Hi everyone

I am new to the site and have had a problem with my Megaflow cylinder, which is almost 3 years old, in my airing cupboard. The oveflow pipe has been constantly dripping so today I followed the instructions on the side of the cylinder and also watched the heatteam video and opened the hot tap in my cloakroom while opening the pressure valve. I was advised it should take 15-20 minutes for the water to stop running fom the overflow and the hot tap, but the water stopped dripping from the overflow within 3/4 minutes, thus stopping the dripping, but the hot tap still had water running out.

Can anyone advise me if I have done something wrong? I am getting very worried it is potentially dangerous.

Many thanks

Jane

you have to let AIR in rather than letting water in

you need to re energize the internal expansion vessel so as the sticker says

1 turn off water
2 open hot water tap
3 twist and hold up the T&P valve
4 wait untill gurgling stops
5 turn off tap
6 turn on water

Done

Thanks for your swift reply. I am being thick? The video on the heatteam site to solve the problem shows that water should be running through the overflow pipe and also from the hot tap for 15 - 20 minutes approx until the water stops flowing from both the overflow and the hot tap.

How to replenish the air-gap on a Megaflo Cylinder
Water intermittently dripping / flowing from the overflow on a
Megaflo Cylinder is usually caused by the air-gap not being fully
charged. Follow these instructions to replenish the air-gap and solve
the problem.
Step 1.
Turn off the mains
cold water supply to
the Cylinder, this is
usually found near the
Cylinder, OR if you
can’t find this valve
you can turn off the
mains stop cock
which is usually found
under the kitchen
sink.
Step. 2
Open the lowest hot
tap in the property.
This would usually be
the kitchen sink but
any sink of low
latitude to the
cylinder will be fine.
Step 3.
Hold open the
temperature /
pressure relief valve.
Water will pour from
the valve for up to
15/20 minutes. You
must hold the valve
open for this time. If
the water hasn’t
stopped flowing after
this time the mains
water supply may not
be fully turned off.
NOTE: Take care, as the water from the valve
will be hot.
Please refer to the disclaimer statement located on the
‘How to guides’ section of the heateam website.
Step 4.
When water stops
flowing from both the
valve and hot tap
close the temperature
/ pressure relief valve.
Step 5.
Open the mains cold
water supply.
Step 6.
When mains water is
turned back on water
will pour from the hot
tap. Close the tap.
If the process is unsuccessful, water continues to
drip from the overflow, then you should contact
your installer or service engineer for assistance
