warped timber boards.<\/li>\n<\/ul>\nThese signs indicate there has been significant damage to the home’s foundations and you should seek advice from a professional builder or engineer before proceeding with repairs.<\/p>\n
What to do if you have got a leaking pipe under your house<\/h2>\n Once you’re sure there is a leak there are a few simple next steps to take.<\/p>\n
1. Establish the location of the leak<\/h3>\n The first step is to establish where the leak(s) are located. If you see or hear water in one particular section of your floor, you might be able to take an educated guess, but there is no guarantee the offending pipe will be located right beneath the wet patch you’ve noticed on your carpet. Water is notorious for pooling in empty or low-lying cavities so the actual break or crack could be some distance away. You won’t be popular if you assure your wife you can repair the pipe yourself and cut up the concrete in her new bathroom floor only to find the water’s coming from a leaking join two metres along the line.<\/p>\n
Finding the exact location of leaking pipes beneath a house slab usually requires the help of a professional with specialised listening devices, CCTV cameras and other leak detection equipment. To detect leaks in the small pipes that bring pressurised water to your home, the water is often turned off and air is pumped into the lines to force out the remaining water. This allows the plumber to listen for escaping air from the damaged pipe.<\/p>\n
2. Arm yourself with numerous quotes and information<\/h3>\n Once the presence and location of a leak have been confirmed, the next step is the repair. If the leak is outside the perimeter of the slab or near the edge, and you know a bit about basic DIY plumbing, you might be lucky enough to be able to reach and repair it yourself without too much trouble.<\/p>\n
But if the leak is deep under your house slab, you would be best advised to consider a professional repair to ensure the structural integrity and insurance cover of your home are not compromised. You should get a range of quotes from different types of pipe repairers, and you should ask each of them as many questions as possible so they can advise on the pros and cons of their particular repair strategy in relation to your particular job.<\/p>\n
Just like doctors, whilst all plumbers know the basics, they’re not all experts in all things plumbing. Some specialise in new builds, some in water supply systems, some focus on gas fitting or roofing and some deal in mechanical services. So if you need to repair drain pipes under your house slab, you need more than just an everyday, all-round plumber who might only deal with similar under-slab leaks a handful of times each year. You need to ensure you deal with tradespeople with established reputations as experts in things like pipe relining, drainage and pipe clearing under slabs.<\/p>\n
When you are talking to each of the people quoting the job, pick their brains about possible options. For example, if the tradesperson quoting is a specialist in CIPP relining methods, ask them whether a traditional excavation and replacement might work better for you, and if not why. This way you will get to hear all the potential negatives of each strategy, which will equip you to ask better questions and make a more informed final decision. Once you have all the information and options, you are ready to consider which repair strategy is best for you.<\/p>\n
3. Decide on the best repair strategy for your situation<\/h3>\n There is no \u00e2\u20ac\u02dcone-size-fits-all’ best option for repairing pipes under a slab. If you’ve got a holiday home at the beach you can hang out in for a month, for example, or if you were already considering a complete kitchen and bathroom make-over, then excavating and replacing all your water and sewer pipes might not be such a bad thing. Carefully consider everything you’ve learned, taking into account all the additional costs for things like temporary accommodation you might need, having to buy takeaway for two weeks or re-laying the expensive new floor tiles your wife is likely to pick out. And don’t forget to factor in less tangible elements, like the joy of living with your mother-in-law for a month. This way you will avoid any unpleasant surprises when you add up the total costs after the job is done.<\/p>\n
