Flowrate of top acess McAlpone traps?

[markocosic]

What flow rate would you expect these to handle without water pooling above the plug level?

At 15L/minute - no chance 

At 12L/minute - marginal

At 10L/minute - not standing in  puddle when showering 

 

I *think* it's just the nature of the trap. (smaller than a regular one by area)

 

Anybody measured a similar one and found the same?

 

Didn't have this problem the first time I used one in Cambridge on a 24 kW combi boiler!

 

I may stick an 8L/minute restriction in there before the wife notices the pool and comments. 😄

Some of the traps state flowrate:

...with 120 mm head...so standing in a 120 mm deep puddle?

 

 

In hindsight I think this would have made a better combo:

Fed into a 50 mm outlet.

 

- 19-23mm inlet teed into the overflow for the AC condensate (rather than my 32mm tee faffery)

- Not "cleanable from the top" but in practice if you slice through the hair trapped around the plug the rest can easily be pushed through the 40 mm section and out into the 50 mm part?

 

Or perhaps one of these two:

Or perhaps fuggit and put a 110 mm outlet gulley in the floor that the sink / shower / bath can run into directly in 50 mm without any traps? (just the single 110 mm gulley accessible in the corner of the floor)
