Discovering a leak in your home is stressful at the best of times. When that leak comes from faulty Tectite fittings hidden behind walls or under floors, the damage can be extensive and the repair costs substantial. If you’re dealing with water damage from leaking Tectite plumbing fittings, you’re not alone. Thousands of Irish homeowners have faced this exact problem, and many have been able to recover the full cost of repairs through their insurance or directly from the manufacturer.
This guide explains what Tectite fittings are, why they fail, and how to approach a water damage insurance claim. We’ll also look at when you might have a claim against the manufacturer and how a loss assessor can help you through the process.
What Are Tectite Fittings?

Tectite fittings are a type of push-fit plumbing fitting used to connect copper and PEX pipes. They became extremely popular in Irish construction from the early 2000s onwards because they’re quick to install. A plumber can simply push the pipe into the fitting to create a watertight seal, without needing to solder the joint or use compression fittings.
According to Excel Industries, the manufacturer: “Tectite fittings simply push together in seconds to create a perfect joint. The heat-free principle of the jointing process is one of the major benefits of the Tectite system, resulting in an uncontaminated installation fitted in a fraction of the time taken using other jointing techniques.”
The fittings work using an internal O-ring seal and a grab ring mechanism. When you push a pipe into the fitting, the grab ring grips the pipe while the O-ring creates the seal. This design allows for rapid installation, which is why builders and plumbers adopted them so widely. Tectite fittings are available in Irish sizes (1/2″, 3/4″ and 1″) and can be used with copper pipe, PEX, and other plastic pipe materials.
Where You’ll Find Tectite Fittings in Your Home
Tectite plumbing fittings are commonly found throughout modern Irish housing stock, used in both housing schemes and one-off dwellings. The problem for homeowners is that these fittings are often concealed in areas that are difficult to access and inspect
Common locations include under floors and floor coverings, behind plaster walls and tiles, within ceiling voids, in attic spaces near water tanks, and throughout central heating systems. This hidden installation means a leak can go undetected for some time, causing significant water damage before you even notice there’s a problem.
Why Do Tectite Fittings Leak?

There are several reasons why Tectite fittings can fail and cause water damage. Understanding the cause is important because it affects whether you claim through your home insurance or pursue the manufacturer directly.
Defective Manufacturing Batches
A significant number of Tectite fittings distributed to the Irish market were found to be defective. The O-ring seals contained within these faulty fittings deteriorate over time, causing them to leak. This manufacturing defect has affected thousands of Irish homes, and the manufacturer has admitted liability in many cases.
If your home was plumbed with fittings from one of the defective batches, you may be able to recover the full cost of replacing the faulty Tectite fittings, re-plumbing the entire property, and repairing all the resultant water damage directly from the manufacturer’s insurers.
Improper Installation
Even with properly manufactured fittings, installation problems can cause leaks. The pipe must be cut cleanly using a pipe cutter, not a hacksaw. The cut end needs to be properly deburred and chamfered to avoid damaging the O-ring seal when inserting the pipe. If the pipe isn’t pushed fully into the fitting, or if there’s dirt or debris on the pipe surface, the seal may not form correctly.
Silicone grease is sometimes applied to help insertion, but using the wrong type can damage the seal over time. These installation errors may not cause immediate leaks but can lead to fittings leaking years later.
Seal Degradation and Environmental Factors
All rubber seals degrade over time. The O-ring in a Tectite fitting can deteriorate due to age, water chemistry, or exposure to incompatible chemicals. Freezing temperatures can also damage both the fittings and the pipes themselves, causing catastrophic failures. Storm damage or pressure surges in the water supply can stress fittings that were already compromised.
Signs of Leaking Tectite Fittings

Because Tectite fittings are usually hidden from view, you need to watch for indirect signs of a leak. Early detection can significantly reduce the extent of water damage.
Warning signs to look out for include water stains appearing on ceilings, walls, or floors, a musty smell in certain areas of your home, unexplained increases in your water bill, reduced water pressure, visible damp patches, peeling paint or wallpaper, and a loss of pressure in your heating system. If you notice any of these signs, it’s worth investigating further. A pressure test on your plumbing system can help identify whether you have a leak.
Filing a Water Damage Insurance Claim
If you have water damage from leaking pipes or fittings, your home insurance may cover the cost of repairs to ceilings, floors, walls, and other affected areas. The extent of your cover depends on your policy wording, so it’s important to check what’s included.
When making a water damage insurance claim, you should document everything with photos and videos before any cleanup or repair work begins. Contact your insurer to report the damage and get a claim number. Keep a record of all communications. Save receipts for any emergency repairs or accommodation costs. Don’t throw away damaged items until your insurer has assessed the claim.
Be aware that many standard policies cover the damage caused by the leak (the water damage to your ceilings, floors, and belongings) but may not cover the cost of finding the leak or replacing the faulty fittings themselves. This is where a claim against the manufacturer may be relevant.
Claims Against the Manufacturer for Faulty Tectite Fittings
Where the leak is caused by faulty Tectite fittings from a defective manufacturing batch, you may be able to claim directly from the manufacturer’s insurers. This type of claim can potentially cover the cost of replacing all the faulty fittings in your property, re-plumbing the entire home to remove defective fittings, and repairing all the resultant damage to ceilings, floors, walls, and finishes.
The costs involved can run into tens of thousands of euro. In many cases, ceilings, floors, and walls need to be removed just to access the concealed fittings. The damaged flooring, tiling, ceilings, and wall plaster then need to be reinstated once the plumbing replacement is complete.
Insurance Claim Solutions has represented a large number of homeowners who have had water damage as a result of the catastrophic failure of these Tectite fittings. We have been successful in recovering the full costs from the manufacturer’s insurers, including the cost of all repairs to the property.
How a Loss Assessor Can Help

Dealing with a water damage insurance claim can be complicated, particularly when there are questions about whether the damage is covered, whether the manufacturer is liable, or how much the repairs should cost. A loss assessor works on your behalf to help navigate the claims process.
While a loss adjuster is appointed by the insurance company to assess the claim on their behalf, a loss assessor represents the homeowner. They can help by assessing the full extent of the water damage, including areas that may not be immediately visible. They review your policy to understand what’s covered and identify whether you may have a separate claim against the manufacturer. They prepare and present your claim documentation, handle communications with the insurer, and negotiate on your behalf to work toward a fair settlement.
For complex claims involving faulty plumbing fittings, professional assistance can be particularly valuable. The claims process can involve technical questions about what caused the leak, what repairs are necessary, and who should pay for them.
Preventing Future Problems
If you’re concerned about Tectite fittings in your home, there are some steps you can take. Have a plumber carry out a pressure test on your plumbing system to check for any existing leaks. Periodically inspect any exposed fittings for signs of corrosion or dripping. Make sure pipes in unheated areas are properly insulated against freezing. If you’re carrying out renovations, consider whether to replace concealed fittings while you have access.
Some homeowners who have experienced problems choose to have their entire property re-plumbed to remove all Tectite fittings, replacing them with traditional soldered joints or compression fittings. While this is a significant investment, it can provide peace of mind and may be worthwhile if your home contains fittings from a known defective batch.
What To Do If You Have Water Damage from Tectite Fittings
If you’ve discovered water damage in your home and suspect faulty Tectite fittings are the cause, the first step is to document the damage thoroughly with photos and videos. Contact a plumber to assess the situation, identify the source of the leak, and carry out any necessary emergency repairs to prevent further damage.
