Hi everyone,
My first post here! ....
Let me start by saying I am not a registered plumber, but I am an experienced DIY enthusiast, with many successful plumbing projects behind me and keen to learn.
I have a fairly basic question - hoping you can help; I am currently doing work at a flat where both hot and cold taps are on a gravity fed supply, coming from a small cistern mounted as high as possible (the outlet from the cistern is approx. head height). The cistern also supplies a vented indirect hot cylinder, heated by a has Central Heating loop. So - fairly conventional for an older style property.
OK - so my question!; am I right in thinking that the water flow (pressure) at the hot and cold taps should be approximately the same?? Reason for asking is that the flow at ALL of the hot taps is actually extremely low; significantly lower than the cold taps, which have good flow. I would expect a slight loss of pressure for the hot as it goes through the cylinder & fittings, but I think the flow at the tap will be mainly governed by the 'head' between the cold cistern and the tap, which is approximately the same for both hot and cold.
My suspicion is that there is a restriction due to scale/debris in either the inlet or outlet fittings to/from the hot cylinder. I would really appreciate the experience of members on this point - and anything else I could check before taking the plunge and inspecting/changing the cylinder and/or fittings. It's a really tight installation with very little room to move around - and I can tell it's going to be quite a job!
Other relevant info; I estimate the age of the cylinder at about 10 years.
Many thanks in advance.
