hello all
i've searched through and found similar problems but not the same, so forgive me if i ask a basic question!!
system as follow:
potterton prima b boiler,
HW tank upstairs in airer, air splitter tank thingy, header tanks in loft directly above,
myson SMC SD53 pump and,
Honeywell V4073 diverter valve.
problems as follows:
while back (few weeks) lost all CH, local CORGI plumber diagnosed faulty diverter valve, quoted £160 for new valve (plus labour and full system drain??). i knew this couldn't be right so paid his call out fee and sent on his way. duly ordered and fitted new honeywell valve etc (£60 plus cussing), system had no leaks, valve all working fine (internals zipping back and forth according to HW/CH off or on at controller). feeling happy with self and strutting as man of the house (me big man and can fixum )
then.... within a few minutes....... pump not seeming to work, no real noise and very very hot to touch, hotter perhaps than surrounding pipework, valve working but again no heating in house, much confusion and cussing again. then the whammy! pilot light noted to be out, "mmmm" i thinks, "its not windy! why has that happened?" jumps up on kitchen chair to relight... click click lit, wait turn knob, pilot goes out???? tries again.. same thing, wait a while same again!
aargh! now sat here very cold, feeling daft, wife is sulking and we have no heating or water (have put on immersion for HW at least so wont smell).
why is this?
was the origional problem misdiagnosed?
i think the valve was stuffed as it didnt seem to be working like this one is (ie you can hear it turning back and forth according to the settings, the last one wasn't doing that...it would turn off CH but not turn it on).
has the pump gone too? was this the real cause or is it just coincidental?
the pump is 10 years old but the valve was replaced (by previously said plumber) about 5 years ago.
any help gratefully received!!! you may well save my marriage!!
(ok well not really, shes forgiven me worse things than being a crap DIYer!)
regards Jon
