no proper flow.partailly blocked pipes which fill up to capacity with shower water which eventually slowly drains; the flow from a flushing toilet after some time(you stated; 45 minutes) is simply because the shower wated has drained....clean the pipes check for roots from neighbouring trees/shrubs, remove ,seal the hole and the flow should normalise

I had a water pipe break on a Friday afternoon, when I was expecting company the next day. I called Drains N Pipes and they were able to come out and repair my pipe immediately. The plumber they sent was very nice and had my pipes repaired and was out the door in under an hour. The rate they charged was fair and I am very happy with their service. I will be recommending Drains N Pipes to all my friends.
