Dear all,
I recently got a gas engineer installed a new boiler and an unvented cylinder & expansion vessel in my house, replaced the old boiler, vented cylinder and water tanks in loft.
Just after a month of installation, last week, the house lost hot water, it was because the cylinder leaked water heavily, we found it leaked to downstairs utility room via underground hot water pipes which could see cracks or fractures and leaked water.
Today, the water burst out from bathroom sink tap which was broken/separated from the sink, flooded all room. We can see the tap was broken into two parts,
So we suspect it is water pressure made the underground hot water pipe cracking and sink tap broken into two parts?
I heard the installation of unvented cylinder & expansion vessel will increase the water pressure on the pipes, do you think what happened to my house is the cause of the installation of unvented cylinder & expansion vessel?
Notes: the house is 40 years old, the pipes underground are old. The house previous owner was an over 90 year old single lady who sat to use shower, the house could not stand up to use shower as the water pressure was very low.
Since we moved in, we got unvented cylinder & expansion vessel installed to have good shower pressure, so is this the reason that water pressure increased and damaged the water pipe and sink tap (sink tap might be quality issue, but shouldn't be broken by water pressure?)
If it is water pressure cause the pipe broken and water leak, what should we do? Change the pipes??
Please help!
Many thanks!
