Hi All
Wondering if anyone could please assist. I have a cold tank loft water fed system, with a Grundfos Alpha2 pump fitted next to the water cylinder. which is situated in the airing cupboard upstairs. The boiler is an old Glow worm Space Saver mk2 which seems to be in good working order which is downstairs in the kitchen.
We have been in the property for almost a year and can recall the heating playing up when we moved in and as far as I can remember only heating upstairs.
Although the pump gets quite noisy on speed 4, this seemed the best operating speed as anything less didn't seem to get the water round to the downstairs radiators.
A few weeks ago, realising we still had a problem with winter coming, I bled all the radiators but with not much luck. I have then tried my best to balance them which seemed to move the hot water to the downstairs radiator for a couple of days and all seemed fine although the 2 main lounge radiators were only warm.
Gradually it got worse, and the water pipes in the airing cupboard have been quite noisy, and the noise from the water cylinder in the airing cupboard sounded like water gradually filling up, then stop, then continue for another 3 times filling and stopping/cutting out. I removed the front from the Grundos unit to vent any air out. The water started trickling quite soon so am guessing not much air was inside? With the screw removed there is a good jet of water. I noticed that the lower gate valve had started to leak where it meets the motor (new gaskets required), and yes obviously the valve decided it would not shut off for me. I wanted to drain the water but am unsure if I am draining at the correct point as the Grundfos unit arrow is pointing UPWARDS. I have seen after searches that this may not be good.
Please see photos attached.
Sorry for all the overload info/waffle, but my main questions are:
1) Am I draining the correct pipe 22mm which enter the bottom of the cylinder
2) Will I be wasting my time installing the pump back where it was?
3) Any other advice would help loads as currently no heating on.
Many thanks in advance for reading!
Kind regards Ian
