I replaced a re-circ line for a client, water heater and added uponors demand pump with motion sensors. While showering about five minuits into and at approx recurring intervals the water is not going cold but just going to lukewarm for about 5 seconds and then returning to normal temps. this happens in both showers in the house older non pressure balanced valves. I replaced the line with pex could have the velocity increased due to the smaller inside diameter of the pex and could this be effecting the older valves? Any other thoiughts
thanks
