Rated 4 out of 5 by Lack of details of pipe sizes The total lack of any information on what size connectors to use makes life very difficult for the DIYer. When I asked the branch they told me they were only suppliers and did not give advice! Still don't know what size to use! 21 Jan 2016
Rated 5 out of 5 by Hot water tank The tank arrived well packaged and a fast delivery time for the area where i live. The tank was well insulated and as described. As in a previous review it would have been very helpful to have a list of the number of connections on the tank along with the connection sizes which in this case was 1 inch. As the tank has only been fitted for about two weeks i cannot say what the reliability is although i have given it the five stars in anticipation. 3 Dec 2015
Rated 5 out of 5 by tapings on cylinder One person has suggested not to use jointing compound only on cylinder as threads are a little generous You never ever use jointing compound only on male and female threads for water. This is only used on gas threads. Use ptfe tape,locktite or if not potable you can even use good old fashioned hemp! 14 Sep 2015
Rated 4 out of 5 by Direct Cylinder Cylinder is of decent quality. The one I received was supplied with all connections being 1" female threads. Screwfix could add this to the description to make things a little easier when it comes to knowing what fittings you might need. It is very well packaged so you can't see it without opening the box. Also it's worth noting that it's not supplied with an immersion heater or a plug to blank it off, so that will also need to be ordered separately. For the DIYers... If you are connecting to 22mm pipes then you'll need 4 x catalogue number 61955. If you are not using an immersion heater you will need a plug, catalogue number 51855. I'd advise against using jointing compound on the threads and instead use ptfe tape as the threads are cut a little generously and the tape is needed to gain a good seal. Jointing compound / paste is not rigid enough to take up the spaces on the threads. 9 May 2015

Answer: 
Thank you for contacting us. The cold feed fitting on the Screwfix 900 x 450mm Direct Copper unit is 1" female, but this can be adapted by yourself to connect to 22mm if required.

Answer: 
Thank you for contacting us. Copper cylinders can never be connected direct to the mains supply, they need to have either integral header tank (combination units) or separate header tank.
