Should I Join sink waste to existing washing machine waste?

[Armitage Shanker]

I am installing a sink in utility room. Washing machine waste already exists and is the verical pipe with the flexib pipe from the machine poked down the top and a with a u bend at the bottow going directly to outside drain. Is it OK to put a tee joint into the verical pipe and join the sink waste to it? Is there a risk of overflow? Is there an alternative solution?

Or remove the washing machine trap / upstand and fit the kitchen sink trap with a washing machine spigot eg mcalpine wm1 etc

Many thanks for your reply. Would there be a danger of overflow if I simply tee into existing washing machine waste? Obviously wouldnt use sink while washer was working.
