So there has been some developments.
Last tuesday I flushed the tank out with a hose from the drain out point to outside, several times over (fresh water to the tank isolated), hot tap open to vent it, blasted with cold water when empty to clear any sediment at the bottom of the tank assuming this is the issue that has been suggested (On here and by my local plumber).
I closed the tank drain valve, and left the tank empty for several hours to watch for a pressure change on the boiler. It Dropped about 0.2 bar over the 5 hours in the afternoon to evening. Put this down to a natural loss from the system still cooling from the heating on in the morning, and the day/house getting cooler.
Hot bath water still wasnt clean but better, so continued with tank flushing the next day. Even tried a back flush but only at mains pressure. With the tanke empty, this time left a tub under the tank drain point, and left the drain valve open. My thoughts were if the coil was split, surely it would be pi$$ing out water into the empty tank. An hour passed, not a drip or the sound of one in the tank.
Next day hot water was clean, finally and end to this. Seemed it was just dirty water from after the nearby street water leak and sediment stirred from the bottom of the tank. We have all showered and our little one bathed in it twice. The central heating has been on and off throughout, but not as much as weather is getting milder. We still have a drip from our overflow pipe downstairs but myself and plumber put this down to the cold pressure relief valve not re-seating after I clicked it over (probably the first time in 20 years).
Anyway..... 5 days on, tonight run a bath and get this below
Pressure at the boiler was a little low at just less than 1 bar with heating off but hot water on. Opened the filling loop and it immediately jumped 0.5 bar.
So. All things considered. Is this still dirty mains water, sediment stirred after numberous tank drains. Or is it the coil.
Any help would really really be appreciated.
