Thanks for that Slippy. It's still new in box so I give it back to them and spend an extra £20 on something better. Seen some Goblin Aquavacs on eBay for £50 delivered might get one. Other than that £60 in shed for a Vax 4000. Any recommendations anyone? Suppose this should be a new thread...

Hi, Been out and at great expense (£30) bought a B&Q own brand wet & dry vac as suggested. Will couple it to the vent tomorrow and see what crud it can swallow. One thing though before I start chopping my pipework about if this doesn't work. I have said the vent runneth over fast or...

I'll go and get a wet vac and try that. If it doesn't work can I cut the section of flow pipe out with the vent and feed joints and replace with pushfit (I can't solder) so there is new vent and feed joints? Thanks

Sounded a good idea. I turned the boiler off this morning and with a cold system I am still getting pump over. My expansion pipe rises about 7 feet above the main pipework and pump, I'd have thought this was sufficient head compared to your problem. Thanks for all input so far.

Elephant...... Are you changing the tank yourself? If you're having a heating plumber in you might get a professional opinion you can share with me on the pump over problem.

Think I'm going to have to turn my pump speed back up as I'm not warm enough. Any more ideas on what might be causing the pump-over seeing as my system is correctly plumbed? If Elephant_Guy reads this. have you sorted yours yet? Thanks

Hi Sounds like Elephant_Guy has the same or similar problem to me actually, my system isn't running out the overflow either. I only said the hot water was running out the expansion pipe but the water must be recirculating. Sorry if I confused anyone here.

I know the picture in previous post would explain itself to most people but just found the arrow and it is pumping in the right direction.

Boiler runs continous while warming up. It is Ideal W, no numbers on it but inside the door it lists about 6 different boilers and I don't know what I've got. Can't see an arrow on the pump, have to practically stand on my head to get to it. If you look at this picture of one it would be...

Heating been running for a few hours now with the pump on 2. Sure there is less water from expansion pipe but the house is colder too. Any ideas please.

Softus I have just been up the loft again and followed all the pipes. The pipe comes from the boiler and T's to the pump over pipe, then 6 inches later is the feed pipe from the tank, then 6 inches after that is the pump. After the pump the pipe divides to the two motor valves...

Will check the exact pipe layout later Softus, thanks for the info. Just seen too that the boiler dial is on maximum, would it help the pump over in the expansion tank if I turned it down? Used the website that was in someone elses post today about pump speeds and it says my pump should...

Pump pipes are horizontal. 6 inches away from pump towards boiler is a joint with the expanion pipe over the tank. 18 inches the other side of the pump is another joint where the pipe divides to two motor valves. In a word should the expansion pipe be running or not? If it's a...

So is it a problem that the water is running in the tank like this. Should the pipe over the tank not be running? A blockage, why and where? I know you're not here to see it but any ideas what it could be?

I'm also concerned about the large quantity of steam rising off the tank. Just found out the pump has different speeds and it is on 3. If I change it to 1 the water stops and it's a trickle on 2. Have left it on 3 but some rads don't get hot just warm.

Hi This is my first house with central heating and I don't know whats right and what's not. In the attic the curved pipe over the little expansion tank is pouring water into the tank. Does this mean the water is only going round that bit and there is a blockage or should this be running all...
