Hi
Has any one got information on track pipe volumes and discharge rates
Currently doing a 3 storey plot of flats with 3 flats per floor , I've been asking from day one on meter locations so we can run gas 1st fix to meter box , no M&E drawings .
Meters was agreed to go outside in a semi recessed box directly below boiler with external gas risers , Now the main contractor has said they don't want to see the gas risers and have agreed with the utility company to build a separate meter housing compartment to the front of the block from there we have been asked to run the supply in track pipe in the ground to the building into a riser cupboard were the water mains are ,
The problem this has caused now is the from meter to boiler is approximately 41 meters to the top floor flat
25 meters of trackpipe with 4 sweeping bends
16 meters in copper with 13 elbows which goes through AECV in the cupboard
My initial thoughts are we are going to be over the 0.035 installation volume to run a worcester 30 si compact as this needs 3.24m3/hr i think 28mm will have more than a 1mb drop from meter to appliance with the length of run and bends calculated,
Need to do the maths on it tonight when back
Been told they cant fit the meters internal in a riser cupboard as the door to that cupboard opens internally into the communal space , can any one clarify this ?, apparently the cupboards needs to be accessed from outside the building with an external door , this is not possible as it's in the middle of the building
Thanks for your help guys sorry for the long text
