Fitting a 2litre expansion vessel

[eternaloptimist1]

I am fitting a 2 litre expansion vessel just before the the washing machine cold water intake.
The idea is that it will absorb the shock when the washing machine valve shuts rapidly as they generally do. I had no problem in the past because my cold water system was low pressure, supplied by a cold water cistern located high up in the roof apex. The washing machine now is supplied via mains water at about 2 BAR.

If at all possible, I want to install the vessel horizontally. Is there any reason I must not do so?

You can get water hammer arrestors which take up a lot less space than an expansion vessel

Thank you. I do have that very same one fitted. It does not do the job. I really do want to fit this larger vessel. Any reason why it may not be sited horizontally?

Horizontal O.K.

As above but it must be well supported.

Thank you. It will be fixed in place and be immovable.

Thank you. It will be fixed in place and be well secured.
