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

I bought this accumulator to try and stop the pulsations of the water pump in my RV. They have smaller versions of this that are about a quart in size. I chose to go with the 2 gallon one. it is obviously larger and takes a little more room in a cabinet but so worth it. Installation was not to difficult, except for working in a cabinet. You will need to buy some pipe fittings to install it also. it worked so good, no more pulsations in the water, just like home. They pump does run longer when the pressure in the tank drops to the cut in point however it does not run as often and turn off and on rapidly with lower water flows. I highly recommend one of these for your RV

My tankless hot water unit wouldn’t work properly due to low water flow, they require a minimal flow rate and my water pump in my RV couldn’t provide it by itself, I ordered and installed this Accumulator tank and it keeps my water pressure at a steady flow rate and my tankless water heater unit is now functioning properly as it should!

Great product. Super happy. The thread is 3/4" MNPT as advertised. Many reviews mention troubles with pipe thread, but a standard 3/4" FNPT to PEX fitting from a local big box worked just fine for me. I've used the much smaller model from their competitor in much more space-restricted camper build. That helped with pump cycling, but this tank changes the game. Flush the toilet and wash your hands - the pump doesn't even kick on. It's only during really prolonged use that the pump is needed. Not to mention the added consistency in pressure. We don't have much use for both sinks and the shower at the same time - but we could if we wanted to now.

Meets form, fit and function. Hope for Longevity .

This pressure tank is used in a weekend cabin. I have a 100 gallon fresh water tank as a reservoir to pump water to a shower and 2 faucets. The tank has a large enough capacity that the water pump doesn’t run continuously. In fact, one or two uses of water at the faucet are possible without the pump on. Not only is that easier on the pump, reducing wear on the diaphragm, it is also quiet. My previous softball size tank had so little capacity, the pump turned on with each use of the faucet. This caused the rv style water pump to wear out after just a year of use.

I wish you could give bonus stars! The old jabsco 12573-2000 accumulator sprung a leak and I don’t think they make that model anymore and I REALLY didn't want to change styles, sizes, or drill new holes. I found this for an absolute bargain compared to the closest jabsco replacement and hoped it would work as it looked identical in size and shape from the picture to the old one. Not only was it physically the same size but even the screw holes lined up exactly the same. The fact that it even has rubber isolators in those screw holes was icing on the cake. The fittings are the easy to use plastic hand screw wingnut style and are extra long. I was concerned about the length difference but when I went to take the old accumulator out, the hoses were stuck. No problem! With the longer fittings I simply cut the hoses off at the old fittings and popped them right on the new ones. It’s like the person that designed this had actually done the job before. If you’ve done any work on a boat, you can greatly appreciate all of those details that make the job that much easier. The standard valve stem and bladder system are an upgrade over the old one as well. All in, it took me longer to gather and lay out all of the tools I was expecting to have to use than to actually replace this part. I want to say it was maybe 10 minutes. If you are in the same boat as I was, do yourself a favor and buy this!

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.

Coupled the tank with the Seaflo pump and it does make a difference. considering a larger tank if available.

Been using for awhile is good quality and works well. We are off grid and set up with rv pump for water in our house.

This little gadget help keep the pressure up and helps the pump work less.

Très content pour mon réseau d'eau de camping car il n'y a plus de bruit dans les tuyaux

Acho bom artigo o tempo o dirá ?

Ich habe den Druckspeicher in einem Forster Campervan / Wohnmobil verbaut. Das war die beste Investition meines ganzen Wohnmobils! Die Druckpumpe springt erst nach ca. 15 Sekunden bei klein geöffneter Mischbrause an. Die Pumpe ist fast nicht mehr zu hören. Das Thetford Klo spült jetzt mit doppelter Kraft. Kein Klackern der Pumpe mehr, kein ungleicher Wassertrahl. Man spart enorm Wasser. Bei mir halten die 90 Liter Frischwasser jetzt viel länger. Man kann viel genauer regeln und wenn man ein "Sparbrötchen" wie ich ist, freut sich über jeden Liter wenn man Autark stehen möchte. Klare Empfehlung, ein günstiges Gadget mit enormer Wirkung.
