What is an IH Hewitt Bypass Kit and Why Do You Need It?

So, what exactly is this IH Hewitt bypass kit all about? In simple terms, it's a clever mechanism designed to maintain proper water flow within your heating system, especially if a component like the pump or a zone valve fails. Essentially, the bypass kit creates an alternative route for the water to circulate, preventing the system from locking up or causing other issues when certain parts aren't functioning correctly. Think of it as a detour on a road trip – when the main road is blocked, you take the bypass to keep moving. The primary function of the bypass kit is to maintain heat circulation even when a component fails. This is particularly crucial during the colder months when a malfunctioning boiler can quickly turn your home into an icebox. The bypass kit allows the system to continue circulating hot water, providing heat to your radiators or underfloor heating, thus maintaining a comfortable temperature while you arrange for repairs. Another benefit of the bypass kit is that it can help to prevent the build-up of sludge and debris in the system. The constant circulation helps to keep the water clean, which can extend the life of your boiler and other components. It's like giving your heating system a regular cleaning, preventing blockages and ensuring it operates efficiently. By installing a bypass kit, you are essentially buying some time, allowing you to avoid the need for immediate, costly repairs or replacement, especially if your boiler is otherwise in good condition. Therefore, it is important to remember to inspect your heating system regularly and if necessary, contact a qualified technician to make sure everything is working properly. The IH Hewitt bypass kit can be a game-changer, especially for older boiler systems, where component failures are more common. By understanding what it is and how it functions, you can make an informed decision about whether it’s the right solution for your heating woes.

Alright, before we get our hands dirty, let's gather our arsenal. Having the right tools and materials beforehand is key to a smooth and successful installation. Here’s a checklist to make sure you're well-equipped:

• IH Hewitt Bypass Kit: This is, obviously, the star of the show! Make sure you get the correct kit model for your specific boiler model. Check the manufacturer's instructions to confirm compatibility. This is the heart of the operation. So, make sure you have the right one. Not all kits are created equal; the specific components and design will vary based on your boiler’s model.
• Wrench Set: A good set of wrenches (both adjustable and fixed) will be essential for loosening and tightening pipe fittings. A variety of sizes will cover most eventualities, enabling you to deal with different types of fittings and connections you might encounter during the installation.
• Pipe Cutter: You'll likely need to cut some pipes to accommodate the bypass kit. A pipe cutter will give you clean, precise cuts. A good pipe cutter ensures you get the precise cuts needed for a proper fit and a leak-free seal.
• Screwdrivers: Both flathead and Phillips head screwdrivers will come in handy for various tasks, from removing access panels to securing components. Be sure to have a few sizes to deal with different screw types.
• Pliers: Pliers are versatile tools for gripping, bending, and cutting. Needle-nose pliers can be particularly useful for those tight spaces. They help you to grip components firmly and maneuver them into place, especially when working in confined areas.
• Pipe Fittings: Depending on your setup, you might need additional pipe fittings (elbows, couplings, etc.) to connect the bypass kit to your existing system. Have a selection on hand, in case you need them. Ensure the fittings are the correct type and size for your pipes to guarantee a tight and leak-free connection.
• Teflon Tape (Plumber's Tape): This is your secret weapon against leaks! Use it to seal threaded connections. Wrap it around the threads of pipe fittings before screwing them together. This will help create a watertight seal and prevent leaks. Always wrap the tape in the correct direction to avoid unraveling during installation.

• Optional - Soldering Kit: If the kit requires soldering, have a soldering iron, solder, and flux on hand. This is for copper pipe systems, which use soldered joints. If you are not familiar with soldering, consider having a professional perform this step. Also, ensure you have appropriate ventilation, as soldering can release fumes.

With these tools and materials in hand, you'll be well-prepared to tackle the IH Hewitt bypass kit installation. Remember to double-check everything, and don’t be afraid to ask for help if you need it.

Step-by-Step Installation Guide

Alright, let's get down to the nitty-gritty and walk through the step-by-step installation of your IH Hewitt bypass kit. This is where the magic happens, so pay close attention. Remember, every boiler and system is unique, so always refer to the specific instructions provided with your bypass kit and your boiler's manual.

Step 1: Safety First - Shut Down the System: Before you even think about touching anything, switch off the power to your boiler at the mains. Close the gas supply valve to the boiler (if applicable). This ensures that the system is completely inert and reduces the risk of electrical shock or gas leaks. This is the single most important step.

Step 2: Drain the System: You'll need to drain the water from the heating system. Locate the drain valve, typically at the lowest point of your system (often near the boiler or a radiator). Attach a hose to the drain valve and direct it to a suitable drain. Open the valve and let the water drain completely. This is essential to prevent water from gushing out when you disconnect pipes. Ensure the water pressure is fully released, giving you a safe and dry working environment. If you're unsure where your drain valve is, consult your boiler's manual.

Step 3: Identify the Components: Familiarize yourself with the components you will be working with. Generally, the bypass kit connects to the flow and return pipes of the heating system, usually near the pump or the zone valves. Identify the flow and return pipes to the faulty component that you are trying to bypass. The flow pipe supplies hot water from the boiler, while the return pipe carries the cooled water back to the boiler. Ensure that you have a clear understanding of the existing piping layout before you begin.

Step 4: Disconnect the Pipes: Carefully disconnect the pipes leading to the component that you are bypassing. Use your wrench set to loosen the fittings. Be prepared for a small amount of residual water to escape, even after draining the system. Have your bucket and rags ready to catch it. Once the pipes are disconnected, set them aside, ensuring you keep the fittings for later use, if possible.

Step 5: Install the Bypass Kit: This is where you’ll connect the bypass kit. Follow the kit's instructions carefully. The installation method will vary depending on the kit type and your system's piping. Generally, it will involve cutting and connecting pipes, using fittings to secure the bypass circuit. In some cases, soldering may be required if you have copper pipes. Ensure you create a secure connection to the flow and return pipes. Make sure all connections are tight and leak-proof.

Step 6: Connect the Bypass Kit to the Existing System: Once the bypass kit is assembled, connect it to the flow and return pipes. Use the appropriate fittings and Teflon tape to ensure a watertight seal. Double-check all connections to make sure they are secure and properly aligned. This step is critical because any leaks here will be detrimental to the system and could cause water damage.

Step 7: Re-Fill and Bleed the System: Once the bypass kit is installed, and all connections are tight, it's time to refill the heating system with water. Close the drain valve and slowly open the fill valve (if your system has one) or the main water supply valve. As the system fills, bleed the air from the radiators. Open the bleed valve on each radiator, one by one, until water starts to flow. This will remove any trapped air that could affect the system's performance. The pressure of the system should be within the boiler's recommended range, usually indicated on the pressure gauge. If the pressure is too low, the system may not work. If it's too high, it could damage the components.

Step 8: Final Checks and Testing: Once the system is refilled and bled, turn the power and gas supply back on. Carefully inspect all the connections for any leaks. Start the boiler and check if the heating system is circulating water properly. Listen for any unusual noises. Check the temperature of your radiators. If the heating system works as expected, then your IH Hewitt bypass kit installation is successful! Allow the system to run for a while, and re-check all connections for leaks after a few hours and make sure everything is working as it should.

Troubleshooting Common Issues

Even with the best instructions, you might encounter some troubleshooting issues during the installation. Don't worry, it's all part of the process. Here are some common problems and their solutions:

• Leaks: Leaks are the most common issue. If you spot a leak, immediately turn off the boiler and isolate the leaking area. Check that all fittings are tightly connected. If the leak is from a threaded connection, try tightening it further. If this doesn’t work, disassemble the connection, reapply Teflon tape, and reassemble it. If the leak is from a soldered joint, you may need to re-solder it. If the leak persists, consider calling a professional plumber.
• No Heat: If the radiators aren't heating up, check the system pressure. The boiler may not fire up if the pressure is too low. Bleed the radiators again to remove any trapped air. Ensure that the thermostat is set to the desired temperature and that the boiler is receiving a signal to turn on. If the problem persists, check the pump to make sure it is functioning correctly. If you have zone valves, ensure they are opening correctly.
• Air in the System: Trapped air can prevent proper heat circulation. Ensure that you have bled all the radiators properly. If you continue to hear gurgling noises, there may be air trapped in the system. Repeatedly bleeding the radiators can help. You might need to check your automatic air vents, if you have any. If the problem persists, a professional might be needed to identify the source of air ingress.
• Boiler Not Starting: This can have several causes. First, check that the power is on. Make sure the gas supply is on (if applicable) and that the gas valve is open. Check your thermostat settings and verify that the boiler is getting a signal to fire. Review the boiler's manual for any specific troubleshooting steps. If the boiler still doesn't start, there might be a more serious issue that requires a professional. Always prioritize safety and consult a professional if you're not sure about anything.
