How do you flush yours........

I hook my new rads to the kitchen sink for half an hour or so then rinse through with some di and I'm done, though I've just purchased a cheap pump to assist :)

First run with regular water. Then second time with di water for half an hour or so.
 
Gatecrasherlok,

What filter is that and pump?

Last time i did it i use the hot tap with a Hozelock fitting to tubing. Note to self do not touch the rad, they get hot!
 
I have almost the same as gatecrasher. I use a mains pond pump and the same filter housing, can't remember what micron size filter i'm using though.
 
Okies guys

I use the following :-

A pond pump. I got mine from a local aquarium shop for £10

A bucket or container of some sort for the pond pump to go in like a used protein shake container. Acts as a resevoir for the pump

Regular house mains filter (High Capacity Water Filter)
Can be bought from your regular DIY retailer or plumb shop. I sourced mine online for around £12. Bigger retail chains sell for more but if you look around you can find one pretty cheap like mine on the interwebs.

You will also need some fittings to go on the water filter. Again these can be sourced from a garden or DIY centre/retailer for £2 a fitting. Mine are a little bigger than half inch but a little force and you can get half inch tubing on no probs. So in the picture that will replace the ptfe tape and gaffer tape going to and from the filter.

Hope this helps you guys. I swear by it, gives me peace of mind knowing that i have cleaned out the rads thoroughly. without the hassle of the old school shakey shakey


Here is where I got the whole idea from so props to LazyMan.

In an ideal world yes but when your dealing with so many different types of materials, liquids etc, it is inevitable than some sort of grime or substance will find it's way into the loop. The added fact the way radiator manufacturing is atm, shavings, bad metals may still be be in the loop. All this setup does is try and filter out as much as possible and as easy as possible.

As I said earlier that peace of mind that you have done everything possible is worth that extra money spent on doing this.
 
I let my local council filter out any foreign bodies in my blocks/rads when I flush my loop, by sending the water in one end and straight down the bath plug hole the other and on to their sewage treatment works. The council also happily supply mains pressure water for me so I don't even need to use a pump :)
 
You'd more likely find some 3/4" npt male to 1/4" bspp female adapters then use some standard wc fittings ;)
 
I went for res/pump - filter - radiator then back to res/pump. TBH I think the orientation of whether radiator or filter is first does not matter too much as the filter will get most of the grime out after 10 mins or so.
