There are other Wale Gulper pumps that are submersible. **Q: do you do a pipe flow sensor to fit on the shower pipes so it starts pumping as soon as the waters running in?** A: this type of pump is normal control by some sort of float switch that sits in the bilge, or may be via a 'Shower Sump System' **Q: What size fuse should I use with this? Am using it as a battery backup sump pump.** A: on the 12volt side, I think I fitted a 10A cartridge fuse, but I must say it was years ago, however ,as a guide have a look at the size of the cable supplied with the pump, ie 1.5 mm cable can carry 14A, hope this helps **Q: hi, does it blow air into say a water drain, or does it suck air and water out from the water drain? thx** A: Hi Joseph, the Whale Gulper pumps a mixture of air and water from the water drain. E.g. on a boat, it would such the water out of the bath/shower stand and pump it outside. It works well and is commonly used by boaters. ## Frequently Bought Together - Whale Gulper 220 Graywater Pump - Manages Gray Waste in Boats & RV - 3.5 GPM Flow Rate - 12V/24V - Whale AK1550 Gulper® 220 Service Kit Replacement Parts - Rule 35A Marine Rule-A-Matic Switch (Mercury Free) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/51441880-gulper-220-graywater-pump-manages-gray-waste-in-boats-rv](https://www.desertcart.hr/products/51441880-gulper-220-graywater-pump-manages-gray-waste-in-boats-rv) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-17*
