hi
i've had a read of the faq and i think i know what to do but would appreciate someone with a bit more knowledge checking if poss
changing a radiator and moving it about 6 inches to the left. its plastic speedfit type 15mm pipe and its coming from the left so all i'll have to do is remove some plaster board and trim the pipe back to the new length needed.
i have a pressurised system with the boiler downstairs in the kitchen and a cylinder and pressure vessel upstairs in a cupboard.
so the plan is:-
turn off the boiler
attach a hose to the drain point on the radiator downstairs
once its drained for 15 mins go upstairs and crack a bleed or 2 off on the rads up there.
once its fully drained remove old rad.
dress new rad
fettle the pipework and get the new rad secured in new positon.
now this is the part i'm not too sure on
above the cylinder there are 2 pv's one red with a gauge on the base as i've seen in the faqs, and another white one which looks pretty similar to the red one, apart from no gauge. then there a braided pipe linking the two, with valves at either end which are shut. from what i can gather opening the taps starts to pressurise the pv.
so i'm assuming once i'm happy the rad and pipework etc is good to go, is it just a case of opening the valves on the braided hose to begin refilling the system, then bleed the rads, then turn the boiler back on?
or do i have to pressurise the system using a handpump as per the faq's
also can i just pour the inhibitor into the new rad before i seal it? and i've seen that flushing the system is advised, is that necessary after changing 1 rad?
many thanks for your time.
