## Description

Plastic construction and compact 9.65 x 4.49 x 4.92-inch dimensions make the Gidrox RVDHP4-H practical for RV, boat, and mobile water setups. It runs on 110V AC and delivers up to 5 GPM. A built-in pressure switch starts and stops the pump automatically as water is needed.

## Getting the most from it
Use this diaphragm pump to supply fresh water for an RV shower, rinse station, or other setup that draws from a tank. Its self-priming capability reaches up to 10 feet, which helps when the water source sits below the pump, such as a tank mounted under a vehicle chassis. The 5 GPM flow rate also suits tasks such as filling a tank or watering a garden.

The pressure switch is factory set to 55 PSI and adjusts from 30 to 80 PSI. That range lets you tailor the pressure to the task: a gentler setting for watering or a stronger rinse for cleanup. The pump operates from a 110V AC outlet, making it a fit for installations with access to mains power. Compared with a 12V pump intended for portable or off-grid use, this 110V model is aimed at setups where an AC connection is available for ongoing or higher-demand water use.

Included fittings support different connection styles. The set includes a 1/2-inch male threaded elbow, a 1/2-inch-to-3/4-inch metal garden hose adapter, barbed elbows and fittings, and a 50-mesh stainless steel filter screen. Match the connection to your hose or plumbing layout when installing the pump.

## Why it’s worth it
The combination of automatic pressure control and adjustable settings gives the RVDHP4-H a useful role in both everyday water delivery and task-specific rinsing. Rather than choosing a pump with a fixed pressure setting, you can adjust output to suit the job, while the pressure switch manages start and stop operation as water is drawn. Its included adapters and fittings also provide several connection options for RV, camper, boat, and mobile service setups.

For a practical example, an RV owner can draw water from a lower-mounted tank and set the pressure for a shower or cleanup. The same pump can serve a food truck or marine setup with an available 110V outlet. A three-year warranty and U.S.-based customer support are also provided.

## Questions before you buy
Can it draw water from a tank below the pump? Yes. The pump is self-priming up to 10 feet, making it suitable for drawing from a lower water source.

Can the pressure be adjusted for different tasks? Yes. Its pressure switch is adjustable from 30 to 80 PSI and comes factory set to 55 PSI, so you can select a setting for watering, showering, or rinsing.

What power connection does it use? It operates on 110V AC. Choose it for a setup with access to an AC outlet, a 12V pump is the alternative described for portable or off-grid use.

## Is it worth it?
For RV and marine owners, or mobile operators with an AC power source, the Gidrox RVDHP4-H combines self-priming from a lower tank, adjustable pressure, and automatic start-stop control in one compact pump. Those features make it a practical choice for fresh-water delivery when the same setup needs to handle showers, rinsing, or tank filling.
