old steel water pipe

[adrianfs1]

hi all not been on here for a long while, hope all are well,
can anyone advise me as to the best way to repair a corroded steel water pipe, i have already removed the corroded area of the pipe of which i believe is about 20mm outside diameter, now got to repair it, it is situated about 600mm down but in a farm yard with a lot of heavy machinery passing over it, is alkathene the preferred option bearing in mind the old steel pipe is rough on the surface but is still solid, or would you guys prefer to use compression fittings, all advice appreciated, speak later.

alkatheanes fine with plasoon fittings

it will be iron not steel!
best thing to do is replace the whole lot. probably not what you wanted to hear......but to prove a point if you just cut out the damaged section first with a view to making a repair, just look at the inside of the pipe, it will be full of crud and i mean full! its really disgusting and this is supplying your drinking water!!!

does`nt it need to be deeper 750-1350 or am i thinking about summat else?

 

[jack0]

most proberbly will be 3/4 iron, alkathene pipe and fitting brand new job is the only way forward

I agree with above I would take it back as far as poss and put in 25 mm blue pipe and 750 is a good depth to stop freezing

 

[PlumbBobBob]

750 minimum.

 

[Stephen@nic]

Yer between750 and1500 I think bur 750 mm min is recamened

Mains and service pipes should be at least 750mm beneath the ground to protect from frost damage, but no deeper than 1350mm for ease of access. Also if you are going to replace the lot, 25mm blue MDPE is the best choice (all new service pipes are made from it!)

Its 1/2" pipe and I would use a couple of these Georg Fischer Piping Systems Ltd. - PRIMOFIT with a section of new pipe in between and dont worry about 750mm deep if you just replace a section.
