Hi, Bob. The Air Bleed Valve is located on the bottom right of the pump connection port on the valve.

I'm in the SD 80 thread and considering if I should replace the whole filter. I I'm hoping you could give me an estimate of flow rate. Hayward Super Pump II, A.O. Smith 1.5 HP Round Flange 56J Dual Speed Full Rate Motor - B2977, 2" lines, about 84 ft to skimmer

Hi, Rick. Using the info provided I'm unable to provide you with flow info. If your pump still works, you can use our How To Measure Total Dynamic Head With Gauges guide to calculate your head. Once you get that we can provide you with the data.

I have a SD 80 and replaced the sand a year or so ago. Started up this year, backwashed and then a sound and now sand blows back into the pool. I suspect a cracked lateral or standpipe. BUT when in recirculate mode, water slowly leaks out the backwash pipe. Perhaps some thing with the 6 way valve?

A  Answered on 3/19/2019 by InyoPools Product Specialist Lennox H.

Hi, Rick. You do have an issue with either the standpipe or laterals and the valve. You may need to overhaul your filter based on how old the filter is. Use the Replacement parts for Pentair Sand Dollar Filter link to locate the replacement parts for your model filter.

    This is for the Sand Dollar SD 80 thread. Can the multi valve be rebuilt? I've pulled the valve, no obvious external damage but when on Recirculate mode a stream of water the size of your pinkie finger comes out the outlet.

    • Commented on 3/22/2019 by InyoPools Product Specialist Lennox H.

      Hi, Rick. You can rebuild the valve using the Top Valve Assembly - 272531

We just replaced our old filter with a new Pentair SD80. I need a fitting for the diverter valve for the waste hose. Do you sell those? My old filter only had 2 hookups for the hoses. The backwash hose was smaller & held on with a clamp.

A  Answered on 8/3/2018 by InyoPools Product Specialist Hector F.

Unfortunately, we do not carry those types of fittings but what you can use is an MIPT x Socket fitting that you can locate at any local hardware store. Just match the diameter of the discharge port on the valve to the male side of the fitting. 1.5 or 2 inches are the most common.

what is winterize setting for

A  Answered on 12/6/2017 by InyoPools Product Specialist Kevin G.

The winterize setting closes the valve off so that no water can get into the filter.

I have a Pentair SD-80 pool filter and I am seeing a decent amount of sand returning to the pool. What causes this and more importantly, how do I fix it?

A  Answered on 6/25/2017 by InyoPools Product Specialist Hector F.

Very often the cause of this issue is that the laterals and or standpipe in the filter have gone bad. We recommend to inspect those parts and also inspect the multi-port valve gasket as well for that can also contribute to the issue. 

?     Asked on 5/21/2017 by Mark

I have a SD 80 and it is leaking around the handle. I am going to replace the multi port valve but I see it has 1.5 inch ports and all of my pipes are 2 inch. Did they over pipe for the SD 80? I appreciate any help.

A  Answered on 5/24/2017 by InyoPools Product Specialist Lennox H.

Hi, Mark. Use the info in our PVC Pool Pipe Dimensions to confirm the size of your plumbing. If you do have 2" pipes then you will have to use a reducer fitting to go from 2" to 1.5".

Hi, We have a hairline leak in the seam of our SD80 tank. It's almost 4 years old. This appears to be a common issue with this unit. Before I replace it, is there any measures I can take to prevent this on a new filter?Also, is this the average life we can expect on it? If so, are there any others on the market with a better expected lifespan?

A  Answered on 4/14/2017 by InyoPools Product Specialist Scott W.

I see the hairline cracks and leaks mainly when the filter is not sized properly and cannot handle the flow rate that the pump is pumping out. What is you pump model and the distance from your pump to your skimmers so I can calculate your flow rate?

?     Asked on 2/14/2017 by Stephen

I have a 3 year old Pentair SD80 filter that has developed a crack in the seam and is leaking water. Is there anyway to correct this without replacing the filter?

A  Answered on 2/14/2017 by InyoPools Product Specialist Lennox H.

Hi, Stephen. Repairing the tank doesn't always hold up, we recommend replacing it.

?     Asked on 7/14/2016 by Tracy

We have a Pentair SD80 filter that has developed a crack in the seam. Can we replace with a Hayward S244T model ? We have a 26,000 gallon in ground pool.

A  Answered on 7/14/2016 by InyoPools Product Specialist Alan M.

You can absolutely replace the SD80 with the S244T. You would most likely need to do replumb the piping, but the the filter is enough to filter your pool adequately.

?     Asked on 6/30/2016 by Jim

What size filter for 26,000 gallon pool. I am getting ready to order one. Thanks

A  Answered on 7/2/2016 by InyoPools Product Specialist Megan C.

Hello, Jim. The SD-80 Sand Dollar W/ 6 Way Valve PART#145333 is a great choice for your size pool. It is best to check the flow rate of GPM (Gallons Per Minute) that your pump provides, to ensure it does not exceed the design flow rate for this filter, which is, 75GPM.

A  Answered on 6/16/2016 by InyoPools Product Specialist Lennox H.

Hi Jerry, The 1 1/2" Top Mount Valve Flanged-262506 is the control valve for the SD80 filter.

?     Asked on 5/16/2016 by

What's the difference between SD-80 and the TA-60 and which would you perfer?

A  Answered on 5/19/2016 by InyoPools Product Specialist Lennox H.

Hi, The SD-80 is a higher capacity filter than the TA-60. The two unit also have a dimensional difference. The bigger the filter the better so I would go with the SD-80.

?     Asked on 3/30/2016 by SaraNjoe

Is the sd80 one size? 36" or does it come in different sizes. Thanks

A  Answered on 3/30/2016 by InyoPools Product Specialist Megan C.

Hello, Sarah. The Pentair Sand Dollar Filters are offered in five different sizes. The Model numbers are SD35, SD40, SD60, SD70, and the SD80. They also offer a Special Order item SD80 2" part number 145386. If you need a 36" Sand Filter I best recommend the Triton II TR140 MODEL# 140243 Side Mount Sand Filter with the 2" High Flow Multiport Valve w/ Plumbing (sold separately) for Triton & Quad DE Filters PART# 261050.

Hi, The multi-port valve on the Pentair Filter - SD-80 Sand Dollar W/ 6 Way Valve will be labeled "PUMP" for the inlet, "RETURN" for the outlet and "WASTE" for backwashing.

I would like to know if the filter price includes the sand. Thank you

When should I change the sand in my filter?

A  Answered on 1/27/2012 by InyoPools Product Specialist Patrick P.

You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.
