Hi,

I'm new to the forum but hoping someone will be able to help me?

My en-suite was refurbished about 5 years about before I bought the house and at the time the plumber fitted a New Team shower pump with 22mm flexi hose connected going onto 15mm pipe work running to the shower and hot water tank and sited in the 1st floor airing cupboard.

Recently the pump despite being incredibly noisy started to leak so after doing some research I’ve bought a Stuart Turner Monsoon 2 bar twin 46415 to replace it. The only question I’ve got is that Stuart Turner suggested I now need 22mm pipe work to replace the 15mm I have currently - this seems strange given the current pump has been installed with 15mm going into 22mm and apart from gong faulty and being noisy has given no issue. The guy at Stuart Turner seemed to suggest this was a new recommendation if so what is the aim, more to the point if I simply replace the pump and maintain the current pipe work am I going to have issues?

I guess what I’m thinking is that the current pump although noisy worked fine to boost the shower, given the expense of getting a plumber to replace the pipe works what if any benefit will I see?

Any thoughts would be most welcome; I really don’t want to have to replace the pipe work if I can avoid it?

Many thanks,

Ian
 
It will be fine in 15mm i wouldn't bother changing the pipework unless it was really easy to do so. I'm sure that in the latest Stuart turner instructions state it as a recommendation or other.
