Thread: Finding Wet system leak?

I wonder if your shack may be the same.

Edit: I just re-read your post and your comments about a T where the two building feeds meet. My comments don't apply, unless the T is actually where the feeds from two sides of the house meet?

Unfortunately no drainage plans
Definitely a line running from shack to house
Raining now so waiting for a dry few days to continue my archeological dig

It is completely rooted and leaking like a siv with a bit of a bog hole under it once I dug a bit deeper. Definitley a part of the problem but not all.
I bodgied it up to catch a bit of forecast rain tonight and we had a quick few mm.
The bodgied repair held up ok and I was surprise how quickly the water arrrived at the tank.
Also surprise how long it kept trickling in after the rain stopped.
While it was trickling in I checked all the house down pipes - all full or at least higher than the tank inlet as you would expect. This is good.
But the down pipes at the shack were empty.
I cleaned al the gutters out yesterday so I know they are working ok.
So the water from the shack is running away to where...certainly not getting to the T junction.
So that line must be leaking on the shack side of the problem and blocked on the house side of the problem.
That leaves about 30 metres of pipe where the problem could be.
So the plan is to
1 replace the T junction
2 cap the shack line near the junction
3 stick something down the exposed line to see how far down the blockage is

I think my logic is sound?

I have replaced the t junction and the house system is now water tight..v happy about that..water level now holding right at tank inlet level after some rain.

Shack down pipes remain empty....work to do to work out why but not today.
