Central Heating

[1UselessDIYer]

Please could anybody assist me, how difficult would it be to powerflush the central heating system by myself.

countless threads on this matey. going by your name. pay someone . get a couple of quotes based on ALL DAY not just the morning.

why do you need a powerflush btw?

Got a blockage between the boiler and the hot water tank. Is their another way that you know that would unblock this stretch of piping.

cut it out and replace it.

how do you know its blocked?

I have managed to remove the pump having emptied the system first, then opened the cold feed which allowed water to flow out, then opened the hot feed, no water came out. I then pushed my finger onto the opening and felt what seemed a lot of grit or silt. I prodded with a screwdriver but it seemes a solid mass in this pipe. I managed to remove a small amount of grit but still not working.

Erm, have you disconnected at the boiler, or the cylinder, or somewhere else?

A powerflush won't unblock this.

So what your saying is, the only soluition is to cut out the area of pipe and replace it. the only proplem is although I have managed to find this blockage, is it possible their would be other blockages back towards the boiler.

 

[Softus]

Have you disconnected the boiler connection at the boiler, or the cylinder, or somewhere else?

 

[1UselessDIYer]

Having replaced everything, the bolier is reconnected at this time.

 

[Softus]

OK. I'll try a different way of asking:

opened the hot feed

Where?

I then pushed my finger onto the opening

Before I let my imagination run away with me, can you explain where this opening is?

The opening is the connection at the bottom of the pump, it!s in the ubend but I dont know how far the blockage goes. See picture attached

Oh FFS, I'm sick of seeing that photo and wondering what's hidden in the shadows. We had the same problem on your other topic.

Please, pretty please with sugar on top, could you take a decent photo, and then stick an arrow on it to indicate the connection that you're talking about?

Just in case you can't, and just in case the connection is the gravity return from the cylinder to boiler, and just in case the grit you mentioned is inside the cylinder coil, then you need to disconnect it again and remove the grit without poking a hole in the coil.

Trying to get a decent image for you. I believe the blockage is where the pipe comes out of the bottom of the pump then its like a u shape which then goes back up to another pipe.

 

[Softus]

Well if that section of pipework is blocked, why don't you just replace it with brand new pipework?

I dont suppese you would have any idea of the cost of this job?
