Five hundred gallons of septic pump tank, 60 inches across
The Snyder SII-PT2S is a 500 gallon septic pump tank in black polyethylene, carrying the manufacturer part number 5170000W94201 and listed 60 inches long, 60 inches wide and 63 inches tall with a 60 inch diameter, at 182 pounds empty. The sheet gives 4,170 pounds for 500 gallons of water at 8.34 pounds per gallon. There is no specific gravity rating and no max contents figure on this sheet, so neither is printed. The published fittings are an inlet listed as 4, an outlet of 4 inches and a 24 inch manway. The service limit reads 130 F / 54 C and the warranty is listed as a 3 Year Warranty. The sheet also carries a restriction that belongs on the front of this page rather than the back: not for sale, use, or shipment in Florida. No state approval, code listing, burial depth, cover or traffic rating, compartment count, pump, float or riser is published on this sheet, and this page asserts none of them.

Three plants on one sheet, and one state it cannot ship to
The freight story on this tank is unusually good and it comes with one hard limit. Three plants are listed, Chowchilla, California, Marked Tree, Arkansas, and Philippi, West Virginia, which puts a West Coast, a mid-South and an eastern moulding point behind the same part number, and on a 500 gallon vessel that spread is worth money: the shipping size is 60 inches square and 63 inches tall, which is a bulky, light shipment whose cost tracks distance and trailer space rather than weight. The freight class reads LTL under NMFC 156600-02, a mode rather than a numeric class. The hard limit is the sheet's own: not for sale, use, or shipment in Florida. That is printed exactly as the sheet gives it, it is a restriction rather than anything else, and it is the first thing a Florida buyer needs to know before reading any further. Everything about siting this tank is a question for the person designing the system rather than for a product page. The sheet publishes no burial depth, no cover rating, no traffic rating, no bedding specification and no compartment count, so nothing here tells you how deep it goes, what can drive over it, or what has to be under it. Those come from your designer, your installer and the authority having jurisdiction in your county, and they come before the tank is ordered. What we can tell you is the envelope: a 60 inch circle, 63 inches tall, 182 pounds empty and 4,170 pounds of water when it is full. Run the volume against the system you are actually building in the tank sizing calculator, and take the general sizing logic from the tank sizing guide. For the wider question of how septic approvals and plumbing codes fit together across jurisdictions, the cross-border septic approvals and plumbing code article is background reading, not a statement about this part.
A pump tank among used oil tanks and a gravity feed system
| Part | Listed as | Length x width x height | Empty weight |
|---|---|---|---|
| SII-PT2S (this tank, septic pump tank) | 500 gal | 60 x 60 x 63 in | 182 lb |
| SII-5780100N97208 (gravity feed tank system) | 500 gal | 60 x 66 x 101 in | 305 lb |
| SII-5780102N95704 (used oil containment, level gauge) | 500 gal | 53 x 53 x 81 in | 280 lb |
| SII-5990702N95704 (used oil containment, level gauge) | 405 gal | 48 x 48 x 73 in | 250 lb |
| SII-5990902N95704 (used oil containment, level gauge) | 750 gal | 73 x 73 x 66 in | 300 lb |
Read this table as a volume band rather than as a family, because only the first row is a septic product. The other four are used oil containment tanks and a gravity feed tank system, and none of them is offered here for a septic duty; they appear on the sheet because they sit in the same size range. That is worth saying out loud on a page like this, since the one mistake that costs real money on a wastewater job is buying the vessel that fits the hole rather than the vessel built for the service. Among the three 500 gallon listings the differences are stark and they are all about shape. This pump tank is the shortest and by far the lightest at 63 inches tall and 182 pounds. SII-5780100N97208 puts the same 500 gallons into a 101 inch column at 305 pounds, and SII-5780102N95704 puts it into a 53 inch square at 81 inches and 280 pounds. Tall tanks buy head and lose headroom; this one does the opposite. The 405 gallon and 750 gallon used oil tanks bracket the band at 250 and 300 pounds. If you are shopping for a shop collection tank rather than a pump chamber, those rows are where to start and we will happily quote them; if you are building a system, this row is the one to be reading and the specification comes from your design, not from a table.

A twenty-four inch manway, a four inch inlet and a four inch outlet
- The manway: 24 inches, and it is the largest published opening in this whole batch. Twenty-four inches is a genuine access opening rather than a fill hole, which is what you want on a vessel that will be entered by equipment rather than by hand, and it is the dimension to check against whatever has to go through it before anything is ordered.
- What goes through it: the sheet publishes no pump, no float, no control panel, no riser and no lid extension. None is described here. What actually goes into the chamber is specified by the system designer, and the manway dimension is the constraint that specification has to respect.
- The inlet: listed as 4 on this sheet. The number is given as a bare 4 for the inlet and 4 inches for the outlet, and both are printed as the sheet gives them.
- The outlet: 4 inches. Every connection into a buried vessel is a joint, and joints are where a system leaks or lets groundwater in. Detail them, bed them and support them so that no line loads the tank wall as the ground settles.
- Plumbing discipline: the inlet, the outlet, the vent and the overflow are one arrangement and not four decisions, and getting the order of them wrong is a return visit. Settle that arrangement on the installation drawing before the excavator arrives, not at the edge of an open hole.
- Limits and term: 130 F / 54 C is the service limit, the highest in this batch, and there is a 3 Year Warranty. There is no specific gravity rating and no max contents figure on this sheet, so only the 4,170 pound water figure is printed.
One more time, plainly, because it matters more here than anywhere else on this site: this page makes no approval claim, no code claim, no burial depth claim and no traffic rating claim for this tank, because its sheet publishes none. Ask your local authority and your installer, and ask us for the manufacturer's own documentation rather than taking a product page's word for it.
Pump chambers, and what this page will not tell you
A pump tank is the part of a wastewater system that holds effluent until something moves it on, which is a different job from the tank that receives and separates. The buyers are rural and unsewered properties, seasonal cabins and camps, small commercial sites beyond a sewer line, mobile home and cottage installations, and contractors replacing a failed chamber on an existing system. What decides the purchase is almost never the tank on its own: it is the design, the site, the soil, the elevation the effluent has to be lifted to and the rules the county applies. We sell the vessel and we will quote the manufacturer's documentation with it; the system belongs to your designer and your installer. If you are comparing makers before you commit, the Norwesco versus Snyder Industries manufacturer comparison and the wider four-maker buyer guide lay out where each one is genuinely different rather than where the marketing differs.
One hundred and eighty-two pounds, shipped sixty by sixty by sixty-three
The plants listed are Chowchilla, California, Marked Tree, Arkansas, and Philippi, West Virginia, and the freight class reads LTL, a mode rather than a numeric class, under NMFC 156600-02. The shipping size is 60 inches long by 60 inches wide by 63 inches high. The sheet's Florida restriction applies to shipment as well as sale and use, and it is printed here as the sheet gives it. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. At 182 pounds empty this is the lightest 500 gallon tank on its own sheet and two people can move it on level ground, which is a real advantage on a rural site with no machine standing by. Take it by the body, never by the manway collar, and do not roll it across rough ground to save a carry. Check it over in daylight before it goes anywhere near an excavation, because the one thing you cannot inspect is the side of a tank that is already in a hole. Everything after that belongs to the installation drawing rather than to us. The last word on this tank is the simplest one: nothing on this page substitutes for the approval your county issues. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
