So, yes it will work **Q: WHEN SENSOR VALVE CLOSES, DOES PUMP SHUT OFF?** A: The recirculating pump runs continuously when turned on. The valve simply controls when hot water begins to seep into the cold water line which is what makes the hot water always available at faucets with the valves installed. Depending on the pump you have, you can either program it to run 27/7 or as I do, program the timer on the pump to be on at certain times and off otherwise. Mine is programed to be on from 7 am to 9 am, then again from 9 pm until 11 pm. I also can override the timer when I need hot water at unanticipated times. If you run the pump continuously, it will greatly increase the amount of energy used to keep the water heated. Hope that helps. **Q: i have installed the recert pump and have it running 24/7, there is excellent hot water but i am also getting warm/hot water on the cold water side?** A: Hi Mark, What is happening to you is absolutely normal, since the mentioned valve discharges al the hot water line into the cold one, and as in your case you have it running all the time, eventually the cold water line fills with mild hot water. You have two problems there, 1.- the pump consumes electricity on a constant basis and 2.- since the heat on the cold water line cools down eventually, you end up more electrical power, since the heater ends up cooling down and swithing on once more, to keep up with the energy wasted in maintaining both hot and cold water lines warm...What I did was simple; I installed a wireless remote control in both bathrooms and every time I need to use either, I press the ON button, and it takes about 40-60 seconds to warm-up the hot water lines. Before I leave the facilities I press the OFF button and that's it. These remote controls are dirt cheap in any electronic dealer (I got mine from China), and it works like a champ.Best regards **Q: how long is the warrenty on the valve?** A: We have replaced this valve about every 2 years and it’s annoying. Our circulation pump runs about 16 hours a day. There is one valve under a bathroom sink at the furtherest of the house for hot water recirculation. ## Frequently Bought Together - 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.tn/products/7920317-grundfos-64376-comfort-valve-used-to-be-part-595-comfort](https://www.desertcart.tn/products/7920317-grundfos-64376-comfort-valve-used-to-be-part-595-comfort) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-13*
