pump

Hi all, our central heating water pump has started making a repeated clicking sound (you can hear it in this video clip https://tinyurl.com/trlcxxl for the first 10 seconds) sounds a bit like an electrical contact switching or a solenoid. This seems to happen before every time the gas boiler...

The pump in my system is behaving strangely. Normally it indicates that it is running at about 43W. Since Xmas morning, it has only been at about 18W. When it starts up, it goes up to 45 for a few seconds and then back down 3 or 4 times. Added to this, it worked perfectly for a time yesterday...

Hello all. Been babysitting an old Baxi105e for three years and it's not a disaster but a bit temperamental. Current niggle : first time in the day, the CH side only fires up if the Hot water is run at the tap first for a few minutes. On turning the hot tap off the CH smoothly takes over and...

Good Morning All, Im wondering if anyone may be able to help or advise please. I have an issue I believe is tied to a leak coming from the combi boiler (Biasi Riva Plus HE M296 28SMC, 2015 Model): Last night the RCD on my home electrical system consumer unit tripped, after much hunting...

we've got quite an old central heating system (regular boiler) with a tank in the loft. i could have sworn the water in this tank used to be hot, but i assume i'm mistaken and that it's a cold water tank? anyway, recently the heating has been making lots of creaking noises and the pump it's...

Could someone help me with the issue I have with my boiler please. When in Central heating mode the boiler will fire up for a few minutes but the pump runs constantly - even with the dial on the lowest setting. Is this a characteristic of this boiler or a fault? In my old house there was a...

Hello all, I'm at my wits end... I have fairly recently taken the plunge and re fitted my entire bathroom. I should probably add at this point that I am not a plumber and before I undertook this mammoth task I had no plumbing experience whatsoever. I hope that this has not now let me down at...

Hello, I have a problem with my Worcester Greenstar 42cdi. It was working fine until yesterday. when I noticed that the hot water would not get hot. upon further investigation, I am even more baffled. The boiler is in the upstairs bathroom. 1. Bathroom sink, (closest to boiler) gives warm...

Hi. I've got quite a useful loft space that makes quite a good workshop. The problem is that as most lofts do, it gets very hot up there in the summer time. The roof is not insulated which I'm sure would make a big difference however I can't afford to do that. I'm thinking about whether I could...

Hello all, I may have to get my central heating pump changed as it is making an almighty rattle all the time* but I am not sure which one to get. The pump I have currently got is labelled 'Grundfos Selectric 4', Type 4 -50/130 (please see pictures attached) and has 4 speed settings. Is there an...

Hello Looking for a bit of advise before next step. Moved in earlier this year. House is 4 bed, 1 bathroom 2 ensuites. Extension has 1 of the ensuites which has a shower pump lovating in the loft above. I’ve attached a basic,but hopefully clea, diagram of how the shower/pump is plumbed in...

Pump runs, hot water going into central heating pipe, first 3 rads getting hot water but last 3 rads warm at the inlet but rads cold. Hot water is working ok. when the heating is on pump is running but only about an eighth of a bar increase in pressure. I'm thinking that there is not enough...

Hi all, After a bit if advice if poss. I have an old open vent system in my house, and from a fair old bit of investigation I definitely think the pump is in the wrong place. It's straight after the boiler on the flow side, before the open vent. From my workings it looks like it should be...

Hi all, So, basically I have a h/w combi cylinder that isn't giving me quite enough flow in my flat and I want to put a pump in. Bath takes an hour to fill (electric shower is used instead) even the kitchen sink and the basin give 2 l/m which is just useless. I've been thinking about pumps and...

Background I have a Grant Vortex 36E Oil fired boiler. Two Grundfos pumps inside; one for the rads & one for the hot water. The Problem The pump on the hot water circuit is making a howling noise when I run hot water. But not always. The hot water pump has, and as far as I know, always has been...

Hello, I have a situation that may resonate, I think there could be two faults: Situation: excessive oil being used in heating/hotwater system, pump never turns off, radiators often hot even when programme is set to off/off. There is a drayton motorised valve on a Y valve Often one can hear...

Hello All Can someone shead some light on my central heating please. The pump comes on for a bit after the heating goes off, here's what happens. I have a standard boiler pumped with HW tank, with a room thermostat for the CH also a programmer When the room thermostat calls for heat the pump...

I have a long standing problem with inadequate flow to radiators. Despite all my efforts at balancing them only about half of them can be fed at the same time, while the others remain cold. I've tried flushing the system, and in some cases removing rads and hosing them through, but can't find...

Hi, I have a Worcester Bosch Greenstar 18Ri regular boiler installed within my garage. There is also a Honeywell T4360 Frost Thermostat installed just above and to the left of the boiler. The problem I was having was that the Frost Thermostat was kicking in in cold weather and firing up the...

My mum has a Miele Novotronic Premiere Plus, purchased around 1997. Recently, it started to leak during cycles, but was still able to wash clothes. We pulled it out to have a look at the pump (where problems have arisen previously) and now it is leaking far worse. Currently, as soon as we...
