    As above bud chemically clean the system sentinel x 400 leave in the system and run it as normal to break up sludge and magnatite up to 2 weeks then drain the system while hot and flush change the pump at this stage refill and add sentinel x 100 inhibitor vent the system and fire up the boiler you should see a improvement, knocking and banging pipework is normally due to pipes being installed poorly take the floorboards up have a look ease notches in joists wrap hair felt lagging where pipes can expand and rub , screw the floorboards down

    Thanks guys, I cleaned off all the sludge from the magna clean last night, rebalanced my radiators and I seem to be getting all rads on at high temp. Quite a few of the rads are not as hot at the bottom as they are at the top, maybe by 20% difference in temp.

    Last night I had no knocking in the loft, all the usual creaking/tapping when the heat up (but that can be dealt with later). However, the Boiler was still cycling up and down as if it was struggling to keep temp down.

    Can I ask, if it was the pump not performing or on its way out wouldn't you be able to hear the pumps speed vary too? Its just the pump sounds fine and I would have thought you would be able to hear that struggling in tandom with the boiler (if it was the ch pump)?

    Pumps can appear to be working fine, but are actually only half working. This can happen with nearly new pumps also.
    Usually if the pump is failing, the furthest rads from the boiler and also on drops pipework will not work well, if at all.
    Also make sure your system is balanced properly so that there are no easy circuits for the pump to do and therefore not properly heat some of the rads. If turning off some rads makes the others work better, this might mean balancing is needed

    Are you by any chance in a hard water area ? as you may have a slight scale build up as well , seems hard water area's suffer a lot more from sludge than soft water area's,

    Guys, on here nobody has really mentioned the magna clean system I have built in.

    I cleaned this yesterday so it was free from sludge.

    If I used the MC3+ rapide cleaner which is supposed to remove sludge/limescale etc would this be a good thing to try. My problem with this is with needing to power flush after but according to what it says on the sales adverts it "does not require a partial drain down".

    It does say this at the end "ADEY's new formula has been specially developed to deliver exceptional results when used in conjunction with ADEY’s best practice MagnaCleanse®flushing process"

    1. Would I be right to use this and do nothing else but add it to the magnaclean canister and walk away?

    2. The do an MC1 product which I believe is an inhibitor, can I, say in a couple weeks after add this into the cylinder.

    Or am I barking up the wrong tree and should call in a pro! its I have this magnaclean and that should do the job its purposes to do.

    I am not a plumber but if the rads are hot at the top and not so hot at the bottom that sounds like the bottom is full of sludge. I you guess the sludge wont heat up very fast.
    I would guess that you need a power flush to get the sludge out of the rads.
    If you have already removed 3 rads and refitted them you sound like you are OK at diy. So maybe a cheap way of doing a partial flush is to remove all the rads and flush them with a hose pipe outside.
    While this wont be as effective as a proper power flush it might be better than nothing and get you going till you get a new boler. Obviously there is a possibility you could damage pipe work etc removing and refitting rads plus the need to refill with corrosion inhibitor etc.
    One thing to remember is that normally a power flush will be required for a new boiler install. So it could actually be more cost effective to have the boiler replaced and power flushed if you consider that a new boiler will probably be more efficient than the old one so you will save on fuel.

    Sorry, having some problems, repeat post clarified.

    Guys, on here nobody has really mentioned the magna clean system I have built in.

    I cleaned this yesterday so it was free from sludge.

    If I used the MC3+ rapide cleaner which is supposed to remove sludge/limescale etc would this be a good thing to try. My problem with this is with needing to power flush after but according to what it says on the sales adverts it "does not require a partial drain down".

    It does say this at the end "ADEY's new formula has been specially developed to deliver exceptional results when used in conjunction with ADEY’s best practice MagnaCleanse®flushing process". So it does look like it needs flushing if I was to talk that route.

    1. So mc3+ needs a power flush?

    2. They do an MC1 product which I believe is an inhibitor, I assume this wouldn't help until after a power flush?

    I have this magnaclean and that should do the job its purposes to do?

    For info: the boiler is only 6 years old, this will be when the magnaclean was installed, so it should have been flushed then.......

    Sludge wouldn't cause the boiler noise ramping up/down on a 10second cycle upon start up for 20minutes or so would it?

    The key word there kev is "should" but was it powerflushed or chemical cleaned, guess we don`t the answer to that do we.

    If you add a good quality system cleaner (I Only use Fernox Product's) F5 , then run system it will start to dislodge sludge, But you will need to clean the filter every couple of days, but first remove rads and rinse though with hose, bit of a time consuming job but if you are looking to save money that is the way to go, DIY. Did you say that someone quoted £500 to replace pump and power flush system ? if that's so you need to get him round asap, You need to find out if you are in a HARD WATER AREA, as you may need to add extra chemicals to treat system.
