    Changed radiator now F&E Tank is overflowing

    I thought this one through... I bunged the system rather than draining it, and in doing so, nudged the float valve thereby raising the water level. I couldn't say 100% that the float valve wasn't contributing as it was a mess, so I changed it to be on the safe side. But certainly the main...

    Changed radiator now F&E Tank is overflowing

    Not reluctance, just time! I had to wait until Saturday because of long working hours Mon-Fri. I don't mind the loft space, I replaced a couple of seized isolation valves while I was up there with my gear so all in all, a pretty productive weekend.

    Changed radiator now F&E Tank is overflowing

    An update, an inspection of the F&E tank revealed the water level was way too high, just below the overflow at fully cold. So I drained and cleaned the tank, fitted a new float valve and reset the level. No water leaking out the overflow for the last two days. Re the pump, this is where it is...

    Changed radiator now F&E Tank is overflowing

    None of the LEDs flash, they are constantly on. I checked and it is definitely PP1. The house felt a little chilly this morning. I have increased the pump setting from I to II and will see how that feels when the heating comes back on later. At PP1, should II be sufficient or should it be set...

    Ok, I will adjust the setting, thank you for that useful information. TBH the installer messed up a few things so no huge surprise if the configuration wasn't right. It is not set to PP2 btw, it looks like PP1 from the diagram, green space space yellow. Really appreciate you looking at this.

    Changed radiator now F&E Tank is overflowing

    The heating was on for one hour before the water came out. There are 14 rads and it's a fairly big place so that feels to me like it would be down to the water level being too high and the expansion reaching a critical point and driving the level above the overflow. But just guessing until I...

    Changed radiator now F&E Tank is overflowing

    My job for tomorrow is to go into the loft and investigate the depth. I wondered if I could have somehow knocked the ballcock when putting in the bung but there's no constant drip, just a spurt when the heating comes on. I will check and lower the level if it's too high. I've just put the...

    Thanks for the response! Oil boiler, Worcester Bosch, 4 years old, regularly serviced. Last serviced end of January. Internal circulation pump located in the airing cupboard, also changed 4 years ago. No adjustments made to anything else, other than changing the valves and draining/refilling...

    Changed radiator now F&E Tank is overflowing

    Hi there, I had to remove and drain a towel radiator a few weeks ago as both valves were leaking and needed replacing. I bunged the system rather than draining it because it's a big house and the refill process takes hours. The water that drained from the radiator contained some black sludge...
