However, cracking up a generator or a chainsaw even during the daytime will get campers upset.

Furthermore, a noisy water pump is a common complaint among RV enthusiasts. Some manufacturers tend to use cheap pumps and installation methods to reduce cost, but this will result in floor vibration and chattering pipes, increasing noise while RVing. Therefore, soundproofing a water pump is essential while camping to enhance the whole RVing stay. With that said, in this article, we shall be taking you through some cheap soundproofing tips.

Soundproof a Noisy RV Water Pump

When soundproofing your RV water pump, you will not have to invest so much since the whole process is simple and highly affordable. According to most manufacturers, a pump should not be noisy. However, if it is noisy, it is due to incorrect or poor mounting or set-up. So to fix this issue, here are cheap soundproofing tips you should consider.

Soundproofing Your RV Water Pump In a Few Easy Steps

Step 1: Make Sure Where mount the Water Pump is not Hollow

First tap the surface on which your pump had been mounted with your knuckles. If it sounds like drum, then it will end up acting like a drum by enhancing as well as amplifying the hammering effect of water pulses. Some RVs have this issue; however, fixing it is relatively straightforward. All you will have to do is separate your water line from your kitchen base’s skin. You might consider remounting your water pump on more solid ground.

Step 2: Use Carpet or Foam Rubber to Insulate

Take a piece of carpet or a layer of heavy-duty cell foam rubber and place it between the mounting surface and your water pump. This will help absorb the sound of the pump. Furthermore, you should consider putting a layer of carpet under the mounting bolt’s head to help in enhancing insulation while reducing soundproofing at the same time.

Step 3: Make Sure to Not Over tighten Your Bolts

Avoid over tightening your mounting nuts and bolts. Usually, a water pump will come with a soft rubber or plastic mounting feet intending to help in absorbing vibration. It would help if you considered enhancing it using a carpet layer or/and rubber matting. Installing the bolts and nuts very tightly, you will be compressing the materials designed to absorb vibration. As a result, they become hard, which makes them transmit vibration significantly. You should consider using nyloc nuts, and you should install them tightly only to prevent rattling and movement of your water pump. Furthermore, you will need to use the thinnest bolts/screws available in the market. In most cases, they will come with the water pump; however, you should avoid increasing the diameter of your screws’ or bolts’ shank.

Step 4: Use Smooth Curved Fittings Instead of  Elbow

You will also need to avoid using elbow fittings that are close to the pump’s outlet. This is a vital point to note since it will create turbulence in water as well as back-pressure resulting in a significant amount of noise production, which is the last thing you want to hear while RVing. To avoid this from happening, you should consider using smooth curves instead of elbows.

Step 5. Insulate Hoses with Foam Rubber

In case your  water line that goes through your floor or wall, you will need to ensure that it does not rattle. It would help if you considered using insulation or foam rubber to cushion gaps between your floor or wall and the hose. You might also consider using a high-quality gland to help in holding your hose firmly.

Consider using a flexible hose on or close to the inlet as well as the outlet of your water pump. This is essential since even plastic hoses used by John Guest fitting (which is a common way of plumbing RV cars nowadays) is significantly stiff to pass on pulses from the motion of a diaphragm. It would help if you used a soft food plastic hose of length between 300 and 400mm on each side of your water pump, along with a high-quality stainless steel hose clamp at every joint. Go ahead and loop your hose’s length to form a circle allowing it to act as a shock absorber to pulses present in a line. You avoid securing the hose tightly to the structure or chassis of your RV. It is recommended to use a cable tie that has some movement in order to support your hose’s loop and then prevent them from flopping as well as stressing your joins; however, you will need to have lateral movements.

Step 6: Smooth the Water Flow

In case your room has an accumulator tank installed (usually, they are approximately 120 by 200m; however, the size will vary significantly from one brand to the other). This is a tank designed to help in holding water under pressure. Accumulator evens flow of water to a significantly steady trickle from a throbbing flow at your tap due to the pulses resulting from your water pump diaphragm. By smoothening the water floor, it aids in eliminating pulses that result from the hammer effect that is often associated with noise production.

Step 7: Make Sure There is No Air in the System

Ensure that all air has been bled from your system as it might and will also create noise. Nowadays, most water pumps will self-prime and even purge any air present in the pipes
