Hi folks.

A friend wants a combi boiler installed in their new Bungalow, but their incoming main pressure/ flow isn't all that good. The house is quite old and is fed by a 3/4" iron main which is very old.

I recently knocked on the door of a few houses down the same street and asked what their pressure was like to gauge how good the main was in the road feeding the street.

Some houses set back from the road ~ 50 meters which are newer than the rest, can't say their age though, maybe last 20 years (!?) have fantastic pressure, too much I'm told.

Another person who's front door is but 4 meters from the road said the pressure wasn't brilliant, but another two who are just as close to the road said that their pressure/ flow was great.

Now I didn't go into their house myself and check with my own eyes, but if what they say is true, I'd be tempted to run a new main for the bungalow.

Is there any certain way to;

A: Find out if the main in the road is brilliant, worth teeing into as such. Can the water board tell me, do a test? I was thinking of picking the brain of a local water company who do new mains, see if they had any experience.

B: Find out if all of these houses are on the same main, I checked houses both sides of the bungalow, so I'd think they were. But I don't want to be dealing with two mains to find out they're on the bad one.

C: If I ran a new MDPE service pipe from the house to the street, I'm assuming that I'd have to get the water board out to tee it into the water main. Would winding the iron out of the water meter/ stopcock and winding the new service pipe in be fine, or would the water meter and stopcock act as too much of a restriction and be a waste of my time. I've not yet seen the meter/ stopcock, so they might be bushed down, but I doubt it.

My original thought was to leave some slack in it, tee it into the water meter and try it, if not great, get the water board out to tee it into the main.


Answers on a postcard.

Cheers.

If its an old iron supply pipe it has a limited life,if you do the digging your self it should keep the price down,when the new plastic service enters the building use a 22mm lever valve rather than a 15mm stopcock,this will increase the flowrate internally.
 
Talking to a water board man , he told me they are turning the mains down as this causes burst water mains to pop in the winter , combi,s will suffer soon will poor pressure & flow ..
 
It is an old 3/4 iron main. So you think that a new MDPE pipe may give the supply a new lease of life? I'm happy to dig the trench and lay the pipe/ connect it up. But what are the rules of thumb in regards to sizing a new main?
