Understanding the Impact of Climate on Running Plumbing Above a Slab Foundation
Climate plays a significant role when deciding to run plumbing above a slab foundation, especially in sunny Anaheim Hills.
Effects of Temperature Changes
Temperature fluctuations in our beautiful California weather can cause plumbing materials to expand and contract, which may lead to leaks if not installed correctly.
