Megaflow

Hi

Getting Desperate

We had a megaflow system installed 2 yrs ago and worked great, recently the overflow has been dripping constantly, and we run out of hot water v quickly (1 x 15 min shower).
A neigbour said to re-charge it so I did as the instructions said , but after 30mins with a hot water tap running and the pressure valve released (thus soaking everything under the overflow) it still wasnt empty! The water supply tap to the megaflow was turned off - surley it dosn't take this long to empty - Does it?

It could if it were a big tank and a slow dribble - several buckets of water.

Turn inlet off and open a hot tap - that'll let most of the water out without having to hold the PR valve open. Then hold the valve open to let air in and the rest of the water should come out.
Can be quicker to put a hose on the thing's drain cock.

Its a 250 I think - Stands about 5ft tall, two heating elements (may actually be an older model as sat in its box for about 4 years before being fitted)!

Do you think this will fix the initial problem of running out of hot water and stop the over flow dripping?

Thanks

Sounds like 2 different faults. The mega flow requires it's air bubble to be regenerated at least every 12months 4 its warranty. You should only drain it by the drain cock & open the PRV to let air in then u know its low enough. As 4 running out of hot water ,how long is the boiler on 4 & at what rate was it dripping . 250ltr give's a very very long shower.

this is not a job for the customer, anyone installing, servicing or maintening this sort or equipment by law should be BEPEC approved, and will have a I.D card to prove this. call a qualified egineer, this sort of un-vented unit can blow half your home away mate!

Re-establishing the air gap is something an owner can do. Megaflos even have the instructions on the side of the can.

not a can it`s call a cylinder by the pro`s. by all means re-charge but after that call a qualified engineer.

Bugger .I thought it wa called a tin, not a can.......I`d better get one of those acs unvented tickets so I can fit one

 

[plumber (new blood)]

no I`am sure its a cylinder??? thats what i learnt at unvented school anyway

Oh bugger, you mean my citb certificate isn't worth the paper it's writen on?

Still I'm glad you've decreed that householders can't re-establish the bubble, more work for me, loads a money!

citb also, don`t know of any others. telling the customer to fault find on any bit of kit i think is dangerous, ok re-charge the dam bubble,but maybe at this point the customer should be informed of the requirment to service these thing,christ we all know what happens if they go wrong.

Do we really, perhaps you should enlighten us.
