Frequently Asked Questions About ZSL Plumbing
When should I be shutting off my outdoor water?
It is recommended to shut off your outdoor water on October 31st (Halloween) and reactivate it on Easter Sunday. This practice helps protect your outdoor plumbing from potential freezing damage during winter months.
High Efficiency boiler vs Standard Boilers?
High efficiency boilers are a modern innovation that require annual maintenance. Standard boilers, on the other hand, are well-established and do not necessitate yearly servicing.
Why do I need water filtration?
Water filtration is essential because tap water often contains impurities such as iron, sand, copper, and other potentially harmful substances. Installing a filtration system not only protects your family's health but also prevents unnecessary plumbing repairs caused by these contaminants.
Are you licensed and insured?
Yes, our company is fully licensed and insured to provide plumbing services in Suffolk County, New York.
Do you offer emergency services?
Yes, we provide 24/7 emergency plumbing services to address urgent issues at any time.
Is it better to get a tank or tankless water heater?
The choice between tank and tankless water heaters depends on your specific needs. Tank water heaters have a lower initial cost but may result in higher energy bills due to constant water heating. Tankless models are more energy-efficient but have a higher upfront cost and may not be suitable for homes with low water pressure.
Why should you use ZSL Plumbing?
ZSL Plumbing is committed to delivering exceptional service with integrity. We strive to offer the highest quality workmanship at competitive prices, ensuring the best value for our customers.
What is this green color thing growing on my copper piping?
The green substance on your copper pipes is likely due to galvanic corrosion. This occurs when dissimilar metals, such as copper and steel, come into contact. If you observe this issue, it's crucial to contact us promptly for professional assessment and resolution.
What are the signs of a slab leak?
Slab leaks occur in pipes beneath a home's concrete foundation. Signs include unexplained increases in water bills, cracks in floors or foundation, warm spots on the floor, and mold growth. If you notice these symptoms, professional inspection is recommended.
Is it better to get a tank or a tankless water heater?
Tank water heaters generally have a lower initial cost compared to tankless models. However, the best choice depends on factors such as your household's hot water needs, available space, and long-term energy efficiency considerations.
