Hello, I had to remove the inlet end of my booster pump to get a new non-return valve fitted - but now I can't get it back on! It doesn't quite push far enough into place to allow me to get the three screws back in to fix it on. I've looked at the Grundfos servicing video on Youtube but...

My oil boiler started locking out intermittently a while ago but would always run again after the reset (orange lit soft plastic) button was pressed. It gradually got worse - locking out more frequently - but would always fire up again with a reset. We had the boiler serviced by an unknown...

Hi all, Just had to replace both Potterton two-port MVs and Grundfos circulating pump in my quite old indirect system and while the central heating side of things is working, the hot water valve is not coming on at all when switched on at the programmer. The little orange light on top is not...

Hi all, The saga of my Grundfos MQ 3-45 continues. Having sorted how and where to put the non-return valve (see previous post) the pump now won't stop running, even when there's nothing pulling water. The instructions say it will do this if there's no non-return valve or it's faulty or...

Hi, I'm installing a new Grundfos MQ 3-45 water pressure booster pump and have got fittings to take the 15mm supply on to the 1" inlet port (and the other way round for the output). I need to fit the non-return valve (supplied) into the inlet port but the 1" female end of the fitting does not...

Hi all, my Grundfos Jetpaq water pressure booster pump went pop yesterday, tripping out the RCD in the fusebox. I checked the fuse in the fused power socket and it's fine so must be in the beast itself. There was a slight smell of electrical burning afterwards. It's about 15 years old and has a...

Anyone able to advise me on re-priming a Worcester Bosch Danesmoor 20/25 conventional boiler, after the oil tank ran dry? It's being refilled on Monday so I would like to be able to get things back up and running asap. Boiler is due a service anywaybut I'll never get an engineer in same day...

Hello again all Long time no post - but my bathroom saga runs on and on. Hope this is the right place for this. If not, apologies. Couldn't see where else. Installing a freestanding bath now and don't need one of those expensive chrome traps as the pipework is out of sight against a...

Have just fitted a new ladder type towel rail in the bathroom, so drained down the system, and now only half the rads in the rest of the house are heating up. System is conventional, ie not combi, oil boiler and header tank in loft. Pumps appear to be working and rads have been bled...

Just registered and here's my very first post - so hello to anyone reading this! I'm in the process of putting in a new bathroom and have got as far as installing a fancy new ladder-type towel rail instead of the old rad. I've used the old rad valves (inc a trv) but the trv does not screw in...
