Help! Bit random, but anyone know about Megaflo hot water system? Has anyone experience of a Megaflo unvented hot water system (particularly plumbers/heating installers)? Am trying to clean the strainer in the cold water pressure reducing valve which the manual states should be removable by just unscrewing the black cap. However, mine seems to unscrew for a couple of turns and then just seems to be turning on itself; furthermore there is the sensation of it being held from below by a strong spring, which is unlikely as there isn't one according to the manual!. My question is: should this just unscrew easily or it is normal for there to be some resistance - and how much force is it safe to exert on it? Could it be that scaled up that it is just stuck (bearing in mind I am in a hard water area). Is it safer to get a new valve installed rather than run risk of knackering the old one and being without hot water? If so, anyone in the trade interested in doing this (South Lincs area)? Will end ramble here - if you've got this far without dropping off thanks for looking! Ian. |
