you definitely can conveniently do it without any problem. There are actually two caps are comes with a particular softening unit. These caps play an important role to attach your bypass value with your man pipe system. Another advantage is that some systems are actual water filters that will purify your water to the fullest and not leave any taste to your water. I would still recommend a water purifier by the faucet because this water softener only removes stuff from before it hits the pipes within your house. Right after the softened water gets into your actual house's pipes there still may be some gunk that needs to become filtered.
