SEAFLO Accumulator Tank Water Pump Flow Control with Internal Bladder - 125 PSI, 23.5 oz (0.75 L) | Reduces Pump Cycling and Smooths Water Flow for Marine, RV, and Off-Grid Systems

Straight forward installation. Decent quality. Solved severe water hammer issue that was noisy and bad for the system. The pump runs less, is quieter and the flow has smoothed out.

This unit replaced one that was 20 years old, works like the original.

easy install and great product

This is my second pump and bladder tank purchase. Love them. They work well together and the addition of the bladder tank. Slows the pump down to where it barely runs. Makes things quieter and keeps the pressure steady

Make sure that you research your water pump cutoff pressure and then set the accumulator around 3 lbs. lower. This product works wonderfully!!!

I installed the 0.75 liter size SeaFlow accumulator tank in an RV and used 1/2" stainless steel FNPT hoses on both in and out ports. Added a threaded union to connect the output hose line to original water pump output line. The accumulator works as advertised - the water pump doesn't constantly run and it took the pulsation out of the water flow. I set the pressure to ~27 PSI to be 3 PSI under the water pump's cut-in pressure. Even with very limited room, I was able to install the tank due to its small size. It was basically plug-n-play.

Why every larger Travel Trailer or 5th wheel RV doesn’t come with this standard I’ll never understand. For a little over $50 your pump is half as loud, you no longer have a pulse in your water when you turn it on, and you have better overall experience with your fresh water. My pump was mounted in my basement directly under my master bath/bedroom. Anytime somebody ran water the pump would start blasting. The metal sub floor that it was mount to May as well been in my back tooth it was so annoying. Just putting the accumulator on made the pump have as loud. I then hit a rubber pad and larger rubber grommets from tractor supply. After installing the 3/4” rubble pad I put the grommets under each foot. Then I screwed the pump and accumulator to the rubber pad with 1” stainless course thread screws being careful not to screw in to the wood. After doing this it list the other half of the noise. You can run the shower and the water in the kitchen and you never hear the pump from the inside. If I had to do anything over again, I would have gone ahead and bought the 5.5gpm system instead of just adding in to my 3.2gpm. But I’m new all all it seem is like I’ve been spending money on the RV lately.

Smoothed out water flow. Really easy to install and tune properly. Make sure to set it roughly 3 psi below your activation pressure. Keep in mind that while it can be mounted in pretty much any orientation, it is best to keep the inlet and outlet on the bottom such that it will drain and not retain water so that it can be winterized properly in an RV setting.
