Hi guys,

Looking for advice on whether I need to replace water mains supply feed from meter to stop cock. I was doing some work under the floorboards and saw this green pipe, I assumed it was redundant at 1st as there have been lots of bits done and changed over the years. Further investigation however confirmed this is the mains feed ! To the untrained eye it doesn't look great but cost to replace is something i haven't budget for. It's the partially green wiggly pipe in the photos!! Andy advice welcome.

Thanks

Pete

I don't think it should be what looks like garden hose.
It should be blue poly pipe
 
An old copper main, looks like it’s suffered some sort of corrosion (probably the cement it’s sat on), my advice if you can upgrade, now would be the time, unless you can access at a later date?

You could run new blue plastic all the way from the pavement to your indoor stopcock, in 25mm or preferably 32mm. This is likely to give you much better flow, which you will apreciate if you ever have a combi boiler, or an unvented cylinder, or an electric shower. Use a full-bore stopcock and run at least a short piece of 22mm copper from it that your hot and cold supplies come off.

Don't forget to insulate the new one. You can push Armaflex over it as you lay it with no need to slit or join, there is a grade suitable for buried use (it is dearer than indoor lagging)

Your old copper pipe looks quite badly corroded. Maybe it will last for years more before leaking. But why take that risk?

p.s.
poly pipe is quite cheap, but be sure to pay for good quality full-bore valves.

Thanks for the quick replies and confirming my concerns. It's a 20 meter run to the meter which is set quite deep on the driveway so will need to get someone in. I thought it was a garden hose at first, shocked to discover it's the copper main and only 15mm. Pressure in the house is surprisingly good given the state of the feed.
