We’ve got a leaky pipe, and it’s got previous form.
Let me explain. When our heating system was installed, years before we bought the house, some of the pipes were laid across other pipes. They began to rub, and eventually, after about a dozen years or so one of them (the main hot water feed from the tank) wore through. The leak was under the floor in my office, and the water appeared in our living room at about 10pm on New Years Eve, three years ago. Temporary repairs were made and the next day a proper repair was effected.
All was fine except for a slight drip and even this stopped once the joint settled in.
That is until we had the boiler replaced, and now one of the joints in the repair is leaking again. I suspect it’s because the hot water is now pumped instead of being gravity fed (more pressure). It’s an awkward spot and I can’t get any more leverage to tighten it without doing serious damage to the rest of the pipework. It loses one drop every 45 seconds or so. This one showed itself on December 29th. Just as well it didn’t start two days later or we would have returned home from Jan’s party to a rather damp carpet. I put a tray under the leak to see how quickly it filled and a day or so later there was only a wet stain to be seen.
And guess what. We were sitting minding our own business after lunch today when Marie thought she heard a sound coming from one of the radiators. The sort of “ping ping” sound you get as they heat up or cool down. Only the heating was off and it wasn’t “ping ping”. It was “drip drip”. So up came the carpet and floorboards in the office, and yes, the tray was full. It’s a funny thing but I was only saying to Marie yesterday that next weekend we’ll fix the paper on the ceiling where it was affected by the damp, and check the tray. So now we know we’ll need to check it about once every three or four weeks until it gets bored and seals itself.
I hate plumbing.
