Having two propane regulators in your setup is not recommended as it can result in low pressure and hinder the proper functioning of your propane accessories. Let me explain why this is the case.
When you use propane as a fuel source, it typically comes from a high-pressure source such as a propane tank or a gas line. This high-pressure propane needs to be regulated to a lower, more manageable pressure before it can be used by your appliances or accessories. This is where a regulator comes into play.
A regulator is a device that controls the flow and pressure of the propane gas. It ensures that the pressure is at a safe and consistent level for the appliances to operate effectively. Typically, the propane tank or gas line will already have a regulator installed to regulate the pressure before it reaches your appliances.
Now, if you try to add another regulator downstream of the existing one, you are essentially reducing the pressure twice. This can result in insufficient pressure for your propane accessories to function properly. In fact, the pressure might be so low that your grill, for example, may not ignite or cook your food evenly.
To illustrate this point, let me share a customer experience. We had a customer who attempted to use an RV gas grill that already had its own regulator, with propane sourced from a tank that also had a regulator. The result was a significant drop in pressure, causing the grill to have difficulty igniting and producing an adequate flame. The customer had to return the grill as it was practically unusable in that setup.
Using two propane regulators in your setup is not recommended as it can lead to low pressure, resulting in poor performance or even complete failure of your propane accessories. It is best to rely on the existing regulator installed on your propane tank or gas line to regulate the pressure effectively.
