I live on the 6th floor of a pre-war apartment building in Queens NY. Since moving in, I've noticed that the water temperature in my shower fluctuates wildly, from uncomfortably hot to uncomfortably cold. When I brought this to the attention of my landlord, he said that it was caused by other tenants flushing their (tankless) toilets, which caused an evacuation of the cold water in the pipes, causing the water in the shower to become momentarily hot. This would only account for the times when the shower becomes too hot, not when it becomes too cold. Also, the duration of these fluctuations is sometimes much longer than a few seconds. At times, I would estimate the temperature lasting for at least 30 seconds. My question is, is there anything that can be done inside my shower to help with this problem? I've read online about 'thermostatic control valves,' but I don't know if such a device would work for me.
