The water in your RV’s water lines is under pressure from the city water supply or your own water pump. If there is a break in the line or a valve is left open, that pressure can cause water to spray out forcefully. In addition to causing significant damage, this can be a serious safety hazard.
If you are having problems with your RV’s water lines, it is important to understand what could be causing the issue. One possibility is that the PSI (pounds per square inch) of the water pressure is too high. This can happen if the city water supply to your RV park or campground is too high, or if your own water pump is set too high.
If the PSI is too high, it can cause the water lines to burst and spray water everywhere. In addition, it can damage the fixtures in your RV, such as the faucets and toilets. If you think that the PSI might be too high, you should have a professional check it.
Another possibility is that there is a leak in one of the water lines. This can happen if a pipe bursts or if a fitting is loose. If there is a leak, water will spray out whenever the pump is turned on or when a tap is opened.
If you suspect that there is a leak, you should have a professional check the water lines as soon as possible. Leaks can be repaired, but they can also lead to serious damage if they are not fixed right away.
In some cases, the problem might not be with the water lines at all. If your RV’s plumbing system is not working properly, it can cause water to back up into the RV. This can happen if the sewer line is blocked or if there is a problem with the septic tank.
What PSI is safe to blow out RV water lines?
The safe PSI to blow out your RV water lines depends on the type of pipes you have. If you have PVC pipes, the maximum safe PSI is 60. If you have polyethylene pipes, the maximum safe PSI is 80. For all other types of pipes, the maximum safe PSI is 100.
The PSI rating of your RV water pump can be found in the manufacturer’s instructions. If you cannot find the instructions, you can contact a professional to help you determine the PSI rating.

How to blow out your RV water lines
There are a few different ways to blow out your RV water lines. The most common way is to use an air compressor. You will need to attach the air compressor to the water lines and turn it on. The pressure from the air compressor will push the water out of the lines.
Another way to blow out your RV water lines is to use a garden hose. Attach one end of the hose to a faucet and turn on the water. The pressure from the water will push the water out of the lines.
You can also use a power washer to blow out your RV water lines. Connect the power washer to the water lines and turn it on. The high-pressure stream of water will push the water out of the lines.
FAQs
How can I reduce the PSI in my RV water lines?
If the PSI in your RV water lines is too high, you can try to reduce it by turning off the water supply to your RV or by reducing the pressure on your own water pump. You should not try to reduce the PSI on your own without first consulting a professional. They will be able to help you determine the best way to reduce the pressure without damaging your pipes.
What should I do if I encounter a blockage while blowing out my RV water lines?
If you encounter a blockage while blowing out your RV water lines, you should turn off the air compressor or water supply and have a professional check the lines. They will be able to clear the blockage and help you safely blow out your RV water lines.
