![]() The watercloset sits on the pad and the pump unit is in the space between the back of the watercloset bowl and the wall. "Low-Pro Series" prouces a complete self contained sewage ejector pump system that has a low pad equipped with a closet flange on which you can install a conventional watercloset. There is another alternative that offers a great compromise. Another serious drawback is that they have some rather complex internal parts that are often difficult to locate for even the minor maintenance problems associated with waterclosets. There are a number of "UpFlush" toilets on the market that have a built in sewage ejector pump system however they are very expensive and most have no provision for auxillary drain inputs to serve a lavatory, tub or shower. Installing a conventional sewage ejector pump assembly requires cutting into the concrete which adds considerable cost and labor to your project. I still think it was a lot of money for the time he spent there. He had an assistant with him who was my nephews school teacher who knew about much with plumbing as I did. They told me 2 guys at x amount per hour. I called some else who would not give me an estimate. Another plumber I called canceled on me several times so I gave up on him. That was not with running the copper pipes. I then got another price of $1700which was better but seemed like a lot. I could do that myself but I almost flipped out with that price. I first estimate from my dads friend told me $3500 which included doing the copper pipes for the sinks and stuff. Like I said before, I did all the hard work of busting up the concrete and halling it up the stairs and had everything laid out for the plumber all he had to do is cut the drains apart and move or add thing around. I am also doing a total basement remodel and had to move a vent pipe on the other side of the basement and had the upstairs bathtube drain reworked to increase my ceiling height, tucked the toilet drain over that came down from the upstairs bathroom, and moved a drain for my bar. Once that floor is repoured with concrete you cant take it back up to to make adjustments so that part I hired out. I do almost all my home improvement like framing, drywall, electrical, etc. Here again, in order to connect a sewage ejector pump system you must have a 4" house drain and house sewer line and depending upon the existing load, it may require a 6" line. The Uniform Plumbing code requires the sewage ejection pump to be rated at 20gal/min and the discharge must be computed at 2DFU per gal/min. The bottom line, unless you have a 4" main drain and 4" house sewer you could not install an upflush toilet or sewage ejector pump system without changing the entire main drain and house sewer line to 4". ![]() In most cases residential structures only have a 3" main drain and house sewer line and the IRC limits the load on a 3" horizontal main drain at 42DFU and a 3" horizontal branch line at 20DFU. The gravity flow line receiving the discharge from the pump MUST BE capable of handling both the existing load on that line plus the additional 21.3DFU's. This means the absolute minimum load is 14.2gal/min x 1.5DFU = 21.3DFU. ![]() and the output load must be computed as 1.5 DFU's (Drainage Fixture Units) for each gallon per minute from the pump. The International Residential Code requires all "sewage ejection pumps" to have a minimum capacity of 14.2gal/min. Now, while there are dozens of upflush toilets and sewage ejector pump systems available on the market, you may not be permitted to use one in your structure. There are a number of code issues to be considered here.įirst of all, the upflush toilets and sewage ejection pump systems may only be installed in instances when the finsished location of the desired waste receptor is below the level of the structure gravity flow drains, of to put it in simpler terms, if the house main drain is under the basement floor you are required to connect to the main drain by means of gravity flow drains in the normal manner.
