Moving boiler water pipes advice ?

[ThAA]

Hi All

I am currently converting my garage into a playroom for my Mrs and her childminding kids. To create a doorway to the kitchen I need to raise 2 water pipes, the Feed and return pipes to the boiler. The boiler is an old Potterton Flamingo 50s gas unit which hasnt missed a beat. The system I beleive is a vented system. My intention is to drain the system and raise the pipes as shown in the below diagram. Before I do this I have noticed thet the current pipework is generally heading downwards towards the boiler and is seperated by some distance over the length of the 2.5M wall. I intend to raise these pipes and site them next to each other.

Is my intended change going to effect the flow of the water causing problems or am I being worried over nothing?

Black dotted line indicated existing pipework
Red dotted line indicates intended new position.

Cheers in advance

your new pipeworkwork will cause air to get trapped in the top as your going up from the boiler and back down the other end,

I thought as much

Is there a way of removing the air if it gets trapped and will I continually be battling to get rid of it or will it disapear for good once I have removed it ?

How can I get round this? any suggestions ?

can you not take them across at an angle to rejoin the others abit higher

Would any of these suggestions be OK

Yep the top one is the only way but it means cutting though a load of bricks, and ripping up floor boards to get to the hot water tank.

Time to call in a plumber me thinks!

Many thanks for your help

I would of thought the second option would be OK as one of the existing pipes is above the proposed new door, and would be less work

If the pipes are not right up against ceiling then a thumb screw air vent could be used.

If there is a room above the garage with floorboards then a pipe could be taken up and have a thumb air vent above the ceiling but under the floor.

It might just work but I have to put in a lintle so both the pipes would be in the way and could get damaged.

You mean like the ones on a radiator?

Would I have to release the air just the once after installation or would I expect to see a regular build up of air in the pipes?
