## At a glance

- The manufacturer describes an internal bladder that separates gas and water and an adjustable pressure design.
- The listing says the tank is intended to reduce water pulses and stabilize flow with compatible pumps.
- A rubber base is described as helping reduce noise, while the compact dimensions are aimed at tight installation spaces.

## Pros

- The 0.75 L tank and stated 1/2-inch MNPT port provide concrete sizing and connection details for planning an installation.
- The listing claims two quick-connect fittings and four adjustable metal clamps are supplied, potentially reducing the need to source those components separately.

## Before you buy

- Listing details are inconsistent about the pre-charge: the specifications state 10 PSI, while installation guidance says to set tank air pressure 3 PSI below the pump switch pressure. The main product dimensions are approximate and differ from the separately listed package dimensions. Confirm the correct charge setting for the pump and available installation space before fitting.

## A good fit for

- RV or camper owners seeking an accumulator to smooth water flow in a pump-based plumbing system.
- Buyers whose plumbing uses a compatible 1/2-inch MNPT connection and who need a compact tank.

## Less suited to

- Buyers who need a standalone water pump rather than an accumulator tank.
- Installations that require a different port size or a confirmed pump-specific pressure setting not established by the listing.

## Customer feedback

Aggregate ratings skew positive, with many five-star ratings and a smaller share of three-star ratings. This is a limited snapshot and does not show what customers liked or disliked. For buyers considering the listed 0.75 L tank, the ratings alone do not establish installation fit, pressure-setting suitability or performance with a particular pump.

## Frequently asked questions

### What is the tank capacity and maximum pressure?
The listing specifies a 0.75 L volume and a maximum pressure of 125 PSI.
### What connection does it use?
The stated port is 1/2-inch MNPT. Confirm that it matches your plumbing and fittings before installation.
### What is the specified pre-charge pressure?
The listing gives 10 PSI, but its installation guidance also says to set air pressure 3 PSI below the pump switch pressure. Because these instructions differ, verify the appropriate setting for your pump.
### What components does the listing say are included?
The package-list text claims one tank, two 1/2-inch MNPT quick-connect fittings and four adjustable metal clamps. Check the selected listing to confirm the kit.
