📦 Whale Gulper 220 Shower Waste Pump – 12V Non-Clog Electric Grey Water Removal for Marine & RV
Upgrade your onboard wastewater system with the Gulper 220, a proven non‑clog electric pump engineered specifically for grey water applications, including shower drains, sink waste, and washbasin discharge. Unlike conventional bilge pumps that choke on hair, soap residue, and gel particles, the Gulper uses patented non‑choke valves that swallow typical shower debris without a filter to clean or block. The double outlet valve design ensures a smooth, continuous flow of up to 14 liters (3.7 US gallons) per minute while drawing minimal 12V power. Self‑priming to a depth of 3 meters and capable of running dry without damage, it handles the irregular duty cycle of a shower pump—short bursts of water mixed with air—without overheating or losing prime. The compact, multi‑position head rotates for easy installation in tight bilge compartments, under shower trays, or inside RV service bays. Backed by a 2‑year warranty and built from marine‑grade materials in a robust sealed housing, the Gulper 220 replaces unreliable filter‑dependent pumps that demand constant cleaning. Install it and forget about clogged shower drains forever.
🔧 Filter‑Free, No‑Clog Design: Non‑choke valves swallow hair, soap, and debris that jam conventional pumps.
✨ Key Features of the Gulper 220 Grey Waste Pump
- Patented Non‑Choke Valve Technology: Swallows hair, soap curds, and gel without a filter to clean or unblock—the defining feature that separates it from standard bilge pumps.
- Dual Outlet Valve System: Two valves work in tandem to deliver a continuous, surging‑free flow even when the pump pulls in air mixed with water.
- Self‑Priming up to 3 m (10 ft): Mounts well above the shower tray or bilge without losing suction, simplifying installation in cramped compartments.
- Dry‑Run Safe: Unlike many impeller pumps that destroy themselves running air, the Gulper can cycle dry without damage—perfect for draining a shower basin completely.
- 12V Low Power Draw: Moves up to 14 L/min while sipping battery power, ideal for cruising boats, yachts, and off‑grid RVs.
- Rotatable Multi‑Position Head: The pump head rotates to suit your hose routing, making tight‑space installation straightforward without cutting access panels.

❓ Frequently Asked Questions – Gulper 220 Shower Pump
Q: How is the Gulper 220 different from a standard bilge pump?
A: Standard bilge pumps use a spinning impeller that tangles hair and clogs with soap residue. The Gulper uses flexible non‑choke valves that open wide to swallow debris, then seal tightly to pump. No filter to clean, no impeller to jam—it's built specifically for grey water that contains solids.
Q: Can I mount this pump above the shower tray, or does it need to sit below the waterline?
A: The Gulper self‑primes up to 3 meters (10 feet) vertically, so you can mount it well above the shower basin—inside a vanity cabinet, behind a bulkhead, or in a service bay. This makes retrofit installations much easier than pumps that must sit below the drain level.
Q: Will it hurt the pump if it runs dry after the shower water is drained?
A: No. The Gulper is engineered to run dry or pump a mix of air and water without damage. It will continue to cycle until the shower tray is fully evacuated, then shut off without overheating or wearing the seals.
Q: How often do I need to clean or service this pump?
A: There is no routine cleaning required—no filter to remove, no impeller to untangle. If the pump ever fails to prime (extremely rare), a quick inspection of the duckbill valves takes minutes with basic tools. The non‑choke design means most owners never touch the pump for years after installation.
Q: Can I use this for my galley sink drain as well as the shower?
A: Yes. It handles both shower and galley grey water, including food particles, soap, and grease. For galley use, occasional hot water flushing will help keep the valves clean. It is not designed for black water (toilet waste)—use a dedicated macerator pump for that application.
