Methods to minimize scaling in water filtration systems
A method for water filtration to reduce scaling is disclosed herein. The method includes determining that a pump has been inactive for a threshold period of time. The method also includes closing a first valve to a filtered drinking water tank and opening a second valve to a source water tank based on determining that the pump has been inactive for the threshold period of time. The method further includes activating, based on the first valve being closed and the second valve being opened, the pump for a period of time to circulate water from the source water tank through a filter system and back to the source water tank.
1. A method to reduce scaling in a water filtration system, the method comprising:
determining that a pump has been inactive for a threshold period of time;
determining, based on determining that the pump has been inactive for the threshold period of time, that a first valve to a filtered drinking water tank is closed;
determining, based on determining that the pump has been inactive for the threshold period of time, that a second valve to a source water tank is open; and
activating, based on the first valve being closed and the second valve being opened, the pump for a period of time to circulate water from the source water tank through a filter system and back to the source water tank.
2. The method of claim 1 , further comprising periodically opening and closing the second valve in bursts while the pump is activated to create changes in pressure and water flow within at least portions of a loop formed by the pump, the filter system, and the source water tank.
3. The method of claim 2 , wherein periodically opening and closing the second valve in bursts comprises opening and closing the second valve in progressively shorter increments.
4. The method of claim 1 , wherein the threshold period of time is greater than 60 minutes.
5. The method of claim 1 , wherein the period of time to circulate water from the source water tank through the filter system and back to the source water tank is about 2 minutes.
6. The method of claim 1 , wherein the first valve comprises a forward check valve.
7. The method of claim 1 , wherein the second valve comprises a return check valve.
8. A water filtration system, comprising:
a controller configured to:
determine that a pump has been inactive for a threshold period of time;
close, based on determining that the pump has been inactive for the threshold period of time, a first valve to a filtered drinking water tank;
open, based on determining that the pump has been inactive for the threshold period of time, a second valve to a source water tank; and
activate, based on the first valve being closed and the second valve being opened, the pump for a period of time to circulate water from the source water tank through a filter system and back to the source water tank.
9. The system of claim 8 , further comprising periodically opening and closing the second valve in bursts while the pump is activated to create changes in pressure and water flow within at least portions of a loop formed by the pump, the filter system, and the source water tank.
10. The system of claim 9 , wherein periodically opening and closing the second valve in bursts comprises opening and closing the second valve in progressively shorter increments.
11. The system of claim 8 , wherein the threshold period of time is about 60 minutes.
12. The system of claim 8 , wherein the period of time to circulate water from the source water tank through the filter system and back to the source water tank is about 2 minutes.
13. The system of claim 8 , wherein the first valve comprises a forward check valve.
14. The system of claim 8 , wherein the second valve comprises a return check valve.
15. A method to reduce scaling in water filtration system, the method comprising:
determining that a pump has been inactive for a threshold period of time;
determining, based on determining that the pump has been inactive for the threshold period of time, that a first valve to a filtered drinking water tank is closed;
activating, based on the first valve being closed, the pump for a period of time to circulate water from a source water tank through a filter system and back to the source water tank.
16. The method of claim 15 , wherein the pump is periodically activated and deactivated in bursts.
17. The method of claim 16 , wherein periodically activating and deactivating the pump in bursts comprises activating and deactivating the pump in progressively shorter increments.
18. The method of claim 15 , wherein the threshold period of time is greater than 60 minutes.
19. The method of claim 15 , wherein the period of time to circulate water from the source water tank through the filter system and back to the source water tank is about 2 minutes.
20. The method of claim 15 , wherein the first valve comprises a forward check valve.
