Salamander S Flange fitting to protect a shower pump, full D.I.Y.

Fitting a S Flange to a Salamander shower pump, the S Flange stops air from entering the system and causing pump failure.

I had a salamander pump fitted by my plumber, no flange valve thing but it was on the floor at the bottom of the tank. It lasted 4 mth, got another pump fitted and exactly the same thing happened. We then replaced the pump with a Stuart Turner pump, all good so far. I tried your repair technique and yes our impellor was also stuck, quick turn with the wrench and it’s free again….sorted. Thanks for a great video 👍

So you don't need the s-flange if the pump is on the floor next to the hot water tank, any air would go up the expansion pipe

[@geofus]

That’s correct, but Salamander said to have a full guarantee on the replacement the S Flange would have to be fitted.

[@iangascoigne8231]

I hope you remembered to flush the pipe through to remove any residual flux as that can damage the pump.

[@Roblovesbushcraft]

Did you use the 28 into 22m reducing kit for the vent take off?

[@geofus]

Yes I did, it comes with the kit.

[@ILLYRIANW0LF]

Is the Pump meant to be that loud when operating??

[@RadDougall]

They are annoyingly loud yes.

[@Roblovesbushcraft]

Could you have bunged the cold water tank then drained the cylinder. Surprised you didn't use a lever valve tbh.

[@geofus]

Yes could have but would it have saved much time ? Again I could have used a lever valve, but the gate valve is free flowing and probably will never be turned off again, the salamander pump comes with isolating valves on the flexi connectors, just in case it needs removing.

[@Roblovesbushcraft]

@@geofus Thanks for the reply. Nice vid all the same

[@tomold6224]

It’s best to leave cylinder filled drain a pint of water then unscrew flange then drain 5 litres once cracked and then install a flange stops cracking the cylinder

[@actorlyric]

When the pump sits above the cylinder you need to fit an anti gravity loop, which you haven't done! Or dare say you know what one is!!
