Rated 2 out of 5 by from Problematic Bought this cylinder to upgrade for a customer who wanted more stored water . Was disappointed that I had to buy 1’’ connectors but that wasn’t too big a deal . I was more annoyed that after fitting it , I found that the coil was leaking from where it hadn’t been tightened up properly from the backing nuts holding it in place . I had to cut out a rather large section of the lagging away so I could sort the problem and tighten the backing nuts myself ! Shouldn’t happen. First time in 40 years I have had this , wont use RM cylinders again and no doubt there warranty wouldn’t account for much either as they would just blame the fitting

Rated 5 out of 5 by from RM Cylinder I bought this cylinder as a replacement for my 20 year old Telford due to it leaking from one of the welds. I ordered the cylinder on Sunday morning and it came into my local branch on the following Tuesday. A Good quality cylinder and seemed to be of an average value, I like the fact that the cylinder has its own shower feed to save you having to use a Surrey flange when fitting a pump. Fitted the cylinder that evening and only had to alter a couple of the feeds. So far so good so would recommend this cylinder. You will want 3 inch male irons and 2 inch female irons to go with the cylinder.

What size immersion does this tank take?

Asked by: Steady18

is this cylinder gravity fed to the coil

Asked by: rod8
Hello rod8, All cylinders are standard for Pumped systems only. If a cylinder is required to work on a heat source such as solid fuel/gravity a special cylinder with gravity coil is required. This type of cylinder would not be available from Screwfix and would need to be ordered from a plumbers merchant. Thank you for using Q&A SW

Does it come with connectors on the coil flow and return, and on the hot and cold?

Asked by: NDSEssex
Hello NDSEssex, Just checked this with our supplier, RM Cylinders, they have advised these cylinders are not supplied with connectors. They are 'ready to receive'. The hot & cold points are 1" BSP female, the coil flow & return are 1" BSP male. Thanks for using Q&A, KC
