Installing a yard hydrant is a great way to have an outdoor water source for gardening, washing cars, pets, and more. With the right planning and preparation, installing a yard hydrant can be a straightforward DIY project. Here are some key instructions and tips to ensure proper yard hydrant installation.

Choosing the Right Location

Choosing the optimal location is one of the most important steps when installing a yard hydrant. Here are some key factors to consider:

Accessibility – Pick a spot that is easy to access and utilize. Avoid locations that would get blocked by vehicles, structures, vegetation etc.
Hose Reach – Consider the activities the water will be used for and pick a location central to those needs that maximizes hose length reach.
Drainage – Choose a spot where water drainage will flow away from any structures or low areas to prevent flooding issues.
Utilities – Avoid installing the hydrant over other buried utilities like electrical, gas or sewer lines. Call 811 before digging to identify.
Comfort – Select a location that is comfortable to access in all weather conditions. Make sure it is a clear path without obstructions.
Visibility – Choose a spot with good visibility to monitor leaks or other issues. Avoid hiding the hydrant behind structures or landscaping.
Ground – Pick an area with stable, compacted soil for digging the required hole and setting the base. Avoid loose soils.
Yard Layout – Find a location that doesn’t disrupt landscaping or yard designs and allows the hydrant to blend into the space.
Freeze Protection – In cold climates, avoid installing on the north side of structures where limited sun exposure could lead to freezing issues.
Local Codes – Verify setback requirements from property lines, structures, or septic systems according to local codes.

Thoroughly evaluating the site conditions and needs will ensure the best location is chosen for trouble-free hydrant operation.

Choosing the Right Hydrant

There are many types of yard hydrants on the market that range widely in terms of features, materials and cost. Key factors to consider when selecting a model include:

Below Ground or Above Ground – Below ground models provide freeze protection while above ground models are easier to access and service. Choose based on climate and winter temperatures.
Materials – Brass, stainless steel and thermoplastic are common options. Consider material grade, longevity and cost. Avoid galvanized steel or iron.
Style – Standard or floppy spout, potable or non-potable usage, straight or angled neck are some of the configuration options.
Depth – Pick a model that can be installed at the required depth based on frost line and burial requirements in your local area.
Flow Rate and Pressure – Choose a hydrant that meets expected water volume and pressure needs based on planned usage.
Shutoff Valve – Models with interior or exterior shutoff valves allow the water to be turned off for maintenance.
Drainage – Hydrants with weep holes or internal drainage provide improved water drainage.
Accessories – Some models include handy accessories like yard swivels, hooks, hose reels etc.

Selecting the right hydrant model upfront makes the rest of the installation smooth and ensures optimal ongoing performance and longevity of the hydrant. Check local plumbing codes for any special requirements when picking a yard hydrant.

Gathering the Required Materials

In addition to the yard hydrant itself, some other key materials and tools needed for installation include:

Main Water Line Materials – Copper, PEX or PVC piping, fittings, valve and other supplies to connect the hydrant to the main water line.
Drainage Gravel – Gravel and crushed stone to surround the base of the hydrant below ground to facilitate drainage.
Concrete Mix – For anchoring the bottom section of the hydrant in place below ground if required.
Soil and Backfill – Extra soil may be needed for backfilling the hole during the underground installation stages.
Shutoff Valves – Gate or ball valves for the main supply line, and at the hydrant inlet connection.
Hose Bib and Connector – Items to connect a hose to the above ground hydrant spout.
Trenching Tools – Shovels, breaker bar, saw for digging the required trenches to access and connect the main supply line and drainage.
General Tools – Wrenches, pipe cutter, level, hacksaw, tape measure, clamps, sandpaper, sealant etc.

Having all required materials and tools on hand will make the installation process smooth and efficient from start to finish.

Step-by-Step Installation

Once the site is selected, the model purchased, and materials acquired, the hands-on installation process can begin. Here are the key steps:

Trenching

Mark the locations for the supply and drainage trenches running from the main line to the planned hydrant location.
Dig trenches at the required depth and width following local plumbing codes to allow access to the supply line and installation of drainage gravel bedding.
If a gate or ball valve will be used, dig a hole at the supply line to install it to control main line water access.

Supply Line Connection

Shut off the water supply at the main line and open downstream faucets to drain the line.
Cut into the supply line at the marked connection point using the proper tubing cutter.
Install the gate or ball valve if used.
Run new supply line tubing from the connection point to the hydrant location and cut to proper length using tubing cutter.
Use required fittings to connect the supply stub to the inlet port of the yard hydrant, securing all connections.

Hydrant Installation

Attach the upper barrel section to the lower casing section per manufacturer instructions.
Place a gravel drainage bed of 4-6 inches in the buried hole for the hydrant base section to sit on.
Lower the assembled hydrant into the hole, positioning it vertically with the spout end facing the desired direction.
Surround with more gravel to provide drainage up to ground level around the hydrant base.
Pour concrete mix if using and allow to cure as per manufacturer directions to stabilize the hydrant base section.
Backfill the remaining hole with soil, packing firmly every 6 inches. Slope soil away from hydrant to direct surface runoff.
Connect supply line to the inlet port and secure firmly. Turn on main supply and check for leaks. Fix any found.
Attach hose bib and/or other accessories to the above ground hydrant spout as needed.

Drainage

Lay perforated drainage pipe in the drainage trench running away from the hydrant location, sloping downwards.
Fill the trench back up with gravel, packing firmly.
Direct the drainage endpoint away from any structures to disperse water runoff.

Finishing Touches

Mark the hydrant location to protect it from being obstructed.
Flush and disinfect the hydrant per manufacturer directions before first use.
Test functionality and check for leaks under operating pressure before completing work.
Winterize in cold climates by shutting off and draining the hydrant before first freeze each year.

Thoroughly following the manufacturer instructions combined with proper installation techniques will ensure a secure and lasting yard hydrant setup. Ongoing maintenance like lubricating seals, checking drainage and checking for leaks periodically will keep the hydrant functioning properly for many years.

Common Mistakes to Avoid

It is important to avoid some common missteps both in planning and executing the installation to prevent problems down the road:

Not calling 811 – Failing to call 811 before digging risks hitting buried utility lines during trenching. This can harm workers, disrupt utilities and require expensive repairs.
Incorrect depth – Burying the hydrant at the wrong depth risks frost damage in cold climates if not deep enough or submergence if too deep. Follow guidelines.
Improper drainage – Lack of proper gravel backfill or downward sloped drainage can lead to water collecting and freezing around the hydrant base.
Not checking for leaks – Failing to thoroughly test for leaks under operating pressure can lead to issues after burial like water waste, flooding, erosion and hydrant damage over time.
Wrong materials – Using subpar tubing, fixtures, or components risks premature failure. Stick to quality manufacturers’ specifications.
Ignoring codes – Disregarding plumbing codes for things like hydrant type allowed, minimum distances or burial depth results in non-compliant installs.
No freeze protection – In cold climates, failure to winterize a frost-prone hydrant leads to internal damage over winter. Shut off and drain the hydrant properly each fall.
No obstruction prevention – Neglecting to protect hydrant location leads to blocked access behind structures, under decks or behind plantings.
Poor supply valve – Skipping a shutoff valve on the supply line makes isolating and servicing the hydrant difficult down the road. Always include one.

Double checking details at each step, following all codes and manufacturer instructions carefully, and testing thoroughly will avoid most common missteps that lead to problems.

Freeze Protection Tips

In climates where sub-freezing temperatures occur, yard hydrants need special protection to avoid frost damage. Here are some key freeze protection strategies:

Drain Completely – Fully draining the hydrant of all remaining water before winter is crucial to preventing internal freezing damage.
Below Ground Model – Burying the hydrant below the local frost line depth keeps the valves and workings in warmer earth all winter.
Insulate Underground – Wrapping the below ground barrel section with insulation provides added protection on severe winters.
Remove Hose – Detaching and storing the hose over winter prevents trapped water freezing inside the hose and hydrant.
Store Spout Down – Having the hydrant spout pointed downwards allows all remaining water to fully drain out if any is left behind accidentally.
Heat Tape – In extreme climates, heating tape around above ground components keeps them safely above freezing if needed.
Insulate Spout – Foam spout insulation caps are available to provide protection on above ground freeze-prone models.
Wood Box – A wood box wrapped around above ground portions can insulate against frost. Allow ventilation to prevent mold.
South Exposure – If installing an above ground hydrant, placing it on a structure’s south facing side gets more sun exposure for natural warmth.

Preventing internal freezing damage ensures yard hydrants remain functional for their full lifetime. Be diligent before the first deep freeze each winter season.

Troubleshooting Common Problems

If issues arise, there are some quick troubleshooting steps to attempt before calling a professional:

No water flow

Check if main supply line valve is on
Inspect for kinked supply line
Remove spout and clear obstructions
Assess for frozen internal components
