If the diameter of those pipes were small when they were installed, they are still small today. Increasing the size of pipes in your home requires a fundamental overhaul of your plumbing system, and is typically not economical for existing homes and more suited to a house first being built.
Another possible answer is that your pressure-balancing valve may be at fault. A thermostatic mixing valve TMV is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures, preventing scalding. Pressure valves open and close pipes in accordance with water flow. If cold or hot water levels drop, in the event of a toilet flush or a dishwasher cycling on, a faulty pressure valve could make up for the drop in pressure by sending scalding or freezing water through your shower.
Arguably, the cheapest route is to reduce the amount of water going to the toilet by installing more water efficient toilets. You can also reduce the overall amount of water the toilet needs by either buying a low flow toilet, or placing a brick, jug of water, or other object in the tank. However, this method will reduce the amount of water available for each flush, so you may encounter difficulty clearing solids from the bowl.
Relax and be free from anxiety Take back good sleep and help alleviate pain. Installing a new mixing valve in the shower can reduce or eliminate the temperature fluctuations. Thermostatic mixing valves automatically balance the amount of hot and cold water being mixed, which will prevent drastic fluctuations in shower temperature. If the cold water flow is reduced due to a toilet flush , the valve automatically adjusts the amount of hot water being mixed.
This keeps the shower temperature more consistent, even when other fixtures are using water. Increasing the amount of water available in the system can alleviate the problem, but will likely require a major change to the plumbing.
A more drastic solution would be to install a manifold with home runs. This would likely require a major plumbing renovation, with almost all of the plumbing changed. In this type of system, there is a central load balancing manifold. Then for each fixture in the house, a dedicated pipe is run between the fixture and the manifold. In the end, it's all about supply and demand. Sometimes, though these valves wear out, break, or are positioned incorrectly and that can cause uncomfortable shower temperatures.
Because accessing these valves require disassembling your shower fixtures, we suggest leaving a shower valve repair or replacement to a professional. October 19, Schedule Appointment Today.

Although the hot water heater is where you begin to find out why your shower water isn't getting hot, there may be other causes that limit or deny you a hot shower when you want it.
Make sure the water heater temperature is set correctly. If the water in the shower never gets hot, the problem may be with the temperature control on the water heater. If you have an electric water heater, one of the elements may have burned out and the water either gets hot for only a short length of time, or it never gets hot at all.
On older water heaters, the cold water supply dip tube may have deteriorated. Instead of the incoming cold water going straight to the burner for heating, a compromised dip tube may send cold water directly up to the hot water feed pipe. When that happens, you won't get any hot water. A quick check for that malady is to examine faucet strainers for any bits of plastic pieces that have been caught.
Plastic bits caught by a faucet strainer is a sure sign your dip tube has deteriorated and is beginning to break apart.
