Get It Done Right: How to Change Hot Water Tap with Combi Boiler in Minutes!

Are you tired of that perpetually lukewarm shower or the frustratingly slow drip from your kitchen faucet? A faulty hot water tap can be a real pain, especially when you have a combi boiler powering your home. But don’t despair! This guide will walk you through the process of changing a hot water tap with a combi boiler, giving you the confidence to tackle this common plumbing task.

Understanding Your Combi Boiler

Before diving into the replacement process, it’s crucial to understand how your combi boiler works. Unlike traditional systems with separate hot water tanks, a combi boiler heats your water on demand. This means the boiler needs to be switched on to provide hot water, and any issues with the tap can directly affect your hot water supply.

Safety First: Shutting Off the Water Supply

The most important step in any plumbing project is safety. Before you start, make sure you shut off the water supply to the affected tap. This is usually done by turning the isolating valve located near the tap itself.

Identifying the Tap Type

There are two main types of hot water taps:

• Compression Taps: These older models use a rubber washer to control water flow. They are typically identified by a single handle and a square-shaped spindle.
• Ceramic Disc Taps: These modern taps use ceramic discs to regulate water flow. They are usually identified by a smooth, round spindle and may have multiple handles.

The type of tap you have will determine the specific steps involved in the replacement process.

Gathering the Necessary Tools

Before you begin, make sure you have the following tools on hand:

• Adjustable Wrench: For loosening and tightening nuts and fittings
• Basin Wrench: For reaching hard-to-access nuts under the sink
• Screwdriver: For removing screws and securing the new tap
• Pipe Wrench: For loosening and tightening pipes
• Teflon Tape: For sealing pipe threads
• New Tap: Ensure it’s compatible with your existing plumbing and has the same number of handles and functions
