Laying new water supply pipework

[Madrab]

I'd leave well alone, just make sure your backfill is consolidated correctly, so they cant blame you for undermining the pavement

Can't get any better advise than that IMO -

You can call the Water Co and suggest that you have observed a few older people being caught out by the dip and losing their balance a little, they'll be out in a jiffy.

Ok so make the connection then pack the undermined area below the pavement with Type 1. Backfill my trench then call Thames Water out in a month or 2 to make good their meter box that has sunk.

I would contact Thames Water now and mention you have a lead supply pipe that you are replacing with plastic and that their meter chamber is a potential hazard to the public.

They may then come to site to do what is necessary to re-instate the meter chamber to remove the public hazard and while on site connect your new service pipe to the meter.

Leave the trench open so Thames Water can see if there are any problems and / or they decide to lift the meter chamber.

If the meter chamber has sunk and their pipe to the meter is under strain then they may lift the meter.

If your new pipe is connected by you to the meter and the trench back filled then when the meter is lifted the joint between meter and you pipe ( bedded in back fill ) may be strained.

Is it ok to leave the lead in the ground rather than remove it once dissconnected

Yes, no problem.

The trench may be open a loooong time by the time the water people come along.

hence the reporting of the potential hazard to members of the public

If the lead is exposed in your trench you should really go and weigh it in, for the environment, not the cash you will get

Only the end is exposed currently. It looks like it runs under my drain line which will be dug up in the future so i will do my bit for the environment when that gets dug up.

 

[padstar]

I plan to run a water point to the back of my garden in the future. Is it best to T off the new pipe i am laying in the drive now and cap it rather than T into it at a later date? Assume 25mm is ok for this

Or is it best to split after the internal stop cock and then loop back underground?

 

[hard-work]

Depending on space, you might want to put the tee inside the house, to avoid a joint under the ground. So, 32mm into the house, a tee, then 25mm out back under the ground to the back garden. Put a stoptap on the 25mm inside the house.

 

[padstar]

I did think that after posting the original thread. I will bring the 32mm into the garage and then reroute the external tap from the internal pipework out when re plumbed. I don't want to be digging up the drive again due to a failed joint at a latter date.

 

[hard-work]

Yes, think ahead in case matters go wrong. Also, have the garden side with an isolator tap, so if problems it can be cut off with the house not affected.

So I got the water feed connected today with a temp connection to the internal pipework until the house is re plumbed. I was quite surprised that the connection to the meter was barely hand tight i cranked my connection up a bit. I am going to leave it over night to check its all dry in the morning before i back fill.

It would have been a good end to the day turning the water back on but i now have an air block inside that i cant shift meaning we have cold water upstairs but nothing down stairs. Any ideas on how to shift it? I have held the kitchen tap closed and shot hot water up the cold via the kitchen mixer which got the downstairs WC and basin flowing (with hot water) but when i release the kitchen tap it just drains out and then left with noting.

You ignored my advice. Putting it in a soil pipe as a duct is a cowboy approach. You shouldn't have done that and I can't think why you would think that is the way to go.
