Where does the cold water line go in a house?

The cold water service line slopes away from the water heater after splitting from the main line. Instead of sending water through the heater, cold water service lines run directly to every water appliance in the home.

How to refill a direct cold water storage system?

To refill a direct cold water storage system open all cold taps/faucets, close off all hot taps/faucets and any drain valves then open main stop-valve. Once the water is running freely from the cold taps/faucets close them off one by one and continue filling the cold water storage cistern/tank and hot water cylinder.

How can I protect my direct and indirect cold water systems?

However, this can easily be protected against in both the direct and indirect cold water system by installing a non-return valve or check valve immediately after the main stop-valve supplying water to the house. This would be good practice.

What’s the difference between hot and cold water lines?

These paths are called the hot and cold service lines. The cold water service line slopes away from the water heater after splitting from the main line. Instead of sending water through the heater, cold water service lines run directly to every water appliance in the home.

What can I do about hot water coming out of cold taps?

If the cold water intake line is comprised of PVC or similar plastic pipe, either directly from the heater or above the initial copper pipe, you can also make an “improvised” heat trap by incorporating a 6-12″ vertical drop in the line. Recall that the problem is convection–hot water’s tendency to rise upward.

How does hot water rise back into cold water?

1 At the recirculating manifold, if you have a hot water recirculating system. 2 At the hot water heater. Without proper heat traps, hot water can rise back into the cold water line through the process of convection. 3 At any single-handle or mixer faucet fixtures.
