This must be plumbing question week.
I'm asked to install a Fleck 5600 softener at my Son's house.
The main water line to the house is copper and passes above where the unit will sit in the garage. To reduce the time stress of having no water in the house and for other reasons I'm considering a three ball valve setup as shown.
Pros: after getting the ball valves installed the 5600 can be installed without a time constraint, in the future if there is a leak or the unit needs replacing/etc. water to the house can easily be enabled.
Cons: cost of valves, fittings, pipe and soldering time
Any advice is appreciated.
Thanks.
