So it looks like I have damaged our drain field pipe with my ride on mower - not sure when but I am the prime suspect for sure - took out a 1-2 meter stretch of it.
At the moment - even in this hot weather - we have a collection of boggy land where the field pipe goes too. This may or may not be due to the damage it has incurred.
I am struggling a tad to find out if there are replacement pipes or repair kits - is this because there are none? Based in in Rodney district - any recommendations or stockist your know of? Don't want to face a hefty prices replacement of the field pipes just yet.
I have repaired the pipes that drip the liquid for our system using the joiners, clamps and pipe for the home garden irrigation systems from the likes of Mitre10, Bunnings, etc. The pipe that takes it to the driplines is much larger, but if that is damaged the alkathene pipe and fittings for farm waterline from rural supplies stores should do the trick.
First off, what kind of pipe is it? If clay feild tiles, you may not be able to replace, but if a Novaflow, type you can certainly get sections of that which can be fitted to existing pipe line and has clips etc. You can buy it from Rural Direct as they make it, or, other outlets such as M10 will have it.
Clay pipe cut broken section with diamond blade on a grinder to make a clean end
You can buy rubber collars that step down to a plastic pipe at places like Humes, they do up with jubilee clips/hoseclips
Get a section of pvc pipe to fit the missing bit
Do the same other end - pour a jug of boiled water over the rubber fitting and wear gloves if you need more flexibility
The cheapskate way is to drop in more clay pipe sections to fit broken section and use tyre tube rubber wrapped around the join and tie it off with wire - I've seen that work as long as it doesn't get disturbed
Novaflo pipe just cut out the squished /destroyed section, lay a new section in at the same length. Cut 2 jointer pieces around 200mm long each and then cut them along the length of them so that they can open out in a C-shape
Spread the C shape over the join and get it lined up with the ridges on the two pipe sections to be joined
Secure with wide pvc tape and tiewire over each end of each joint section
Good luck and post pics if anything isn't working
Our overflow pipe is perforated. If yours is too, then getting a tight seal is not very important, except to avoid much more overflow in that spot. So if you want the area to be dry then replace that length with a pipe that is not perforated and does have good seals.
Depending on where you are in Rodney I would talk to Penny at Pumps and Plumbing in Kaiwaka. She is fantastic, really knows her stuff and is very reasonably priced.
