Hi, I have replaced my multiport valve last year due to the gasket seemingly melting into place, unable to remove anything more than bits and pieces. I just received the new valve, which came with a gasket, flushed the lines and went to check the gasket after and again, completely melted. Anyone ever deal with this? I am wondering if they came melted in, from being stored in a warehouse in the heat or something?Reply

john p - It sounds like the previous owner used the wrong glue when he replaced the gasket. You may be at the point where you have to buy a new Key Assembly that holds the gasket. See our guide on "How To Replace a Pool Multiport Valve Spring" This guide includes information on replacing the Key Assembly.Reply

I have Model SPO715G50M. I bought the kit to replace the o rings, but I cannot remove the spider gasket. This is the first time this is being replaced. Is it glued in?Reply
InyoPools Product Specialist Robert M. Posted: 10/30/2018
Hello PGB - Yes, the original spider gasket in the SP0715 valves is glued in place. Steps 4 & 5 explain how to remove the old gasket. We would recommend using an RTV silicone adhesive when you install the spider gasket. The spider gasket for the SP0715 valve is part number 4701-10.Reply

I did everything this guide said up until removing the old gasket. I physically cannot remove it no matter how hard I pull and I can’t upturn it with screwdrivers, pliers or any other tool. I’ve basically torn off a lot of the rubber but there is still so much I can’t remove. I don’t know if I’m doing it wrong or the original person who installed did it wrong. Please helPReply

Anonymous (handle won't turn) - The white plastic bearing washer underneath the handle may be broken. See our guide on "How To Replace a Pool Multiport Valve Spring" for instructions on locating and replacing this washer.Reply

I just replaced my gasket and now the handle won't turn and water is still coming out the backwash line while it is set to filter. Any ideas?Reply

I just ordered your Vari-flow 5 Gasket for my Pentair Multi-port Backwash Valve (27-1140) being run with a Triton Sand Filter and a Hayward pump. This is my second try so I'm just trying to get it right! Will this work? Thanks....Reply

O2Rocker - The plug is the upper part of the assembly that the gasket is set in. The intent here was to make sure you depressed the handle all the way down so that the gasket in the plug does not rub against the lower body of the valve while the gasket glue is drying.Reply
O2Rocker Posted: 7/2/2017
Step 9 says, rotate handle being careful not to rub plug. What "plug" are you referring to and how do you avoid rubbing it? Thx.Reply

nece - It is not absolutely necessary to set your MPV to "winter". Just make sure to line up the top and bottom of the MPV together correctly when reassembling the MPV.Reply
nece Posted: 6/16/2017
I do not have a winter setting on my valve. It is a Haward and looks identical to the one in the picture. What should I set the valve on when changing the spider gasket?Reply

Karen - Unfortunately, we do not sell replacement parts for the NE6170 Filter 6 Way Valve.Reply
Karen Posted: 5/12/2017
I need a spider gasket, but the only numbers I see on the filter is NF6170, it's a 1.5 hp blue wave sand filter, water leaking out of back wash, pool stays cloudyReply

Spider gasket - Inspect the gasket again for tears or breaks. Then try lubricating it. If that doesn't work try gluing the cross points on the gasket to the key assembly. don't use a lot of glue. And remember to turn the pump off before rotating the handle.Reply

Hi, I have only recently changed the spider gasket. About a couple of years. It still looks new. It has started to leak again from the multivalve. When I replaced the gasket before I did not put any adhesive or lubricated it.Reply

Backwashing without shutting off pump - There's a good chance that you have blown the spider gasket. Do you see water flowing or leaking out the waste line when the valve is in filter mode? Pull off the top of the valve and take a look at the gasket.Reply

Hello , my wife did a backwash without turning off the pool first, we have been losing a lot of water since. could she have broken a pipe somewhere?Reply
InyoPools Product Specialist Dennis R. Posted: 8/13/2016
valve leaking - It sounds like you have a spider gasket going bad. That's the only thing that controls the flow of water through the filter. Check the gasket for cracks and replace it if required.Reply

I have a sand filter and an inground pool.I turned off my filter, n switched to backwash to empty water from my pool. I then turned filter off and switched back to filter. There is still a little bit of water leaking from waste pipe it wasn't beforeReply

lesg - I could not find a match on FIMTA 50-90 v-w. Try matching your spider gasket to one of these listed in our Spider Gasket EZ Find list.Reply

Could you please advise?

spider gasket - The large hole in the spider gasket that takes up half of the gasket in used in all modes as the gasket is rotated around with the handle. See our guide on "How a Multiport Valve Operates II" for a more complete explanation.Reply

Is the lage hole in the spider gasket for the filter o the backwash?Reply

ronald - I'm not sure what the image you sent me is - http://imgs.inkfrog.com/pix/idrack/X5031-2.jpg. It doesn't look like the standard SP0714T MPV. Can you send me a set of pictures of the old Valve, top and side views? Can you measure the stem of the old Key Seal Assembly and the stem of the new Key Seal Assembly? Is your filter a sand or a DE filter?Reply
ronald Posted: 6/18/2016
I can't tell what make and model this multivalve assembly is? Mine is old and faded. http://imgs.inkfrog.com/pix/idrack/X5031-2.jpgI believe its a Hayward so I bought the replacement for the Hayward SPX0714CA Key Seal Assembly but the shaft is shorter so the assembly does not reach the diffuser (?) to make a seal. The shaft is shorter by about 1/8th of an inch.
thanks

Krissea333 - I 'm not sure why you removed the valve handle. You want to separate the valve cover assembly from the valve body by removing the 8 screws. See step #3. This will prevent any water flow to the gasket grooves and give you a dry surface to glue.Reply
Krissea333 Posted: 6/13/2016
I am trying to replace and glue the spider gasket but it seems that there is water still flowing after I remove the valve handle. It's not gushing but there is no way I can dry the groove to glue the gasket in. Do I need a whole new valve?Reply

TerryR - Take a look at the spring and washers on the valve stem. They may need to be replaced. See our guide on "How To Replace a Pool Multiport Valve Spring".Reply

I replace my gasket that comes as a hole now it's leaking thru the handle suggestions ?Reply

Pool Issues - Many manufacturers have gone to gluing the gasket in to keep the gasket from slipping out. They no longer sell the gasket by itself. If your valve manufacturer sells the gasket separately, slipping out might not be as large an issue. Some customers hedge by spot gluing the gasket at 3-4 intersections to help keep the gasket in place yet make it easier to replace later.Reply

Hello All, I've gotten mixed answers on whether or not to use glue for my new spider gasket on a Hayward sp715xr50.. Does anyone here know for sure? Thanks in advance.Reply
InyoPools Product Specialist Dennis R. Posted: 6/7/2016
Careless - It sounds like the spider gasket in you Multiport valve is blown and will have to be replaced. Depending on the manufacturer, these gaskets are sold separately or pre-glued into the Key/seal Assembly like this one. If they are pre-glued, you will have to by the assembly to replace the gasket.Reply
Careless Posted: 6/6/2016
I may have turned the multiport handle before the pump was completely stopped (not paying attention). There was a pop and now I can only use the filer port. I do not get any suction when the handle is on any port union except filter. Should I replace the multipart valve or could I have other damage?Reply
InyoPools Product Specialist Dennis R. Posted: 6/2/2016
Lynchrose - I'm not sure what multiport valve you have with your Jacuzzi Sandtrap filter, but this appears to be the key assembly that is used with the MPVs that mounts on your filter. If this looks like your key assembly, you are right. The spider gasket is glued onto the assembly and can not be purchased separately.Reply
Lynchrose Posted: 6/1/2016
Hi we have a Jacuzzi Sandtrapp St-24 filterI've noticed and all of the diagrams there was no picture of a separate gasket . Do I have to buy one pre-glued or do they sell the spider gasket separately?

hawaii pool - We sell your SP-715x62 MPV spider gasket separately which may indicate that it does not have to be glued in. When you take your valve apart, see if the current gasket is glued in. If it is, I would recommend gluing the new gasket in.Reply

How do I know if I need to glue the spider gasket in place?I have a Hayward SP-715x62. Does that require the spider gasket to be glued?
Thanks for any help.
