How to Clean a Sewage Ejector Pump: From Start to Finish.I'd still like to know where the dedicated vent requirement is found in the IRC, but you're right, bus_driver, I'll ultimately have to cut through the roof if the local inspector requires it whether or not I understand it.

#Sewage ejector system vent code

P3113.4.1 Residential Code New York State: 'Drainage piping below sewer level shall be vented independently in a similar manner to that of a gravity system.' īy comparison, 'Phil H' notes that amended New York State code explicitly inserts the word 'independently': P3113.4.: 'The air pressure relief pipe from a pneumatic sewage ejector shall be connected to an independent vent stack terminating as required for vent extensions through the roof'. P3113.4.: 'Drainage piping below sewer level shall be vented in a similar manner to that of a gravity system.' He/she cites the same sections of the IRC that I find in the Mich codes. 'Homebild', who says that he/she is an 'ICC certified Residential Plumbing Inspector', asserts that the IRC allows non-pneumatic ejector pumps to be tied into existing vents. I found a discussion on the issue at the link far below, but it doesn't build my confidence one way or the other. For example, is it because the sump crock drains independently into the 4-inch house drain that it should also have an independent vent? Is there a specific paragraph in the IRC that is completely absent from the Mich codes? I suspect it's because I'm looking in the wrong place or missing some other subtlety. But I still haven't found the requirement for the dedicated crock vent in the Mich codes. I've been able to correlate all other advice precisely to the Mich codes. More than once the advice has either made the code book easier for me to understand, or it steered me to a different section that was more relevant to my question. I must confess that without the generous help of Lazypup and others, I'd go nuts trying to understand the codes just by reading the book. It helps me a great deal, then, to know which sections of the IRC are being cited for comparison to the Mich codes. If I seem confused, it may very well be because of Mich amendments. I have the current Mich Res Codes book, but not the original IRC codes on which it is based. Question: What size vents are typical for sewage pumps in Michigan? Thanks in advance to anyone who can help clear the water. 1.5' would be easier to install, but I'm leaning toward using 2' just in case either the pump or the inspector requires it. If 1.5' is sufficient, I'm not sure what is gained by going larger. I've also seen a suggestion that a sewage pump vent be one size larger than otherwise required - 2' instead of 1.5' in the post. At least he was certain that their pumps are not pneumatic. Of course, the same guy thought I was mistaken about 'pneumatic' and 'sewage pump' having anything to do with each other as one moves air and the other moves liquid. A company tech support guy said that a 2' vent is okay where code allows it, but that 1.5' would not meet the company's requirements for proper operation of the pump. 4 HP flush-up unit that has a 2' discharge and a 3' vent. The local big blue box store sells Star Systems. Question: Are sewage pumps typically pneumatic? Or does the IRC 2006 (not yet adopted in Michigan) require a dedicated vent regardless of pump type? (Lazypup, if you're listening, perhaps you can clarify the dedicated vent suggestion better than anyone.) I'd prefer to tie the vents together in the attic if code will allow it.

Lazypup suggested awhile ago that I install a dedicated thru-the-roof 1.5' vent for the pump (plus a second 1.5' regular vent for the fixtures, which is now installed).

Question: For the pump, is the vent serving the typical 2' discharge line, or the 4' line it pumps into? Otherwise, it appears that the pump can be vented like anything else - it can tie into existing vents and be half the diameter of the line it serves (but at least 1.25'). If pneumatic, a dedicated vent through the roof is required, sized based on the air requirements of the pump. Venting has me befuddled.Ĭode differs depending on whether the pump is pneumatic or not. Thanks to a suggestion from Lazypup a few weeks ago, the drain connection is all good. The Michigan Residential Codes 2003 apply, based on the IRC 2003. The future bath would have to pump the sewage up to the drain line. While walls are open for a main floor remodeling, I want to add plumbing vents to support a future basement bath.
