Keep the heads working - the whole crew will thank you. This collection stocks toilet pumps, complete pump assemblies, service kits and individual spares for Jabsco and other common marine toilets: seals, valves, joker valves, pistons, hoses and hardware for both manual and electric sea toilets.
Most marine toilet problems trace back to a handful of inexpensive parts. A stiff pump usually needs the piston seal lubricated or replaced; poor flushing or backflow smells almost always mean a tired joker valve; and an annual service kit keeps everything sweet. Identify your toilet model - usually marked on the pump body or base - and match it to the listed kits. We keep the common Jabsco service parts in stock for fast delivery.
Frequently asked questions
Why is my marine toilet pump stiff to operate?
A stiff manual toilet pump usually means the piston seal is dry or worn - lubricate with a suitable marine lubricant or fit a new seal from the service kit. Never use household oils that attack rubber parts.
What is a joker valve and when should it be replaced?
The joker valve is the one-way rubber valve on the toilet outlet that stops waste flowing back. Replace it annually or whenever you notice backflow or odours - it's the most common cause of toilet problems.
How do I identify my marine toilet model?
Check for a model label on the pump body or toilet base, or match your unit to product photos. A photo of the pump assembly is usually enough for us to identify the right service kit.
