How to Replace a Solenoid Valve in Your Elkay ezH2O Water Fountain

Your Elkay ezH2O water fountain has been faithfully serving your facility for months or years, but suddenly it’s acting up. Maybe the water won’t dispense at all, or perhaps it won’t stop flowing. Before you call for expensive professional repairs, you might be dealing with a faulty solenoid valve—one of the most common issues with commercial water fountains.

The solenoid valve is essentially the gatekeeper of your water fountain’s dispensing system. When someone presses the activation button, an electrical signal tells the solenoid valve to open, allowing water to flow. When they release the button, the valve closes, stopping the flow. This simple but crucial component can fail over time due to mineral buildup, electrical issues, or general wear and tear.

Replacing a solenoid valve on an Elkay ezH2O might sound intimidating, but it’s actually a manageable repair for most maintenance professionals. With the right tools, a replacement part, and some patience, you can have your water fountain back in working order without the hefty service call fees. This guide will walk you through everything you need to know about Elkay ezH2O repair, from identifying the problem to completing the solenoid valve replacement successfully.

Understanding Your Elkay ezH2O Water Fountain System

The Elkay ezH2O series has become a standard in schools, offices, and public facilities across the country, and for good reason. These units combine traditional drinking fountain functionality with bottle-filling capabilities, making them incredibly versatile for high-traffic environments. The sleek design and reliable performance have made them a go-to choice for facility managers everywhere.

At its core, your Elkay ezH2O operates on a relatively straightforward system. Cold water enters the unit through your building’s plumbing, passes through a refrigeration system to achieve the desired temperature, and then waits behind the solenoid valve until someone activates the dispensing mechanism. The bottle-filling station typically has its own solenoid valve, separate from the traditional drinking fountain spout.

The solenoid valve itself is an electromechanical device about the size of your fist. It contains a coil that creates a magnetic field when energized, which moves a plunger to open or close the water pathway. This design allows for precise control over water flow and immediate shut-off when the activation button is released. When this component fails, it can cause a range of issues that affect the fountain’s basic functionality.

Understanding this system helps explain why solenoid valve problems are so disruptive. Without a properly functioning valve, you lose the ability to control when and how water flows from your fountain—pretty much defeating the entire purpose of the unit.

Identifying a Faulty Solenoid Valve

Water fountain troubleshooting starts with recognizing the symptoms of a failing solenoid valve. The most obvious sign is when pressing the activation button produces no water flow at all. You might hear the familiar hum of the refrigeration system running, but no water emerges from either the drinking spout or the bottle-filling nozzle.

On the flip side, a valve that won’t close creates the opposite problem—continuous water flow that won’t stop regardless of whether anyone is using the fountain. This not only wastes water but can create flooding issues if left unchecked. Some facilities have discovered their water bills skyrocketing due to a single malfunctioning solenoid valve.

Listen carefully to your fountain during normal operation. A healthy solenoid valve makes a subtle clicking sound when it opens and closes. If you’re hearing unusual buzzing, grinding, or clicking sounds that seem excessive, the valve mechanism may be struggling due to mineral buildup or mechanical wear.

Many newer Elkay ezH2O models include diagnostic displays that can help pinpoint problems. Error codes related to water flow or valve operation often point directly to solenoid valve issues. Check your unit’s manual for specific error code meanings, as these can save you significant troubleshooting time.

To confirm a solenoid valve problem, try this simple test: with the power connected and water supply on, listen closely while pressing the activation button. You should hear a distinct click as the valve opens, followed by immediate water flow. When you release the button, you should hear another click as the valve closes and water stops immediately. Any deviation from this pattern—delayed response, no clicking sounds, or inconsistent water flow—suggests valve problems.

Tools and Materials You’ll Need

Before starting your solenoid valve replacement, gather all necessary tools and materials. Having everything on hand prevents mid-project trips to the supply house and ensures you can complete the job efficiently.

Your tool kit should include both Phillips head and flathead screwdrivers in various sizes, as Elkay uses different screw types throughout their units. A set of pliers will help with disconnecting water lines and electrical connections, while a wrench set ensures you can properly tighten threaded connections.

A multimeter is invaluable for testing electrical continuity and voltage, helping you verify that the problem is indeed the solenoid valve rather than a power supply issue. A voltage tester provides an extra safety measure when working around electrical components.

For materials, you’ll need a replacement solenoid valve specifically compatible with your Elkay ezH2O model. These valves aren’t universal, so double-check your fountain’s model number and existing valve specifications before ordering. Van Marcke Plumbing Supply stocks genuine Elkay replacement parts, ensuring proper fit and reliable performance.

Don’t forget Teflon tape for sealing threaded connections—this prevents leaks that could cause water damage or reduce system pressure. Keep a small container handy for catching water spillage during disconnection, and have cleaning supplies ready to address any mess created during the repair process.

Step-by-Step Solenoid Valve Replacement Guide

Safety comes first in any plumbing repair. Start by shutting off the water supply to your fountain—this is usually accomplished with a shutoff valve located beneath the unit or along the supply line. Next, disconnect electrical power by unplugging the unit or switching off the dedicated circuit breaker. Never attempt this repair with power connected, as you’ll be working around both water and electrical components.

Accessing the Solenoid Valve

Most Elkay ezH2O units require removing side or rear access panels to reach internal components. These panels are typically held in place with Phillips head screws. Keep track of screw locations, as some may be different lengths for different mounting points.

Once inside, locate the solenoid valve assembly. In bottle-filling stations, you’ll often find it mounted near the dispensing nozzle area. Traditional drinking fountains typically house the valve closer to the main water inlet. The valve will have both water lines and electrical connections attached—this helps distinguish it from other components like temperature sensors or flow meters.

Removing the Old Valve

Before disconnecting anything, take a photo of the electrical connections with your phone. This serves as a reference for proper reconnection later. Electrical connections on solenoid valves are usually simple—two wires that connect to terminal screws or plug connectors.

Disconnect the electrical connections first, then turn your attention to the water lines. Have your container ready, as some residual water will drain from the lines. Water line connections are typically compression fittings or threaded connections that can be removed with pliers or wrenches.

As you remove water lines, note their positions. The inlet and outlet sides of the valve must be connected correctly, or your fountain won’t function properly. Many valves have arrows indicating flow direction—make note of this orientation.

Installing the New Valve

Apply Teflon tape to any threaded connections on your new solenoid valve. Wrap the tape clockwise around the threads—this prevents it from unwrapping as you tighten the connections. Two to three wraps is usually sufficient for most plumbing applications.

Connect the water lines to your new valve, ensuring inlet and outlet positions match the original configuration. Tighten connections firmly but don’t over-tighten, as this can damage threads or compression fittings.

Reconnect the electrical wires according to your reference photo. Most solenoid valves aren’t polarity-sensitive for AC power, but double-check your specific model’s documentation to be sure.

Testing Your Repair

With everything connected, slowly turn the water supply back on while watching for leaks around your new connections. Address any leaks immediately by tightening connections or adding additional Teflon tape as needed.

Once you’re confident there are no leaks, restore electrical power to the unit. Test the fountain’s operation by pressing the activation button—you should hear the characteristic click of the solenoid valve opening, followed by immediate water flow. Release the button and confirm that water stops flowing completely.

Test both the drinking fountain and bottle-filling functions if your unit has both. Some models use separate solenoid valves for each function, so replacing one may not address problems with the other.

Advanced Troubleshooting After Replacement

Sometimes issues persist even after installing a new solenoid valve. Leaks from water line connections usually indicate insufficient sealing or over-tightening that damaged the fitting threads. Try adding more Teflon tape or replacing damaged compression ferrules.

If the valve doesn’t operate despite proper electrical connections, verify voltage at the valve terminals using your multimeter. The valve should receive appropriate voltage (usually 110V AC) when the activation button is pressed. No voltage indicates problems with the control circuit rather than the valve itself.

Incompatible replacement valves can cause various operational problems. Valves with different pressure ratings, flow capacities, or electrical requirements may not work properly even if they physically fit the mounting location. Always verify compatibility with your specific Elkay ezH2O model before installation.

Unusual noises after replacement might indicate air in the water lines. Run the fountain for several minutes to purge air from the system. Persistent noise problems could suggest incorrectly sized replacement valves or debris in the water lines.

Preventive Maintenance for Long-Term Reliability

Regular maintenance prevents many solenoid valve failures before they occur. Clean your fountain’s external surfaces weekly and inspect internal components monthly during routine filter changes. Look for signs of mineral buildup, corrosion, or wear that might affect valve operation.

Monitor water pressure and flow rates as part of your routine maintenance schedule. Excessive pressure can damage solenoid valves over time, while insufficient pressure might cause valves to function improperly. Most Elkay ezH2O units operate optimally with water pressure between 20-80 PSI.

Replace water filters according to manufacturer recommendations—typically every six months in normal-use environments. Clogged filters increase system pressure and force solenoid valves to work harder, potentially shortening their lifespan.

Ensure adequate ventilation around your water fountain. Excessive heat can damage electrical components, including solenoid valve coils. Keep at least six inches of clearance around ventilation openings and clean dust buildup from these areas regularly.

Consider water quality in your maintenance planning. Facilities with hard water or high mineral content may need more frequent valve replacement and system cleaning. Installing water softening systems upstream of your fountains can significantly extend component life.
