A motorhome accumulator, often referred to as a "water accumulator" or "pressure accumulator," is a component used in motorhomes to help maintain a steady and consistent water pressure in the plumbing system. It is a device designed to store and release water under pressure, ensuring a smoother and more consistent flow of water when taps or appliances are used in the motorhome.

Water Pump:

Most motorhomes have a water pump that draws water from the freshwater tank and pressurizes it to flow through the plumbing system.

luctuations in Pressure:

Without an accumulator, the water pressure in the plumbing system can vary as the water pump cycles on and off. When the pump is on, it pressurizes the water, but when it turns off, the pressure drops, which can lead to surges of water or uneven flow at the faucets and fixtures.

Accumulator:

The accumulator is essentially a small tank filled with air that is connected to the motorhome's water system. It sits between the water pump and the rest of the plumbing.

Storing Pressure:

When the water pump is running, it pressurizes the water in the accumulator tank. The air in the tank acts as a cushion, absorbing the pressure and storing it for later use.

Smooth Flow:

When you open a tap or use a water appliance (like a shower or toilet), instead of the water pressure dropping immediately when the pump turns off, the water is drawn from the accumulator tank first. This results in a smoother and more constant flow of water, even if the pump cycles on and off.

 The motorhome accumulator helps reduce the "pulsing" or surging of water that can occur when using water in a motorhome. It provides a more consistent and comfortable experience for those living or traveling in the motorhome, particularly when it comes to tasks like showering or washing dishes. It also helps to reduce the wear and tear on the water pump by reducing the frequency of its cycling.

Space and Installation:

Installing a motorhome accumulator can require some space in your RV's plumbing system, and you need to ensure proper installation to avoid leaks or other issues. It might not be suitable for all motorhome setups.

Cost:

Accumulators come with an additional cost over a standard motorhome water system. While they can help save water and extend the pump's life, you'll need to weigh the upfront cost against the potential long-term benefits.

Maintenance:

Accumulators may require occasional maintenance, such as checking for leaks, adjusting air pressure, or replacing components over time. This can add to the overall maintenance of your Motorhome.

Limited Capacity:

Accumulators have a finite capacity, and if you use a large amount of water in a short period, you may still experience pressure drops or pump cycling. You'll need to choose an accumulator with an appropriate capacity for your needs.
