Water Heater – The Hard Water Impact Centre

The water heater sits at the intersection of every hard water problem in a Severna Park home. Chesapeake Bay mineral content precipitates inside the tank every time water is heated, sediment accumulates at the tank bottom, and the anode rod (the sacrificial component protecting the tank interior from corrosion) depletes faster in hard water conditions than in soft water areas.

Annual maintenance for a Severna Park water heater:

• Sediment flush via the drain valve (extends tank life and maintains efficiency)
• Anode rod inspection (should be replaced before it’s fully depleted – once the core wire is exposed, tank corrosion begins)
• T&P valve test (pull the lever briefly to confirm the valve opens and reseats cleanly – a T&P valve that doesn’t reseat requires immediate replacement)
• Expansion tank pressure check

We perform all four as a maintenance service call. For most Severna Park homes with water heaters over 8 years old, this visit either gives you a reliable remaining service life estimate or identifies that replacement is the more cost-effective path.

Expansion Tank – Required and Often Missing

Anne Arundel County requires an expansion tank on all water heater installations in closed plumbing systems – a “closed system” means a backflow preventer is installed on the main water supply (which is standard on all newer installations in the county). Without an expansion tank, thermal expansion from heating water has nowhere to go – pressure builds in the system and stresses the water heater and all connected fixtures.

Expansion tanks have a pre-charged air bladder that absorbs expansion. The bladder degrades over time – typically 5–7 years – and needs replacement at that interval. A failed expansion tank bladder means the system is again without thermal expansion relief. We check expansion tank air pressure on every water heater service call.

Pressure Reducing Valve (PRV) – Does Your Severna Park Home Have One?

Main water supply pressure in Severna Park typically runs 60–80 PSI from the municipal main. Most home plumbing fixtures are rated for 80 PSI maximum; above 80 PSI, fixtures wear faster, supply lines are more likely to fail, and water hammer noise becomes common.

A pressure reducing valve installed at the main supply entry reduces inlet pressure to the 50–65 PSI range most plumbing systems operate best at. PRVs have a service life of 10–15 years – a failed PRV either loses its pressure-reducing function (supply pressure rises toward line pressure) or fails closed (water pressure drops throughout the house). Both are diagnosable with a pressure gauge at a hose bib.

For homes in Severna Park without a PRV – common in older construction that was built when supply pressures were lower – high supply pressure is silently stressing every fixture, supply line, and appliance in the home.

Main Shutoff Valve – Does It Actually Work?

The main water shutoff is the most important valve in a Severna Park home for emergency response – and the most frequently found to be seized or only partially functional when it’s urgently needed.

Original ball valves and gate valves in older Severna Park homes that haven’t been operated in years frequently seize from mineral scale and corrosion. A gate valve (round handle, multiple turns to close) that hasn’t been operated in 10+ years should be tested before it’s needed – and replaced with a modern quarter-turn ball valve if it shows any resistance to operation.

On every service call in a Severna Park home, we confirm the homeowner knows where the main shutoff is located and test it briefly. If it doesn’t close fully and freely, we recommend replacement on that visit. A shutoff that requires a plumbing call to find is not useful during a burst pipe.
