Steps On Fixing RV Fresh Water Tank That’s Overflowing
1. Check If Water Pump Is Set To “On”
It’s important to look at the water pump first.
The water pump can get into a situation where it’s inefficient and does not work as you want it to. You will want to take the time to see if the water pump is set to “On” and is stuck in that position.
This does happen from time to time.
When the water pump does not change, it is going to create issues with the RV fresh water tank. It will cause it to overflow.
A functional water pump is not supposed to do this.
It should have a sensor that is going to pick up when the water should stop pumping. This is based on the water level in the RV fresh water tank.
When the water pump in the RV does not do this, you are going to end up with the issues you are noticing right now. This is not good for the tank or the rest of the RV.
You will end up dealing with significant water damage and this is not good for the RV.
Always check the water pump to make sure it is picking up when the water level is too high or low.
2. Inspect The Valve
You are also going to want to take a look at the water valve.
This is a valve that is responsible for the flow of the water in the tank. If there is something wrong with the valve, it will get stuck.
This means it is not going to close as it needs to.
This is going to continue to push water into the tank even when it is not required. This is a similar problem to the one where the water pump continues to run when it shouldn’t.
You will want to look at your options to figure out what has to be done to get the tank to work as planned.
3. Look At The Water Level Indicator
You are also going to have to look at the water level indicator.
The water level indicator is integral to how the pump functions. This is a real concern if the indicator is saying one thing and the pump continues to run in the background.
It is common for the indicator to accurately state how much water is in the tank.
If the indicator is off, this is going to confuse you. It will not be easy to pinpoint how much water is in the tank or what you have to consider to ensure it’s in good shape.
4. Check For Leaks
This is one of the more concerning issues when you are dealing with an overflowing RV fresh water tank.
This indicates significant damage that will worsen if you don’t get on top of things.
The issue could be a potential hole or crack in the tank. This is going to cause water to go where it shouldn’t and that will make it appear like it is overflowing.
You could have water coming into the tank faster than it needs to.
This might seem normal at first but it will get worse as more water enters the tank. This is a sign you will need to figure out what has to happen next.
Final Thoughts
Why is my RV fresh water tank overflowing?
When the RV fresh water tank is overflowing, it is commonly due to the water pump running non-stop or the water valve getting stuck in the on position. If not, it might be a leak or the water level indicator is inaccurate.
It’s best to work your way through these potential issues to see which one applies to your RV. You will want to make sure to address this as soon as you can to avoid long-term concerns.
