Re: Weep holes on ground level after outdoor tiling 16Jul 14, 2021 1:07 pm Thamz We just did a major renovation and went with the builder. Unfortunately we agreed to the tiling without doing our homework. I wrongly assumed that it was a new house. I should have asked. If it wasn't going to be compliant, they should have explained why and not done the work or else looked for an alternative. Is there any slope on the tiling? Thamz The gutter overflowed once in March during the flood in NSW - havent seen it overflow since then. We are in north shore. You are not in a low rainfall intensity area. The 'under cover' regulations are vague because there is no formula that factors applicable widths and heights for wind driven rain but the minimum 50mm gap under cover regulation is set in stone. Eaves gutter compliance needs only to be applicable to a bare minimum 1:20 ARI. The storm you experienced possibly/probably qualified as a 1:20 ARI. Thamz We are in the process of adding an extra downpipe and enlarging the storm water pipes. For now that's the best way we can think of to safeguard from water from touching those walls. We dont have the budget to do anything else. we may consider knock down and rebuild in 5 years time but till then we need to do the best we can. Was the overflowing water isolated to one area? Downpipes are installed in an elongated W pattern, the low points (bottom of the gutter's slope) being where the downpipes are fitted and the gutter slope's high points determining the roof areas that drain to each downpipe. If you fit an extra downpipe, it will be fitted between a downpipe and one of the two high points that service that downpipe. If a gutter overflows on both side of a high point, one downpipe won't do the trick. Digging up and replacing stormwater pipes with larger pipes is an expensive undertaking. For minimal cost, you could simply buy a small rainwater tank of about 1,200 L (good condition used ones come up all the time on GumTree) and plumb one or two of our Gutter Pumpers to the gutter to divert excess water during heavy rain from overflow areas to the tank. This way, the downpipes are not altered and the cost savings would be considerable. A small outlet valve fitted to the bottom of the tank would then divert a limited discharge flow rate through a small pipe (poly or similar) to the stormwater system, usually to the bottom of the downpipe. This is called a detention system. The tank's bottom outlet valve would have the tank immediately draining plus it will drain faster as the tank fills due to the increasing hydraulic head. The above doesn't fix the weep hole issue but it will prevent overflows and is quick and easy to do. As for the weep holes, well...the work is not compliant. 3in1 Supadiverta.
