Polytank Cold Water Tank 25gallon (UK) 690 x 515 x 520mm is rated 4.8 out of 5 by 58.

Rated 5 out of 5 by from Polytank Installation Screwfix were great when I had to take the unopened original tank back as, although it went through the loft hatch, it could not be maneuvered once up there. So, my advice would be to check the tank can be placed into position before opening. As a DIYer, the instuctions are tailored for anyone to follow and they state to use a hole cutter of two sizes, 27mm and 29mm, so ensure you have these before you start work. Installing it was easy, but beware you will also need a tank connector tool to hold the dogs on the fittings, or, a cheaper solution would be to buy alternative tank connectors which have an internal hex nut instead. Other than that, everything is included except insulation for the top of the tank, but I had the insulation left over from the old tank to complete the job. Carefully clean out any swarf with a damp cloth before filling unlike the one I took out which was full of all sorts of gunk.

Rated 4 out of 5 by from Polytank 515x515x530 Customer said a 24inch circular tank was leaking by the outlet and could see a crack. I gambled and bought this tank that should fit through a loft hole in a house built within the last 60 years or so. Great that everything is in the tank and it fitted a dream. New tank should last well beyond it`s new owners.

Rated 5 out of 5 by from A good robust CWF polytank Just managed to squeeze it into the loft after removing the opening surround i.e. check loft opening before buying! This tank is a lot more robust looking than the one it replaced and that had served for over 40 years so this should last forever. It was very easy to install though I had to overcome some difficulties caused by myself. Everything connected well after following the instruction leaflet which has all the details that you need. At the time I wasn't well and very tired and cutting the main water feed without turning off the supply would have been a laugh to watch and you know it's difficult to completely stop a drip from the ball valve water supply elbow when you forget the fibre washer! I used to be competent once, honest.

Rated 5 out of 5 by from Solid tank at a good price A well made tank, much more robust than many of the plastic tanks i have seen. All the fittings included, including the inlet reinforcing required these days, so you are ready to go. The ballcock valve and tank connector appear to be quality made so all in all, it should last a long while before any servicing.

Rated 5 out of 5 by from Perfect replacement Had to replace an old metal water tank that was seriously rusting. This was a good well made product that fitted the bill perfectly. Don't have to worry now about the old metal tank rupturing and having to replace a ceiling.

Rated 4 out of 5 by from Good Good tank for the money. There was a bit of damage to the seat of the ball valve which meant the service valve would not have sealed up to it but luckily i was using an elbow and olive instead so it didn't matter. Would buy again.
