I am in need of fixing my standpipe, the landlord emptied the sand after last season and in the process shattered the standpipe, there is still room to put a coupler and new pipe on, so my question is how tall is the standpipe ? if I was to stick a tape measure down to the pipe to the bottom, what would the top measure be ? The filter is a Dreamline Model # S190TSCP. Thank you for any help !!!
