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.

Did the job. Added it to the boat fresh water system, the pump noise is too quiet now, hard to tell if it is running. Should have bought the 1l version but space was an issue. Functions right out of the box for us.

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.

Products/vendors start with 3 stars (average) and go up or down from there. This product loses one star because the threads are not true NPT (like with SeaFlo pumps) and the 2 supplied barb connectors are a length hassle when adding a short piece of 1/2" tubing. A one-piece plastic (flex) connector with 2 compression females on each end (like ShurFlo provides) would have been better, especially if using a matching Seaflo pump, as I am. The accumulator arrived in exactly 7 calendar days (and 5 business days) on standard "free" shipping, so that simply meets expectations -- no added or deducted stars for that. It arrived in a priority bubble wrap envelope inside a blister pack that was cracked; but the product was undamaged, so, well ... kinda petty. This item holds its PSI over 24 hours, even after use -- as it should. It pressure-tested well once the connections were firm. My 30/45 pump actually kicks in at 32 and out at 44 PSI, so my accumulator pressure is set at 30 PSI. FYI, simply checking the air pressure can lower it 2 or more PSI, due to the small air volume inside the little unit, so plan accordingly. The new pressure stem seeped some air at first, but eventually broke-in and held well. Coin-operated, preset gas station air compressors are confused by the little unit's volume, so I recommend a conventional air hose method instead. A snug valve cap is likely important for this unit. The accumulator is added onto a complex 1/4" OD plant container drip irrigation setup with 150 emitters, all stepped-down to 25 PSI (post-pump) using a regulator to protect the emitters from spewing. This accumulator was placed inline to stop the annoying pump stuttering while the lines were filling -- then the constant-on when the lines were filled and dripping. How it does: It slows the pump cut-ins to a reasonable degree, but it isn't astounding, due to the small holding capacity of the .75L "tank." But a bigger tank is space-prohibitive. I'd say it went from stuttering 2-3 times per second to on/off every 1-3 seconds -- and running from 1-2 seconds each time as well; but thankfully, the water-hammering wasn't there, which should alleviate some abuse on the entire system. As an aside, if I lowered the pump's cut-in pressure closer to the irrigation system's 25 PSI operating pressure, it would likely increase the pump's rest time as well. But I'm considering eliminating the semi-redundant pressure reducer instead, as the pump system pressure is pretty manageable anyway and this unit will only help that. I'll experiment with it. As a side note when used in this popular capacity, it is better to use 1/4" push-to-connect OD fittings on the MAIN lines, rather than 1/4" ID interior barb fittings, as this allows the pump and accumulator to operate more smoothly and efficiently with better-distributed flow as well -- and as much as 30 percent time savings too. I hope this review helps you folks.

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.

This is the Prefered Accumulator tank used in RV applications.

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

These pumps are great, I live in Mexico and the 'water system' in my house is gravity fed. Not ideal at all, you had to do laps in the shower to get wet. No more. I get excellent pressure now from the shower and the taps, it was, in the shower, cycling the pump a little so the flow wasn't consistent but even at the slack flow it was more than enough. I ended up buying an accumulator tank and that solved the 'problem' that wasn't really a problem in the first place immediately. Worked so well I bought one for a friends house and they absolutely love it... I think neighbors are going to the house to witness the miracle of water pressure from their taps and shows, kind of like the Fatima deal. Well, maybe not quite on that scale but people are impressed. Great products, seriously, easy peasy to install and they have a most excellent warranty, 4 years. Plus the price.. to be honest I wasn't expecting much considering how inexpensive they were but.. far exceeded my expectations. If you have a problem with low water pressure in your house, in your trailer or on your boat this is the solution. 5 stars for both the vendor and the product.

Todo correcto.

Nice price

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

Prix très bon

Pour le moment, produit reçu dans les délais, très bien emballé, très belle qualité, à voir à l'usage après installation.
