw the valve stem of the inflation valve when it is unscrewed. Surprised?
A very useful and practical tool that you should be careful not to lose. But you can always buy it here: Buy Tool Cap for Pascal Box 3B & 4B
CHECK THE REST OF THE COMMON PROBLEMS
This problem occurs mainly with units of the classic black Pascal Box 3B (pre-2021 version) and is caused by one or more of the following causes.
- You have not carried out the necessary periodic cleaning and lubrication maintenance. This causes the gasket to stick to the cup, making it very difficult to open.
- The unit has been closed for a long time causing the gasket to dry out and stick to the vessel making it very difficult to open.
- It is too tight when closing (either by hand or using the easy-open system, which is not designed to close but to open).
- Try to open it using the easy-open system on a metal profile of a door, window or similar. It is very important that you always push against the profile while holding the glass at the bottom and making a slow and gradual counterclockwise turn. If you do not push at the same time as you turn the glass, you may break the lid.
- Try to open it with the help of another person. One of them simply holds the Pascal Box tightly (without turning it) by the lid, and the other person holds it by the bottom and turns it slowly and gently counterclockwise.
- EIn extreme cases it will be necessary to use a special tool such as a vise.
In any of the above cases the O-ring has deteriorated and needs to be replaced.
Once we have managed to open the unit we proceed to replace the seal and lubricate it.
You can buy here the gasket (choose classic gasket if your lid is from the Pascal Box 3B classic black) and the new special lubricant (as a lubricant you can also use normal solid Vaseline)
Buy classic O-ring (PB 3B) + lubricant - Buy O-Ring PB 3B and 4B 2021 + lubricant
Note: As mentioned above, this problem occurs mainly in units of the classic black Pascal Box 3B.
The new Pascal Box 3B v.2021 and the Pascal Box 4B have a new lid, new gasket and are supplied with a new special lubricant which makes the opening much easier when the above mentioned causes occur, and also in normal, everyday use.
The lid with the new design and the special gasket is fully compatible with the classic black Pascal Box 3B tumbler and can be purchased here: Buy Complete lid for Pascal Box 3B & 4B
Pressure gauge does not indicate zero level when the system is depressurised
The pascal box or the cover has been dropped or hit hard and the needle has 'jumped'.
As a result of the blow, the needle is out of adjustment, i.e. the indication on the pressure gauge needle is not correct.
- You must replace the pressure gauge by purchasing a new one here and following these instructions instrucciones:
The top plastic cover of the pressure gauge has fallen off or I have lost it, but it is still working properly.
The system or the cover has been knocked or dropped causing the plastic pressure gauge cover to come loose.
- -f you don't have the plastic cap you can still use it without it (it would be convenient to try to protect it using something that does not interfere with the needle mechanism)
- If you keep the lid you can glue it on using a drop of loctite or similar plastic adhesive.
Note: In any case, if the pressure gauge is damaged at a later date, you can always replace the gauge with a new one here and following these instructions:
