Dima Plumbing

My contractor Told me that I can move drain pipe closer to the wall ,so dishwasher would fit in,I called John and asked him to come and do it.As John came and assessed a situation he explained me that moving drain closer to external wall will cause a water freeze at some point and clog of sink and dishwasher.Of course I was disappointed, however at the same time I was happy that John told me the professional truth.He could charge me whatever amount and do it and leave me to deal with consequences later,but his professional ethics did not allow him to do it.Now I am looking for dishwasher that is less deep and thank you John for not letting me get in trouble
