Before replacing the entire pump I just replaced the cartridge in the old Mayfair housing. then I realized how old and brittle the old housing has become with years of use. When replacing just the cartridge the safety lock tab just snapped off in my hand.I'll just replace the entire pump next time rather than risk failure from old brittle plastic safety tab. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars nice pump *by M***N on Reviewed in the United States on June 25, 2021* works like a champ! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars After 6 months motor keeps coming loose great price fast shipping *by G*** on Reviewed in the United States on June 4, 2023* Pump worked for 6 months. Twist in motor will not lock in place and stays loose and will not work. I switched to this brand because of good ratings and can be easily replaced. This motor can't be replaced because the piece that hold it in is broke or gone. This pump should last me 5 years like the other brand but did not hold up. Twist in pumps did not work out for me --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/4675556-johnson-pumpof-america-28503-johnson-pump-28502-livewell-aerator-cartridge](https://www.desertcart.vu/products/4675556-johnson-pumpof-america-28503-johnson-pump-28502-livewell-aerator-cartridge) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-09*
