When to Call a Plumber vs. DIY

Overview

Some plumbing jobs are safe to DIY. Others can cause thousands in damage if done wrong. Here is how to decide. This guide covers everything Dallastown and York County homeowners need to know, based on real-world experience servicing homes in the area.

We see this issue regularly in York County homes. The combination of hard water (15-20 GPG), aging infrastructure in homes built before 1970, and seasonal temperature extremes creates plumbing conditions that national guides do not address.

What You Need to Know

The key factors that affect this topic for Dallastown-area homeowners include water hardness, pipe material and age, local building codes, and seasonal weather patterns.

York County water is sourced from a mix of surface water and groundwater, with mineral content that varies by municipality. Dallastown, Red Lion, and surrounding boroughs typically test at 15-20 grains per gallon, well above the 7 GPG threshold where a water softener is recommended.

Homes built before 1970 in the Dallastown area commonly have galvanized steel supply lines and clay sewer laterals. These materials interact with hard water differently than modern PEX and PVC, creating issues that newer homes do not experience.

York County Considerations

What makes this different in York County compared to national averages:

• Hard water impact: 15-20 GPG mineral content accelerates wear on plumbing components, fixtures, and water-using appliances. Scale buildup reduces pipe diameter and restricts flow over time.
• Housing age: Much of Dallastown's housing stock predates 1970. Galvanized pipes, clay sewers, and outdated fittings are common. These require different repair approaches than modern materials.
• Winter temperatures: January and February lows of 20-25 degrees F create freeze risk for exposed pipes in crawl spaces, exterior walls, and unheated garages.
• Local contractors: National franchises operate in the area but use generic templates and distant dispatch. Local plumbers who know the specific conditions produce better outcomes.
