Does it need a pressure reducing valve of 1.5 Bar? I've not seen the job just got sent a PDF of the cylinder installed and a photo of the serial number along with the information "the flow to the shower is poor or any item feed of the balanced supply from the group set is interrupted if any other item demands water hot or cold except the downstairs kitchen sink ( which I understand why that is excluded). |

Could just be shit in the Group Filter dear boy??
I’d do a Flow & Pressure test at the Kitchen sink or wherever the Mains enters the gaff.
It’s supposed to have the Group Filter cleaned on its ‘annual’ service!!

It’s supposed to have the Group Filter cleaned on its ‘annual’ service!! Morning Dick. I've asked the question and their reply was "no known service visits on the install however the boiler has history of repairs/service visits." My plan was to just fit a new valve because I expect the internal filter to be as good as choked, that's why I wanted see if others knew of any good suppliers for such items in there neck of the woods. |

I’d check with Gledhill that their cylinder operates at 3Bar. The item you Linked to was lower than 3Bar. Copper UVCs operate at a lower pressure. You don’t need to use a Gledhill Spare, just as long as the Inlet Group is the correct Inlet Pressure to the cylinder & the Pressure Relief valve is as their specification also👍 Reliance Water Controls Inlet Groups are supplied with most Unvented Cylinders. However, other manufacturers’ units can be used. Caleffi are generally cheapest; www.unventedcomponentseurope.com/caleffi-22mm-inlet-control-multibloc-valve-group-533002cst-2.html/I presume you’ve a G3 ticket? |

Yes mate a standard 3Bar Group is too high a pressure.
Unfortunately, I can’t find a cheap 1.5Bar Group.
