main water inlet

[darlo1971]

hi, i really need advice, we have a black plastic cold water inlet pipe coming through the concrete under our kitchen sink. there is water seeping up through the concrete, this is beyond me can anybody help.

Are you sure its seeping up & not running down from the stop tap. Possible slight leak around compression nuts or packing gland!

 

[darlo1971]

hi no its definately coming up my hubby saw it come up and the black pipe is bone dry

 

[Puddle]

in that case you seem to have a split /damaged plastic water main,probably not protected correctly

You need to get a plumber in and maybe one of these

HSS Hire - Vibration-Damped Breaker Hire and Rent

hi puddle ty do you know roughly cost wise what a plumber would charge for this ty for the link as well

Keep an eye on it & see if it gets worse, could of been a drop of condensation ran down the pipe. Looking at the wet patch around the bottom of the pipe really looks like water has ran down it. If it spreads & gets bigger & the pipe is 100% dry, its time to start digging!

Why is it black? Sleeving?

Excuse my infinite dumbness

 

[darlo1971]

hi i dont know why its black.....it was black when we moved in 8 year ago ive heard it should be green

 

[Spike295]

Incoming cold mains were black poly years ago.

 

[Spike295]

Green is the writing that could of been on it, this told what class of pipe it was.

 

[WaterTight]

Can you join onto those with current mdpe fittings?

If it's not condensation as stated above, turn off your outside stop tap and start digging. Expose the pipe, turn on the stop tap a little to identify hole, turn off, cut out hole and take the bit to plumbers merchants for correct size philmac connector and inserts.

 

[Spike295]

If it does resort to having to dig it out & you decide to do this yourselves, first make sure your outside stop tap is working, then start digging with the water still turned on. You'll know where the leak is as soon as you get to it, then turn off the water & deal with it from there.

Plus if you accidentally dig to hard you get a free water-park!

 

[Spike295]

Your gonna have to be pretty clumbsy to go thru a poly pipe you can see!

 

[WaterTight]

Still though I'm the nervous type. I'd go back and forth turning it off and on now and then.

 

[Spike295]

Live on the edge a little...i dare you...lol

They gotta be worth their weight in gold. So handy for exactly that, stopping dust entering an open end when drilling above or for feeding a length of pipe under floors. A million uses for these things.
