The navien needs to have a .5 gallon per minute to turn heater on, the flow rate will probably be too low. Check your model, navien does make a tankless that has recirculating pump installed. They also have their own thermonic tees that you can install if you don’t have a hot water recirculating line. **Q: how to get operating instructions** A: Operating instructions come with the Grundfo's 595916. **Q: Does this have a button that can be pressed to turn the pump on and cycle the water?** A: There is a switch as a part of the timeclock that can turn the pump to On. Auto, or Off. Then look at the perimeter of the timeclock at the little switches, I think there are four per hour. If you push them toward the center the pump will not run at that time; the pump will run during the times when the switches are in the position farther away from the center. **Q: Plumber said we needed additional parts under kitchen sink and bathroom. Correct?** A: Additional hoses to couple the bypass device at the farthest sink connection. Of course the pump is located at the hot water heater. ## Frequently Bought Together - Grundfos 595916 1/25 Horsepower Comfort Series Recirculator Pump, Model: 595916, Outdoor & Hardware Store - Grundfos 595926 Valve, Black - Water Line Adapter, 4 PCS Pipe Fittings in 1/2" Female to 3/8" Male Reducer Adapter, Compression Fitting for Kitchen Bathroom Faucet Supply Hose, Stop Valve Pipe Connector With Rubber Washer --- ## 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.jp/products/165061759-595916-1-25-horsepower-comfort-series-recirculator-pump-model-595916](https://www.desertcart.jp/products/165061759-595916-1-25-horsepower-comfort-series-recirculator-pump-model-595916) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-15*
