Low Water Pressure
#1

I recently replaced the pipes in a moble home. I used a 3/4" CPVC
pipe coming from the City water connection to the trailer connection then I switched from 3/4" to 1/2" CPVC pipe under the trailer. The connection is at the bathroom. At the bathroom is the water heater, washer, toilet, sink, shower/tub. The water pressure is okay going to the water, heater, sink, and also the toilet. The water pressure between the toilet to the washer and the shower/ tub drops and on to the kitchen sink. When you turn the water on it has some water pressure then after about 5 seconds it drops to a slow stream. I thought maybe I had put the T connection in the wrong place and changed it, it didn't help. Any help would be greatful, thank you.
