I've had some estimates done for sub floor drain systems (which I've seen in this bulletin board possibly referred to as french drains?) done and they are asking for around 4,000. In the most recent "Family Handyman" magazine there is an article on how to do this yourself. I am considering this possibility as I figure I can save at least 3,000. The article however is fairly basic being only 1 page in length. I have some additional questions I would like cleared up before embarking on this project.
1. Does drain tile have to slope towards the sump pump? or is it standard to have it level all the way around?
2. What do I do about pipes embedded in the floor? My assumption is that I just stay away from them with the jackhammer and if I need to get closer use a maul and masonry chisel. In regards to question 1. If I have to go under the pipes with the tile it would negate any slope towards the sump pump.
3. At a recent home show one of the exhibitors said that these systems have a tendency to get backed up because the tile gets silted up and blocked. Is there any way to prevent this during the installation or will I have to have the tile checked and cleaned out periodically?
4. What type of concrete do I use? Is it feasible to rent a mixer and do it myself (60 cubic feet)?
5. Is it acceptable to run the pump discharge pipe about ten feet in the basement before outleing it ouside? (I want to oulet on the other side of some concrete steps where I think it will be less noticeable and can safely run away from the house)
Any additional information, suggestions, or helpful hints would be greatly appreciated.
