Simple Trough Drainage for Faster Emptying & Cleaning

Need to empty a water trough without turning the clean-out into a bucket-by-bucket job? RELN drain plugs provide a removable closure for compatible trough drain points, allowing water to be released when cleaning, refreshing or maintaining the trough. Browse the wider RELN range when matching plugs with other RELN agricultural components.

Regular water changes become much easier when the drain point works the way it should. Compatible RELN water troughs use a drain plug to retain water during normal use while giving you a straightforward way to empty the vessel when required. If you're setting up or maintaining livestock watering equipment, RELN | Feed & Water Troughs is the natural place to compare the surrounding trough system.

Small component, important job: a missing, damaged or poorly seated plug can stop a perfectly usable trough from holding water properly. Check the trough model, drain opening plus existing fitting before choosing a replacement rather than assuming every plug is interchangeable.

What Are RELN | Drain Plugs?

RELN drain plugs are removable fittings designed to close the drain opening on compatible RELN products such as water troughs. When fitted correctly, the plug keeps water inside during normal use; removing it opens the drain point so the vessel can be emptied for cleaning, maintenance or a water change.

Depending on the compatible RELN product, a drain plug can help:

► Close the designated drain opening
► Retain water during normal trough use
► Provide convenient access for emptying
► Make routine cleaning more manageable
► Support periodic water replacement
► Replace a missing or damaged compatible plug
► Keep the original drainage function usable
► Reduce the need to manually scoop water from the trough

One specification is particularly worth checking before ordering. RELN's agricultural information identifies a 20mm drain plug as part of compatible Multi-Trough water-trough configurations, making the existing trough plus drain size important reference points when selecting a replacement.

For alternative livestock water-storage applications within the same brand family, RELN | Water Tubs provides another useful comparison.

Why Choose RELN | Drain Plugs?

It's easy to overlook a drain plug until the trough needs emptying or the existing one disappears. Keeping the correct fitting in place helps preserve a simple function that becomes especially valuable during routine livestock-water maintenance.

A compatible drain plug can help:

► Keep water contained during everyday use
► Allow controlled emptying when required
► Make trough cleaning less cumbersome
► Support replacement of worn or missing fittings
► Keep compatible RELN equipment functional
► Simplify periodic water changes
► Provide access to the lowest drainage point
► Reduce unnecessary handling of a full trough
► Support practical farm plus property maintenance

Replacing the correct small fitting can make more sense than improvising around the drain opening. Confirming compatibility also helps avoid makeshift plugs that don't seat correctly or become difficult to remove when the next clean-out comes around.

For moving equipment, feed, supplies plus other materials around a working property, Material Handling Equipment can complement the wider maintenance setup.

Common Applications

Where does a drain plug earn its keep? Usually when stored water needs to stay put today but leave quickly tomorrow.
► Livestock water troughs – retain water during normal animal access.
► Trough cleaning – release old water before scrubbing or rinsing.
► Water changes – make complete refreshes more practical.
► Farm maintenance – replace missing or damaged compatible drain fittings.
► Paddock setups – keep serviceable trough drainage available in livestock areas.
► Animal enclosures – support routine water-management tasks around penned livestock.
► Property maintenance – restore the drain function on compatible RELN equipment.
► Seasonal cleaning – empty suitable troughs before deeper maintenance.
► Relocation preparation – drain water before moving compatible equipment where appropriate.
► Routine inspections – remove, inspect plus refit the plug when checking the drain point.

The plug only controls the opening; it doesn't replace good trough maintenance. Water quality, cleanliness, animal use, algae, sediment plus surrounding conditions can all affect how often a trough needs attention.

Product Selection Guide

Start With the Trough

Found a loose plug in the shed? Don't assume it belongs to the trough just because it fits through the opening.

Before selecting a replacement, identify:

► RELN product range
► Trough model
► Existing drain location
► Drain opening size
► Original plug where available
► Product markings
► Condition of the surrounding outlet
► Intended use of the vessel

The host product is the best clue to the correct fitting. Matching the plug to the compatible RELN trough is more reliable than choosing by appearance alone.

Check the Drain Plug Size

A few millimetres can separate a useful replacement from a fitting that won't retain water.

RELN's agricultural product information specifies a 20mm drain plug with compatible Multi-Trough water-trough configurations.

Before ordering:

► Check the trough model
► Measure where appropriate
► Inspect the existing plug
► Confirm the drain opening
► Look for product identification
► Compare the required fitting

Treat the published size as a compatibility clue rather than permission to fit the plug to every 20mm opening. The complete fitting arrangement still needs to suit the product.

Inspect the Drain Opening

Sometimes the plug isn't the only part that deserves attention.

Look around the drain point for:

► Dirt
► Feed residue
► Sediment
► Damage
► Distortion
► Foreign material
► Wear
► Anything preventing proper seating

Cleaning the contact area before fitting the plug can make inspection much easier. Persistent leakage after cleaning may indicate that either the plug or surrounding fitting needs closer examination.

Suitable Hand Tools can support general property-maintenance jobs around trough installations without encouraging unnecessary force on plastic fittings.

Check the Existing Plug Before Replacing It

A leaking drain point doesn't automatically mean the plug belongs in the bin.

First inspect for:

► Incorrect seating
► Trapped debris
► Visible wear
► Cracks
► Deformation
► Damage around the opening
► An incorrect replacement already fitted

A quick inspection can separate a dirty fitting from a damaged one. Clean components carefully plus reassess the fit before deciding what needs replacing.

Empty the Trough With a Plan

Pulling the plug is easy; deciding where all that water will go deserves more thought.

Before draining:

► Consider the volume of water
► Check surrounding ground conditions
► Keep discharge away from areas where pooling creates problems
► Avoid unnecessary erosion
► Consider nearby structures
► Keep livestock movement in mind
► Follow applicable property requirements

A full trough can release a meaningful volume of water in a short period. Choose a suitable time plus discharge area before opening the drain.

Make Cleaning More Efficient

Once the water is out, use the opportunity to inspect more than the bottom of the trough.

Check:

► Internal surfaces
► Sediment accumulation
► Drain opening
► Plug condition
► Water inlet components
► Surrounding supports
► Accessible fittings
► General trough stability

Cleaning is also inspection time. Catching a worn fitting or unstable mounting early can prevent a small maintenance job from becoming a larger interruption later.

For broader equipment-care tasks around the property, Tools Storage & Organization can help keep replacement fittings plus maintenance gear easier to locate.

Refit the Plug Carefully

More force isn't automatically a better seal.

When reinstalling a compatible plug:

► Clean the fitting
► Clean the drain opening
► Check for visible damage
► Position the plug correctly
► Seat it as intended
► Avoid improvised modifications
► Check for leakage after refilling

Plastic components deserve controlled handling. If a fitting isn't seating normally, stop plus check compatibility, alignment plus condition rather than forcing it.

Test Before Fully Refilling

Why fill the whole trough before discovering the drain point still leaks?

After refitting:

► Add a manageable amount of water
► Inspect the drain area
► Check plug seating
► Watch for seepage
► Reposition only if appropriate
► Investigate persistent leakage

A quick initial check can save water plus time. Once the drain point is holding correctly, continue filling the trough as required.

Keep a Replacement Accessible

A tiny fitting is remarkably easy to misplace when maintenance happens across a large property.

Where drain plugs are regularly removed:

► Store replacements in a known location
► Keep them with relevant trough supplies
► Label compatible spares where useful
► Avoid mixing unrelated fittings
► Check spare condition periodically
► Replace damaged components before they're urgently needed

Small Parts Organisers can provide a practical home for smaller maintenance components that otherwise disappear into drawers, vehicles or workshop benches.

Don't Ignore Persistent Leakage

A drip that never stops can become wasted water plus a permanently wet patch around the trough.

If leakage continues:

► Recheck compatibility
► Clean the drain area
► Inspect the plug
► Examine the surrounding fitting
► Look for cracks or distortion
► Confirm correct seating
► Replace damaged compatible components where required

Look beyond the plug if the obvious fixes don't work. The drain opening or surrounding trough component may be contributing to the problem.

Consider the Surrounding Trough Setup

Reliable livestock water depends on more than the component at the bottom.

Periodically inspect:

► Water supply
► Inlet fittings
► Trough stability
► Mounting or supports
► Drain point
► Water cleanliness
► Surrounding ground
► Signs of animal damage

A well-maintained drain plug is one part of a much larger watering setup. Regular visual checks can help identify issues before they interfere with normal use.

Work Safely Around Livestock Areas

Maintenance becomes harder when animals, slippery surfaces plus tools all occupy the same small space.

Before working:

► Manage animal access where necessary
► Watch for wet ground
► Keep tools organised
► Wear suitable footwear
► Control trip hazards
► Keep removed components accounted for
► Follow safe farm-work practices

Appropriate Safety & PPE can support the maintenance task plus conditions around the trough.

Expert Tips

► Identify the trough before the plug. Product compatibility matters more than visual similarity.
► Check the size carefully. RELN specifies a 20mm drain plug with compatible Multi-Trough water-trough configurations.
► Clean before diagnosing a leak. Sediment or debris can interfere with how a removable fitting seats.
► Inspect both sides of the problem. Look at the plug plus the surrounding drain point.
► Plan where the water will go. Emptying a large trough can quickly saturate the nearby ground.
► Use cleaning time for inspection. Check accessible fittings while the trough is empty.
► Avoid unnecessary force. A fitting that refuses to seat deserves investigation rather than harder tightening.
► Test with less water first. Confirm the drain point is holding before completing the refill.
► Keep compatible spares organised. Small fittings are easier to replace when you know exactly where they are.
► Watch for recurring wet ground. It may point to ongoing leakage or another water-management issue.

► Keep the drain opening clear. Sediment around the lowest point can make maintenance unnecessarily difficult.
► Check the wider trough setup. Supply, supports, cleanliness plus drainage all contribute to dependable use.
► Inspect after moving equipment. Relocation can disturb fittings that previously sat correctly.
► Replace damaged parts promptly. Waiting until the trough needs to hold water urgently makes a small repair more inconvenient.
