A well pump can cycle on and off while household taps continue to demand water, leaving pressure that feels uneven in the shower and weak at the kitchen sink. The right pressure tank stores water between pump cycles, while related switches, covers, fittings, and RV pumps solve narrower parts of the setup. This guide covers the capacity, connection, and operating details that matter for your home.

Meet The Standout Selections
A hose that bends sharply at an RV or residential hookup can place unnecessary force on the connection. The Camco Model 22605 redirects the hose through a 45-degree brass elbow, reducing that sharp change in direction.
Unlike the pressure tanks later in this list, this fitting solves a connection problem rather than storing water. It works well for travelers tired of seeing their intake hose kink beside a wall or pedestal.
A Few Strong Suits
- The angled path softens bends that might otherwise work against a water intake hose.
- Solid brass suits exposed hookups where a durable metal connector makes sense.
- A swiveling grip section adds handling flexibility during connection and disconnection.
- The design supports RV city-water hookups and suitable residential connections.
Points To Keep In Mind
- Confirm that both ends of your existing hose and water source match the elbow’s connection arrangement.
Quick Facts
Made For
This elbow is best for RV owners and homeowners who want a gentler hose bend at a frequently connected water source.
Consider Something Else When
Choose the Red Lion RL20A 20-Gallon Tank instead when your actual need is stored water and steadier household pressure rather than a better hose connection.
An outdoor well tank faces more than cold temperatures. Sun, rain, snow, and wind can work on exposed surfaces over time, while an uninsulated tank may need added protection during harsh winter weather. The Cold Snap cover combines insulation with a weather-resistant outer shell.
Its three-way, 28-by-64-inch design is aimed at a specific vertical tank rather than every well installation. For a basement or mechanical room with similar exposed equipment, it can serve as a seasonal cover without taking up floor space inside the home.
Where It Excels
- Insulation adds a buffer between winter air and an outdoor pressure tank.
- The outer shell resists ultraviolet exposure, helping limit fading and surface deterioration.
- Weather-resistant construction suits exposure to rain, snow, wind, and ice.
- The vertical shape wraps around a round tank rather than covering an entire mechanical area.
Things To Consider
- The listed dimensions need to match your tank’s diameter and height closely.
- It is a tank cover, not a replacement pressure vessel or pressure switch.

Another Choice May Suit
The Amtrol WX-202XL Pressure Tank is the better choice for someone replacing the tank itself instead of insulating an existing one.
The Merrill MPS3050 does something different from a pressure tank: it tells the well pump when to start and stop. Its adjustable pressure range begins at a 30 PSI cut-in point and reaches a 50 PSI cut-off point, with the differential controlling the gap between them.
This makes it relevant to a repair visit rather than a capacity upgrade. Homes with submersible, jet, or reciprocating well pumps may find its broad application useful, while the Red Lion tanks are the better starting point for adding stored water.
Real Benefits
- Adjustable cut-in and cut-off settings give you control over the operating pressure window.
- Large contacts suit pumps up to 2 HP on 115-volt, single-phase power.
- Open-on-rising-pressure operation lets the switch activate the pump as system pressure climbs.
- The 1/4-inch female NPT connection suits many standard well-control assemblies.
Worth Noting
- A pressure switch cannot add stored water to the system, so it does not replace a pressure tank.
- The NEMA 1 enclosure is best suited to a dry, protected installation area.
- Verify the existing switch’s thread size, voltage, pump horsepower, and pressure range before replacement.
Built With In Mind
This switch is designed for DIY maintenance and service technicians replacing a standard well-pump pressure control.
Look Elsewhere When
Choose the Red Lion RL34A 34-Gallon Tank instead when your goal is a larger stored-water reserve rather than replacement pump controls.
The Amtrol WX-202XL brings a generous 26-gallon tank to a residential well system that needs more stored water than a compact model. Its factory air precharge is 38 PSI, creating the initial air cushion that supports steady pressure as the diaphragm expands and contracts.
The 1-inch NPT connection makes thread compatibility your first practical check. Compared with the Red Lion RL14A 14-Gallon Tank, this model offers a larger reservoir, though the additional size needs room in the mechanical area.
Strengths Worth Knowing
- The 26-gallon volume gives the pump a larger stored reserve between operating cycles.
- A factory precharge of 38 PSI supplies a defined starting air pressure.
- The steel shell supports the tank’s pressure-vessel construction.
- A heavy-duty butyl diaphragm separates the water from the air cushion.
Trade Offs
- The larger tank requires more physical room than the Red Lion RL14A.
- Its 1-inch NPT connection must match the existing tank tee and piping arrangement.

Reach For A Different Pick When
The Red Lion RL14A 14-Gallon Tank is a better fit when floor space is limited and a smaller water reserve is enough.
The Red Lion RL34A is built around a straightforward idea: store more water for the moments when household demand outpaces the well pump. Its 34-gallon volume is the largest listed among these tanks, giving a home with several fixtures more of a reserve between pump starts.
The steel shell, stainless steel water connection, butyl rubber diaphragm, and propylene liner form a practical internal arrangement for a vertical well-pressure tank. You still need to confirm the physical footprint and connection details before ordering, but the capacity gives this model a clear role in larger residential setups.
Why It Works Well
- The 34-gallon capacity is well suited to households needing a substantial stored-water reserve.
- Vertical construction fits the upright format commonly used with well systems.
- A stainless steel water connection provides a durable metal interface.
- The butyl rubber diaphragm supports repeated expansion and contraction during tank operation.
- A propylene liner separates the water side from the tank shell.
Where It May Fall Short
- Its greater capacity requires more installation space than the 14- or 20-gallon Red Lion models.
- Large capacity alone does not guarantee fewer short pressure drops in every household.
Built With In Mind
This model best serves a larger home that needs a generous pressure reserve and has room for a vertical tank.
Where A Sibling Pick Shines
The Red Lion RL14A 14-Gallon Tank is the better fit for a compact mechanical area where space matters more than reserve capacity.
A smaller mechanical room can make tank capacity one of the most practical decisions. The Red Lion RL14A holds 14 gallons and uses a vertical layout, offering a compact tank option for a residential well where every bit of floor space matters.
Its steel shell, stainless steel connection, butyl rubber diaphragm, and propylene liner follow the same basic material approach as the larger RL20A and RL34A. The honest difference is capacity: this model gives you less stored water, so it works best where household demand is modest or the surrounding plumbing layout is tight.
The Case For It
- The 14-gallon capacity fits more easily into a compact installation area.
- Vertical tank construction suits a standard upright utility-space layout.
- The stainless steel connection offers a durable water-side fitting.
- The butyl diaphragm and propylene liner support the tank’s water-and-air separation.
Less-Strong Areas
- It stores less water than the Red Lion RL20A and RL34A models.
- A smaller reserve may be less useful in a home that runs several fixtures at once.

Who Will Love This
This tank suits homeowners with limited installation space and relatively modest household water demand.
Swap It Out When
The Red Lion RL20A 20-Gallon Tank makes more sense when you have room for a moderate reserve and want more stored water.
The Red Lion RL20A sits between the RL14A and RL34A in capacity, which makes it the easier middle-ground tank for many residential installations. A 20-gallon volume can support a useful stored-water reserve without reaching the footprint of the 34-gallon model.
The vertical steel tank uses a 304 stainless steel connection, a variable-geometry butyl rubber diaphragm, and a propylene liner. Those components serve the same basic function as the smaller RL14A, while the added capacity gives households a little more breathing room between pump starts.
Strong Points
- The 20-gallon capacity offers a balanced choice between compact size and reserve volume.
- A 304 stainless steel connection provides a strong metal water-side component.
- The variable-geometry butyl diaphragm supports repeated operating cycles.
- Vertical construction suits an upright installation area.
Possible Compromises
- It needs more space than the Red Lion RL14A because of its larger capacity.
- It offers less reserve than the Red Lion RL34A for households with heavier peak demand.
- Confirm the tank connection and available clearance before installation.
The Right Fit
This tank is a sensible middle ground for a residential well with normal household demand and moderate installation space.
Not Your Match When
The Red Lion RL34A 34-Gallon Tank suits a larger home that prioritizes reserve capacity over a smaller mechanical-room footprint.
An RV water pump has a different job from a household well-pressure tank: it moves fresh water from a vehicle or boat tank into the plumbing system. The hzhdven model delivers a listed 7 gallons per minute at up to 70 PSI, useful for a compact galley, bathroom, or outdoor rinse connection.
Its five-chamber diaphragm design provides several water passages within the pump body, while self-priming behavior helps the unit draw from its supply tank. The included pressure switch and strainer make this a more complete RV pump assembly than the Camco elbow, though its 12-volt DC power makes it primarily suitable for mobile systems.
Where It Helps
- The 7 GPM flow rate supports useful fresh-water output for RV fixtures.
- A listed 70 PSI maximum gives the pressure switch a defined operating ceiling.
- Five diaphragm chambers provide multiple passages for water movement.
- Self-priming operation suits pumping from an onboard fresh-water tank.
- The pressure switch and strainer are included as part of the pump setup.
Details To Watch
- The 12-volt DC power supply requires suitable vehicle or marine electrical connections.
- It does not store well water and is not a replacement for a residential pressure tank.
- Confirm available space, mounting position, and plumbing connections before installation.
Technical Highlights
Made For
This pump suits RV, yacht, caravan, and camper owners who need a 12-volt fresh-water system for a compact plumbing setup.
Skip It When
The Red Lion RL20A 20-Gallon Tank is the better choice for a stationary residential well that needs stored water and household pressure support.
Matching Well Pressure Equipment to Your Setup
Start with the job each component performs
A pressure tank stores water, while a pressure switch controls the pump. The hzhdven RV pump moves fresh water from an onboard tank, the Cold Snap cover insulates an exposed pressure tank, and the Camco elbow improves a hose connection. Treating these parts as interchangeable can leave you with a component that does not solve the actual issue.
Match tank capacity to available space and demand
A diaphragm tank uses an air cushion and flexible bladder to hold pressurized water. The 14-gallon Red Lion RL14A takes less room than the 34-gallon RL34A, while the 20-gallon RL20A offers a middle-ground reserve. For most suburban homes, the Amtrol WX-202XL’s 26 gallons provides another useful middle option.
Check the connection and operating details
NPT means national pipe thread, a tapered pipe connection used by the Amtrol and Merrill components. Match the thread size before ordering, and check the switch’s voltage and pump rating against your existing well equipment. A pressure switch set at 30 PSI cut-in and 50 PSI cut-off must also fit the rest of your system’s pressure plan.
Consider precharge carefully
Factory precharge is the air pressure placed in a tank before it enters service. The Amtrol model carries a listed 38 PSI precharge, while the Red Lion tanks arrive precharged for well systems. Your installation should account for the tank’s air setting so it supports the pressure range established by the switch.
Two Details That Shape Your Decision
Mistakes Worth Dodging
Selecting by gallon capacity alone misses connection and space requirements. Measure the installation area, identify the existing thread size, and confirm the component belongs in the water or power path you intend to address.
The Upgrade Payoff
A larger tank adds stored water, while a more capable RV pump adds flow for a mobile system. The added capacity or output matters only when your available space, electrical system, and plumbing arrangement can support it.
Frequently Asked Questions
Are all well pressure tanks interchangeable?
No, because connection size, tank volume, precharge, and system requirements must align with your existing plumbing. Match the thread size and confirm the tank’s operating limits before installation.
What does factory-precharged mean for a pressure tank?
It means the tank’s air cushion starts at a specified pressure before service. The Amtrol WX-202XL has a listed factory precharge of 38 PSI, which forms part of the system’s pressure balance.
Is a pressure switch the same as a pressure tank?
No, a switch controls when the pump operates, while a tank stores pressurized water. The Merrill MPS3050 supplies pump controls, and the Red Lion and Amtrol models supply water reserves.
Does a larger pressure tank automatically improve every home?
No, a larger tank can provide a greater reserve, but connection compatibility, installation space, and demand still matter. Choose capacity based on your system rather than size alone.
Can a 12-volt RV pump replace a household well pump?
Usually not, because the hzhdven model is designed for an RV or marine fresh-water system. A residential well installation requires equipment matched to its well pump, power supply, pressure range, and plumbing connections.
Closing Remarks
The right choice depends on the role your system needs: stored water, pump control, weather insulation, a gentler hose bend, or mobile fresh-water flow. Red Lion RL20A 20-Gallon Tank offers the most balanced residential capacity here, while the Amtrol WX-202XL provides a larger alternative. Match the connection and installation space before making the final call.
