Heater... let me get this right?

Now one of the cars previous owner was was some sort of hydrolics plumber and has fabricated some bits..well quiet a few actually. These are the steel return pipe from the water pump to where it splits to the heater and inlet manifold. He (or she indeed) also fabricated the tee at the rear of the inlet manifold as it had clearly rotted off leaving a single outlet. In theory all this replicates the original pipework.

My problem is that having drained and flushed out the system including the heater matrix I cannot get water to flow through the heater. To be honest I do not know if the heater worked before I drained it as this was last year. What I have done is removed the heater valve, cleaned it up and ensured it is working. Refitted the bowden cable (now there's a blast from the past!) from the heater control correctly adjusted. Ensured water flows through the heater when the valve is open and not when closed. Filled the system and run till hot. Closed the inlet/return flexible link pipe with a brake pipe clamp to force hot water through the heater and.......nothing. Both pipes to the heater stay annoyingly cold. I can only think it is an air lock in either of the two pipes feeding the heater as they are both well above the level of the radiator.

So questions are how the hell do you bleed the heater and what stops the airlock reappearing when the rad cap is removed, and why should water go through the heater at all when it can just return via the inlet/return link pipe. Am I missing something here? Please help as I feel stupid
Still, at least I've not seen any oil drips so far Adrian

  Be careful Mr B,i'm sure i'm not the only Triumph owner on here who has ,shall we say,fluid leakage....................As for your air blockage,try undoing the outlet heater hose whilst the engine is running(but not too hot)and let some water and hopefully air out.Don't forget to put a drip tray under the car to catch your drips....

    that's strange, from a urological point of view, gentlemen most often have trouble with poor flow, especially at night as the years wear on, it's the ladies who are prone to inadvertent escapes
    
    those who know what I'm talking about, yes from first hand experience, those that don't your time will surely come

      My time is usually 2.30am but enough of that. Ms 'M' reported excessive leakage when sneezing, coughing or laughing....blames childbirth apparently...never affected me that way! (keeps head down for next flaming!!)

        I used to have problems with liquid flow around 11pm every evening, until the advent of 24 hour drinking... it's been flowing freely ever since....
