Hi experts!
I just wanted to see if anyone could provide some insight on what seems to me a slightly weird bit of plumbing on my hot water cylinder.
The cold return from the coil is reduced from a 1" fitting down to a 15mm pipe immediately on exiting the cylinder, only to be changed up to a 22mm pipe a short distance away.
Photo shows the 15mm length of pipe (one end has a 28mm to 15mm reducer which connects to the 28mm to 1" coupler that fits the cylinder, while the other end leads to a 22mm to 15mm reducer used in reverse to connect to 22mm pipe).
I was thinking of binning that and changing the run to be 22mm all round, is it worth it?
Given that the pipes for all the other connections are 22mm what (if any) negative effect would having this 15mm reduced flow have?
Any insight on why this might have been done like this?
Many thanks in advance!
