Water Systems & Plumbing

Our Water Systems & Plumbing range covers everything for a boat’s onboard water systems: bilge pumps (electric and manual), freshwater pumps, hose and fittings, tank senders and gauges, and water filtration – the plumbing that keeps a boat dry, watered and running.

Bilge pumps are the safety-critical end of this category: an electric bilge pump clears water automatically (paired with a float switch to trigger it) and should be sized to your bilge volume and typical water ingress, while a manual bilge pump is the essential backup if power fails – every boat should have one aboard regardless of electric pump capacity. Freshwater pumps (electric or manual) supply the galley and heads; an electric pressurised pump gives mains-like flow at a tap but draws battery power, while a manual galley pump needs no power at all, useful as a backup or on a simpler boat. Hose, fittings and clips need to be marine-rated rather than generic – the wrong hose or a standard hose clip is a common source of slow leaks and bilge water that’s hard to trace.

Tank senders and gauges let you monitor fuel and water levels rather than guessing, worth fitting or replacing if yours reads inaccurately, since a faulty sender is a common and often overlooked fault. Browse the subcategories below for the full range in each area.

Frequently asked questions

Do I need a manual bilge pump if I already have an electric one?

Yes – a manual pump is the essential backup if your electric pump or its power supply fails, and every boat should carry one regardless of electric pump capacity.

Why is marine-rated hose important rather than standard hose?

Marine hose and clips resist the corrosion and degradation that generic hose suffers quickly in a boat’s damp, saltwater-exposed environment – using the wrong hose is a common cause of slow, hard-to-trace leaks.

My fuel/water gauge reads inaccurately – what’s wrong?

Most often a faulty or failing tank sender rather than the gauge itself – senders are a common wear part and straightforward to replace.
