It has a drawdown of 8-10oz.. On my RV trailer. **Q: what is the maximum pressure?** A: All are guessing at operating function. 1st item is a accurate guage to measure/record pump on and off pressures. After installing accumulator, fill system up and flush air from lines. Turn on pump and recheck/record on/off pressures. Set pressure on new accumulator to 2 psi below the turn on of the pump. Check 2 or 3 times by open faucets. 2 psi below the pump cut in pressure. This is the correct procedure setting for any pressure accumulator with a bladder. **Q: Will this work with a seaflow 12v 4.3lpm water pump?** A: My boat is plumbed with braided hose. My favorite fresh water piping is PEX, but I am not planning to change at this point. The pump is a 4.5GPM 12V serving a total of four sink fixtures plus two heads and a shower. Hope this helps. **Q: what is the size of this tank and what material it's made of?** A: The tank capacity is 21oz, or 1/6 gal. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Really helps quiet and even out Shurflo pump *by on Reviewed in the United States May 21, 2018* 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. ### ⭐⭐⭐⭐⭐ Quality item. *by on Reviewed in the United States September 26, 2022* 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. ### ⭐⭐⭐⭐ Quiets pump *by on Reviewed in the United States November 7, 2024* This is easy to install and quiets pump down considerably. It gives you a few seconds between pump cycles which doesn't sound like much but consider if you cut 2 cycles out every few seconds how many less cycles the pump has to do. The reason for 4 stars is because I was hoping for a little more time between cycles. ## Frequently Bought Together - SHURflo 182-200 Pre-Pressurized Accumulator Tank,Black, 9.1" x 4.8" x 3.8" - SHURFLO (255-313) 1/2" Twist-On Pipe Strainer - SHURFLO 4008-101-A65 New 3.0 GPM RV Water Pump Revolution, 12V --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/3930806-pentair-shurflo-182-200-pre-pressurized-accumulator-tank-125-psi](https://www.desertcart.co.za/products/3930806-pentair-shurflo-182-200-pre-pressurized-accumulator-tank-125-psi) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-02*
