Do you need a leaky pipe or fixture repaired? Or do you just want to upgrade your faucets or valves? At KHK Construction, we can handle any of your plumbing needs. **Helpful tips: Preventative care and proper maintenance is paramount when it comes to your plumbing. A bad pressure regulator can cause damage to your pipes (often the source of under-slab leaks) and plumbing fixtures. Corroded shut-off valves and supply hoses are another source that can lead to more extensive damage resulting in more-costly repairs.
