Description

The PENTAIR SHURFLO 182-200 Pre-Pressurized Accumulator Tank is designed to improve the performance of freshwater pressure systems by storing water under pressure and reducing fluctuations in flow. The built-in diaphragm and 30 PSI factory pre-charge help maintain consistent water delivery while supporting system demand. Engineered to reduce pump cycling, pressure spikes, and water pulsation, this accumulator tank helps extend the life of pressure switch- controlled pumps while reducing operating noise. It also helps conserve battery power by minimizing frequent pump starts and stops, making it suitable for mobile and off-grid applications. Compatible with pressure requirements from 20 PSI to 125 PSI, the accumulator tank is ideal for RV, marine, industrial, and utility water systems. Its durable construction, compact design, and versatile installation options make it an effective solution for improving water system performance and reliability.

works great to remove water hammer.
Removed the water hammer I was getting from my oxygenatics shower head. It also makes it so I don't have to run the pump all the time since it holds alot of water and pressure in the system. I can even flush the toilet without needing the pump on. This was completely worth installing. I warn you though it's tough to install without leaks since pipes and fittings from home depot are just barely off and they leak so get the fittings you can buy from camco they match up and don't leak. ... show more

As expected
Good product, i got it as a replacement for and rv. Easy to install and instructions are short and clear

Quality item.
Works very well with the shurflo pump on my rv. Before I installed it the pump would come on for a couple seconds every 30 seconds or so and hit hard on the last pump (copper plumbing is not elastic). Now that has stopped and the pump doesn't come on at all until a faucet is opened. The system holds pressure indefinitely and never did before. It was necessary to set the pressure right - a little below the shut off pressure of the pump. It came depressurized. If the pressure is set too high it's just like it wasn't there. A good improvement to my water system. As others have said, it does not come with hose barbs - rather shurflo's bridge connector between it and the pump. My pump had hose barbs on both ends, so I removed the output one and put it on the tank. Included in the package was the connector that goes between pump and tank. These have wings on them and get turned hand tight and seal very well. To make the system more compact and fit better into my space I ordered a right angle hose barb for the pump input. Shurflo has a number of adapters to choose from. ... show more

Works as designed
The accumulator does what it is designed to do. It has a sturdy housing and decent mounting base. It comes with one swivel fitting but I would prefer it came with two as it does has two water line connections. I bought the accumulator as an Amazon Warehouse deal and it's hit and miss with them as to whether the item condition is described properly. The first one "like new" was missing the fitting, instructions, and box, while on the second try I got a "like new" that was complete. ... show more

Really helps quiet and even out Shurflo pump
I've had a small Shurflo AC pump in my shallow tile well for years. I simply hung the pump on paracord into the well and could never figure out how to attach one of those round 1-gallon accumulator tanks to the pump without putting some sort of wooden platform into the well, which would not be food grade...stainless steel seemed expensive, and how to put stainless legs on it in the well or suspend the platform ? ... I saw this little accumulator tank recently and was chopping vegetables on my poly cutting board and thought 'hey I could mount both of those on a cutting board like this and hang the both of them into the well together !'. It is small and light enough, can work horizontally or vertically, the same as the pump, and I wouldn't have to find any special couplings because it's all the same threads as the pump I already had working. I bought a Farberware 12 by 18 inch 1/4 inch thick poly cutting board on Amazon for 10 bucks, and attached the coupled pump and tank to board by marking mounting holes, drilling like a wood board, and 'sewing' the pump and tank on to the board with skinny paracord (which is incredibly strong, abrasion-resistant, doesn't hold moisture or mold, wouldn't potentially vibrate loose like stainless nuts and bolts, and was already on hand for hanging the whole deal into well.) It is small but has really made a difference in how my pump runs! It's quiet now (maybe too quiet -- I left water running and forgot about it) and there's no more bursts of water when I turn on the tap or cycling of the pump when I reduce the pressure of the pump to avoid bursts of water. Wish I had figured out how to mount it in my shallow well application years ago. One criticism: When I bought this a couple months ago it was advertised as being pre-pressurized to 30 lbs; but it came completely unpressurized, which the instructions said was due to shipping regulations. It was easy enough to pressurize at the gas station with the tire attachment, but it would have been nice to know I was going to have to do that before starting to hook it up. ... show more

Perfect addition to any RV!
I was having a couple of issues with my class c rv. “Chattering” and low demand couples with pulsing at high demand, and then a couple of times, we had hot water coming from cold water faucets. Strangely enough, I tracked it down to the water heater. There is supposed to be an air gap in the water heater which acts as a buffer, or accumulator. When you bounce around like crazy on bad roads, this air gap can dissipate cause all of the symptoms. While reading up on causes and fixes, I learned that adding an accumulator such as this can fix it. I already had a Shurflo water pump, so I ordered this model. I did not need any additional parts or hose. I simply added this to the output side and put 30 psi in the accumulator. It is a godsend. Now at low demand, the pump does not constantly turn off and on. No more chattering, pulsing...nothing. I even get a couple of toilet flushes during the night without turning on the water pump! I have not used it long enough to find out if it allows for enough buffering to fix the hot water out of the cold faucet issue. I honestly think that these should come with the water pumps, but for this price, no big deal to add it later. Highly recommend! ... show more

Who knew?
I had no idea I needed this until after I installed it. Consistent pressure all the time, no more pulsating water. Even my friends commented that my water is so smooth…
