    Hi I am thinking of modifying the pipework to my Baxi 24 solo he. At the moment the feed and return both point upwards. I intend to feed the return from the bottom, so I will need a vent on the return, any suggestions of the best way to go about it. I am thinking of removing the supplied return pipe from the boiler, fit a tee 28 or 22 mm then bring the return into the bottom of the tee, connect a 15 mm vent via a reducer to the top. What vent/ parts would you recommend . All recommendations appreciated. You may aske why modify it the Magna clean is under the floor boards at the moment, and this is the only way I can fit it above in a more serviceable position.
