Boiler Losing Pressure from Washing Machine

Indeed. Same schedule for one of the bathroom taps then.

You would have thought but neither the hot or cold taps to the sink or shower cause the boiler pressure to drop?!

There are 4 pipes running through the wall into that direction of the flat which I can trace:

1) Branches off to the cold water intake which I assume is the mains
2) Hot water out from the boiler
3) Heating out
4) Heating return

There is only 1 pipe with a significantly larger diameter which is the mains cold and it looks to me as though the plumbing into the utility room is connected to this from where the T joins.

I think it must some issue with how the filling loop is connected to re-pressurise.

My guess is that you are connecting into the filling loop point. Is there another similar sized valve near to it coming from the main cold feed?

So tee a supply for the WM off either of the cold tap supply or the loo supply. Cap off the pipe in the Utility giving the problem and just leave it be. Your immediate problem is solved and you can worry about the other later.

There is only one tap available.

I assume that the white goods plumbing should not need to go through the boiler as they are cold fill.

Could I therefore test by turning off the valves at the bottom of the boiler for the feeds/returns to see if this affects the pressure at the valve?

You could do that and if the pressure remains constant when you operate the washing machine, then that would confirm the feed you are using is plumbed incorrectly.

Using central heating system water through your washing machine and to clean your clothes can't be doing either much good!?

Does the tap you have connected to look like this?

shudder

With your suggestions and checking the feeds has helped I think?

When I turn the heating return valve off at the boiler and the plumbing to the washing machine on I get about half a litre of water out. Turn on the return valve at the boiler and I get about another 1.5 litres out before it stop's. Which to my understanding from guidance so far is that the WM supply is currently plumbed into the return?

No, it is into a pipe. I haven't connected this, it's been here since I moved in.

Sorry for all of the questions, I have an inquisitive mind and couldn't find a solution after searching Google for a couple of hours!

I will speak to the managing agents again once I can give them a cause. Apparently poor water pressure is not something that is in their remit!

Does your washing have a rusty reddish tinge perchance?

No, the machine will not run as there isn't a sufficient supply coming into it.
