Hi everyone, I am replacing my whole house water filter housing and can't decide between the small or large canister. I presently use a small canister that has 3/4" inlet/outlet. When the unit is apart I can tell the water opening is reduced to 3/8" on inlet and outlet side. Appears to be this way to allow for the bypass valve to fit within the head. All the small ones with the bypass valve appear to be made this way. The larger canister by ge without bypass goes from 1" inlet/outlet to about 3/4" or maybe even no reduction at all. The filters are pricey and I have noticed poor reviews on them. I need a filter due to high sediment. Can't go without one. Does the reduction from 3/4" to 3/8" kill the water pressure? Thanks
