Original Lead pipes are still being used to direct water into homes. However, extensive research has it documented that lead is a dangerous component once it gets into human body. In addition, the water pressure is pathetic with this original pipes, in some cases no pressure at all. That stated, it implies that that water main replacement has to be carried out. However, what about the estimated costs of water main replacement? Sampled quotes for the work approximates to around £600, really expensive. Readers of this article will be able to equip themselves with the ultimate steps of replacing their lead pipes themselves. Basically they will need;
Graft spade, this is a basic spade that is about half width of the normal spade (very slim) and long. This will save users energy to be able to dig a lot and will save time by digging faster.
25mm plastic pipe, this pipe should be blue. This pipe is used for normal underground conditions
Stop tap, most people still have their taps that they can use but it is likely going to wear out faster than the newly replaced system or it is already leaking. Since the user also has decided to go plastic, a plastic stop tap will be great.
Ducting and insulation, any pipe can do insulation. For the ducting users can still used the old underground lying ducting provided it is 100mm diameter.
He/she will need builders sand, 3 sealing’s at both duct ends, connectors and a decent weather.
Procedure on how to
Dig narrow trench from the garden wall to the front of the house with minimum depth of 750mm. this will keep the pipes safe from frost. The pipe needs to be 350 mm away from other service pipes. Check all the location of gas pipes, TV, electricity and network cable pipes. Now the digging can proceed to into the house after the outside id done. Make the existing hole larger in case there is a missing brick.
From here, push a ducting through the opening, leave the existing supply next to it, and then use normal foam fillers to fill the gaps left around the ducting. Take care not to get the filler into the pipes. You can now lay the new supply pipes up to the edge of your property boundary. If the digging gets to the outside of your wall into the pavement, then it should be very tiny so that the refilling costs do not go higher. Here it is minimizing costs.
Before putting the pipes into the trench, liming should be done by pouring some sand into the trench; this will protect the pipes from injury and damage. Lay the pipes starting from pavements if any and then push them into the wall. Here is where the job gets a bit fiddly but the afterward pushing of pipes is easy. The pipe both ends must be sealed during pushing to ensure no foreign particles gets into them.
Where the pipe enters the building should be insulated. In addition, a pipe about one meter should be left outside where it will connect to the water main supply. The utility company will come inspect and sign the work done. If it is per standards, the trench if filled and your pipe will be connected to the mains and there goes a replaced water piping system.
