Antifreeze Hand Pump Kit | CAMCO-36003

Camco Antifreeze Hand Pump Kit | Part #36003 | Marine & Boat Winterization | Pumps Antifreeze Through Plumbing Systems

Winterizing your boat's freshwater plumbing, livewell, raw water washdown, and head systems requires getting antifreeze into every line and fitting before temperatures drop. The Camco #36003 antifreeze hand pump kit makes that job straightforward — no electrical power needed, no improvised funnels or gravity-feed setups. Simply connect the inlet tube to your antifreeze jug, connect the outlet to the intake fitting or hose you're winterizing, and pump antifreeze through the system until it flows out the other end. CSA lead-free certified and compliant with federal and state drinking water safety standards.

Additional Information

Why Proper Marine Plumbing Winterization Matters:

Water expands as it freezes. Any water left in your boat's plumbing lines, fittings, pumps, or through-hulls during a hard freeze will expand and crack those components — repairs that are far more expensive than a jug of antifreeze and a hand pump. Marine systems that must be winterized include:

• Freshwater plumbing and holding tanks — water pumps, lines, faucets, and any holding tank with residual water
• Marine head (toilet) systems — the pump, hoses, and seacocks must be flushed with antifreeze
• Raw water washdown systems — the pump and all lines from the through-hull to the nozzle
• Livewells and baitwells — any standing water in pumps and lines will freeze
• Air conditioning sea water loops — on boats with marine AC, the raw water circuit must be flushed

The Camco 36003 hand pump lets you push antifreeze through each of these systems individually and completely, with control over flow rate and direction that gravity-feed methods don't provide.

What's Included and How It Works:

The kit includes a hand pump, an inlet tube that drops into your antifreeze jug, and a flexible outlet tube that connects to the intake side of the system you're winterizing. Pump the handle to draw antifreeze from the jug and push it through the connected line or fitting until antifreeze exits at the far end of the circuit — confirming the entire run is protected.

Frequently Asked Questions

1. What type of antifreeze should I use with this pump for marine winterization?
Use non-toxic propylene glycol-based marine antifreeze (pink) rated to the lowest expected temperature in your storage environment — typically -50°F for cold climate storage. Do not use automotive ethylene glycol antifreeze (green or orange) in potable water systems, head systems, or any system that contacts drinking water. Always follow the antifreeze manufacturer's dilution instructions.

2. Can I use this pump to winterize my raw water engine cooling system?
This hand pump is designed for low-pressure plumbing systems like freshwater lines, head systems, livewells, and washdowns. Raw water engine cooling system winterization on inboard and sterndrive engines typically requires a different method — most commonly running the engine on a flushing adapter connected to a antifreeze supply, or draining the system completely. Consult your engine service manual for the correct raw water winterization procedure for your engine.

3. How do I know when I've pumped enough antifreeze through a line?
Pump antifreeze through the system until you see pink antifreeze flowing out of the far end of the circuit — the outlet fitting, faucet, or pump discharge. This confirms antifreeze has displaced all water throughout the entire line. For head systems, flush until pink antifreeze exits at the holding tank or overboard discharge.

4. Is this pump reusable season to season?
Yes — the Camco 36003 is a durable, reusable pump. After use, flush the pump and tubes with clean water, allow to dry, and store with the rest of your winterization kit for next season.
