Hi,
I am a keen DIYer so please be kind. I have done my best.
Have an issue with what I think is airlock and need some help please.
My system in my modern 2012 home comprises a megaflo cylinder for mains pressure hot water, condensing boiler and no loft tanks.
Earlier in the week I replaced the kitchen mixer tap as the old one was leaking from the body. As usual cut off the water at mains cold and at the hot tank. But also drained the tank and reset the air gap as I have a few times in the past. Swapped the tap no worries and all is well there.
Ran all the taps one by one, let them do their spitting carry on. All well.
Day later realised the bath upstairs was running slow on the cold side. We've had issues with the tap valves, so turned off the mains cold again and swapped out the valve. Things seemed much improved.
Today notice the sink and toilet are slow in the same bathroom. Presume airlock, but as I had some spare tap valves, replaced that using isolator on line under the basin. No improvement in flow.
Bath excellent in that room, as is shower. All hots ok. Just sink cold and toilet which is next to it slow.
Figured air lock, so tried the hose on to another tap trick a few times. Nothing, well other than me getting a bit soaked. Still trickling.
Took toilet's siamp style fill valve apart in toilet to check it. Removed the diaphragm and ran the water. Flow there was tiny with tap on, little more of a flow with it off. Rubber diaphragm ok. Toilet does still fill though, albeit quite slowly. Put it back together.
Also tried attaching the water hose from a working tap to the open toilet valve and blowing it back to attempt clear airlock. No change.
Tried turning cold water off again. Opening all taps a bit. Water back on. Open the taps wide in sequence up to the trouble one. No change.
I don't want to apply too much more reverse pressure, as the house has a pipe organ of plastic push fits in the void which I would have a mare on my hands if one blew off. Mind you I did get brave and go for it a bit with the hose trick. Still nowt.
What might be going on and do I have a hope of solving it. Considered and more experienced help very much welcomed.
Thank you
