Drainage Upgrade - Dee Why

Drainage Upgrade to house & granny flat

We just wrapped up a drainage upgrade at Dee Why. The old system connected to the granny flat was installed incorrectly, with sections separating and causing seepage, no fall causing constant paper blockages, the kitchen line was connected below the level of the gully water and the shower was lacking a trap, which meant that bathroom constantly smelled.

Our team excavated and exposed all existing lines, replaced and re-graded the drainage, and connected new pipes for the shower, kitchen, basin, and toilet. We installed a new overflow relief gully, linked it to the laundry tub and floor waste, and added and installed a trap for the granny flat shower.

It's World Ocean Day.  Time to remember the three P's rule when flushing toilets. (Pee, poo and paper only) And don't forget, "flushable" wipes are not really flushable. Let's keep it clean for generations to come.

Is that a yellow bath? No, it is not what it seems. That is us dye testing the bath to check first of all a leak from the waste, then for a leak around the top seal of the bath. And yes it did leak. See the yellow trail coming down the kitchen wall. #dyplumbers #deewhyplumbers  #balgowlah #leakingbath https://posts.gle/dGsbKr

What started as a smallish job to drain some ground water seepage from under a unit block has turned into a major job. We have found that the old clay pipe stormwater pipe is chockablock full of soil. This obviously hasn't been working for years and years and no doubt contributing to their rising damp issues. Every piece of stormwater pipe dug up revealed more and more dirt. Even the newish part was full. Looks like there is more digging to do. #dyplumbers #deewhyplumbers #manly #stormwater #blockedstormwater https://posts.gle/GVz651
