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

Does the job , definitely helps, the off brand i had previously only lasted a few months, that's why I've waited almost a year to review this. Has worked well the whole time. Not complaints

Works as advertised, easy install, reduces pump noise, speeds system pressure recovery …recommend

I put a 20-in premade supply line from Menards in a loop from the water pump discharge to one side of the accumulator. The water line that used to connect to the discharge side of the water pump is now connected to the other side of the accumulator. I mounted the accumulator vertically on a strip of plywood that I installed across the plywood sides of our water heater area. Our water system is under the couch on the inside of our Jayco Flight camper. I left the accumulator factory pressure of 10 lb alone for now and tested the system after install. I already had the flexible reinforced lines on both sides of the pump, but this accumulator really did the trick. The pump and PEX lines are now unbelievably quiet compared to the hammering that was transmitting through the lines before the accumulator installation.

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.

We were pleased with it after the seller paid for a part that was damaged when we received Pump.

This tank coupled with a new water pump (no special pump, normal on/off shurflo without variable speed) accomplished several things. Water pump cycling markedly reduced, water flow surging with low faucet flow (pump cycling on and off repeatedly) basically eliminated, smooth flow all the time. Sounds levels cut way down, not sure though how much of that is from adding this tank and how much was a combination of new pump and rerouting the water lines to eliminate right angle fittings at the pump.

Definitely helps with pump cycling!

It paired well with Pentair shurflo pump on my Coachmen Galleria (Sprinter Camper Van). It really quieted down the entire system, and kept my hard pex water lines from slapping inside of the walls of my shower. Before adding water into the accumulator I set the pressure to 38psi, a few psi below the pump cutoff pressure.

Fungerar som den ska 👍

Nice price

Easy to fit, very light, fixed the pump pulsing when tap turned on. Perfect!

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

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