Bilge Pickup Maintenance: Clean, Inspect, Replace

Bilge Pickup Maintenance: Keep Water Moving

Regular pickup maintenance helps an Arid Bilge System remove residual water. Inspect the pickup, clear accumulated debris and check its condition before putting it back in service.

Build pickup inspection into your regular bilge checks, following the instructions for your installed model. Check sooner after construction work, contamination or a zone alarm.

Watch: Cleaning Debris from a Pickup

In this short Arid video, Alfred checks pickups restricted by construction dust, explains the zone alarm and demonstrates cleaning them. It is a useful companion to the inspection routine below.

Why Debris Collects at the Pickup

Debris naturally moves toward the lowest point in a bilge because bilge water carries it as it flows. Since the pickup is installed at that low point, debris may collect around the pickup.

The pad beneath the pickup helps keep debris out of the intake tubing. Inspect the pad and the area around it: removing accumulated material at this accessible point helps keep the intake clear.

That is a much easier service point than a blockage deep inside the intake tubing or inside the unit itself.

How Often Should Pickups Be Cleaned?

Use the maintenance instructions for your installed model to set the routine, and clean a pickup when debris or residue restricts its intake.

Some boats may need more frequent attention, especially if they operate in a dirty or oily bilge environment.

Situations that may call for more frequent pickup cleaning include:

New boat construction debris
Fiberglass dust
Paint chips
Heavy bilge contamination
Dirt buildup on older boats
An alarm tied to restricted pickup flow
Excessive sediment or debris accumulation

New builds and older boats sit at opposite ends of the same problem. A new boat may shed fiberglass dust, paint chips, and construction debris. An older boat may have years of accumulated dirt and residue. Both conditions can send more material toward the pickup than a clean, settled bilge environment.

Oily Bilges Need a Closer Eye

In older boats, oily bilge environments, or vessels with heavy sludge buildup, the Scotch-Brite-style filter pad on the bottom of the pickup may collect oil, dirt, and debris faster than it would in a clean bilge.

Recurring contamination needs attention at its source as well as at the pickup. Cleaning the pad will not repair an oil leak or remove residue elsewhere in the compartment.

For those boats, inspect more often.

Check the pad, seal, fitting and body for lifting, separation or visible damage. Follow the model instructions for cleaning, and ask Arid or your installer about any material that remains heavily contaminated.

Check the Pickup When a Zone Alarms

A zone alarm needs investigation. One possible cause is debris restricting the pickup, so check its screen and filter area first.

If the pickup is dirty, remove it, clear the debris, rinse it and reinstall it according to the system instructions. Cleaning can restore fluid entry and airflow when a restriction is the cause.

If the alarm continues, check pickup placement, the tubing path and system operation. Contact Arid or your installer if you cannot identify the cause.

Cleaning After Contamination

Before using a cleaner on the pickup, confirm that it is suitable for the installed model. Follow the product instructions rather than assuming that a cleaner intended for another onboard component is suitable for the pickup.

After contamination, inspect the pad, seal, fitting and body. If a part has deteriorated or cannot be cleaned, ask Arid or your installer about replacement before returning the system to service.

When to Replace Instead of Clean

Replace a pickup with a damaged body, fitting, seal or filter pad. A loose or separated pad should not be treated as a cleaning problem. If the pickup remains restricted after cleaning, have the pickup and tubing checked before deciding which part needs replacement.

Base replacement on condition and the guidance for your installed system. This article does not set a fixed service life for every pickup.

The Short Version

Inspect the pickups during routine bilge checks and after contamination or construction work.
Investigate a zone alarm; a restricted pickup is one possible cause.

Use cleaning products suitable for the installed system. Replace damaged parts rather than repeatedly cleaning a compromised pickup.

Frequently Asked Questions

How often should I clean my pickups?

Follow the routine for your installed model and check the pickup during regular bilge inspections. Clean sooner when debris or residue restricts the intake.

New builds with fiberglass dust and older boats with years of buildup may need more frequent cleaning.

My system alarmed on one zone. Did it fail?

A zone alarm can have several causes; inspect the pickup before assuming the unit has failed.
If debris restricts the pickup, remove the debris, rinse the pickup and reinstall it according to the system instructions.
If the alarm continues after the pickup is cleaned, inspect the tubing path, pickup placement, and system operation.

Why does debris collect around the pickup?

Arid Bilge Systems are designed to be simple to maintain because the pickup acts as the first-stage filter point.

Instead of allowing debris to travel deep into the intake tubing or internal system components, debris can collect at the pickup where it is easier to inspect, remove, and rinse.

Clear the surrounding debris as well as the pickup itself so the next cycle does not immediately draw loose material back toward it.

Can I drill a hole in the pickup to mount it?

No.

Drilling damages the pickup body, screen, filter area, and internal flow path. It can also allow debris, fiberglass dust, or drilled material to enter the vacuum intake line.

Use gentle downward tubing tension or an approved bracket instead.

Should I clamp the pickup down tightly?

No.

The pickup needs to breathe. Fluid and air must be able to enter freely for the system to complete its cycle.

If the pickup is over-clamped or compressed, the grooves or intake area may become restricted, and the zone may not clear properly.

When should I replace a pickup?

Replace a pickup with a damaged pad, seal, fitting or body. If an intact pickup remains restricted after cleaning, have it and the tubing checked before deciding which part needs replacement.

If the pickup body, screen, fitting, filter pad, or seal area is compromised, replacement is the safer option.
