Plumbing Systems

From faucets to drains and everything in between, Weismiller Plumbing & Heating has the solutions you need to handle even your most complex plumbing problem. Our master plumbers can do it all: troubleshoot problems, provide regular maintenance for optimal performance, and install new systems to save you money every time you turn on the tap. Plus, we offer 24-hour emergency service and affordable prices to suit nearly any budget.

Heating Systems

Staying warm when those cross-island winter winds start to blow means you need a heating system that’s up to the task. We carry a wide range of heating system components, including energy-efficient furnace models your budget will love. And we also provide complete repair and maintenance services to keep your system — old or new — working like it should.

Backflow Prevention Devices

Backflow prevention devices are designed to ensure that messy sewer backups don’t wind up flooding your home. Instead, fluids and solids are diverted to a special cleanout area, so they can be removed. Most codes require installation of a BPD whenever a bathroom is remodeled or a new bathroom is added on to your home, and our master plumbers have plenty of experience in proper BPD installation.
