Yesterday I installed a water filter on my 1995 Hunter Legend between the water tank and the sediment filter, the filter has 3/8" lines and the water lines are 1/2". After the installation I noticed that my water pump (annoying) sound is less and more cushioned and takes a little more time to build up the pressure. Am I damaging the water pump by restricting the water flow 1/2" to 3/8" ?, any thoughts on this addition? Any help will be greatly appreciated.Gene
