My gutters are overflowing considerably when it rains. In particular, it is overflowing from one down pipe that goes into the ground into a charged system and into the rainwater tank. The water is then running over the gutters and down the brick wall and onto the ground next to the foundations which is not ideal in the long term. I have checked the gutters and down pipes for blockages and the mosquito net going into the tank an they are all clear however the flow into the tank seems very slow. The gutters are full and overflowing. I don't know how to make the flow into the tank quicker. I understand that our down pipes are continually full of water and as it rains the water is meant to push the water up the pipe and into the tank. Any advice would be appreciated.

MemberBest to check on two things ... 1) depending on the length of the charged downpipe, the gutter socket level should be at least 400 mm above the siphon level feeding the water tank ... 2) fine organic material builds up over time in the constantly full charged line regardless of gutter guard. These downpipe lines really need a screw cap 'scour' inspection opening in the low point of the charged line - this could be an 88 degree uPVC junction set in the charged line invert. The screw cap inspection pipe is set into the side of a precast pit which contains outflow drainage and goes directly into a street drainage system or absorption pit. During dry weather, you can unscrew the cap, drain the muck out and dispose of it, without ever having it siphon into your water tank.

The wet system should have been designed for a 1:20 ARI with an additional flow rate allowance for even heavier rain than a 1:2O ARI but it falls far short of this IF it is a new installation. If not, it may be goop in the wet system obstructing the flow.
1. Your post can be interpreted as saying that only one downpipe is plumbed to the wet system diverting water to the tank. How large is the total roof area harvested and how many downpipes are diverted to the wet system?
2. Is it a new installation?
3. What is the size and length of the wet system pipe?
4. Is there a flush outlet at the wet system's lowest point?
5. How much head is there measured to 40mm above the invert at the top of the wet system's vertical riser?

MemberHello can anyone help please? we need leaf guards on our gutters at our office (converted 1920s house in Geelong) under a plan tree. I remember seeing approx a million different ads for different guards - is there a clear winner? thanks Marilla

None of them are maintenance free.
Look for something flat that has larger holes and removable sections for maintenance access.
About 15 years ago I made the mistake of having a highly publicised brand fitted to one of my houses and it was a big mistake. It was flat plastic with small holes and it was fixed to the gutter's top outside roll by having the plastic siliconed to the roll and a metal strip then attached with screws drilled through the plastic into the gutter. Because of the small holes, the gutter had no ventilation for drying and the gutter's cross sectional flushing during heavy rain was severely disrupted due to the normal fall of water being dispersed by the small holes. This in turn promoted a build up of sediment. Working from a ladder to remove the metal rail and the plastic barrier was dangerous work.
