One of the most common problems pool owners run across when maintaining and serving their swimming pool is a leaking backwash valve. The backwash valve is the valve which is mounted on either the top or side of your filter tank and are specifically used clean sand filters or DE filters. One of the most popular filter manufactures in the world is Hayward Pool Products who also makes quite a few backwash valves. Based on the Hayward valve you have the fix varies slightly. This guide will help you determine which Hayward valve you have and then determine the proper fix for your situation.

I have replaced the whole valve with a new one so .ca my old one I couldn't replace the o ring and the other gadget. But I noticed my back wash is not coming out like it use to about half as much water comes out.Reply

Fred - Sorry, I can't find Spo714g11 in our system or the internet. What filter is it mounted on?Reply
Fred Posted: 6/8/2017
My part number is Spo714g11?Reply

My Hayward Multiport Valve also has only SP71 on the label. No additional number is available on the handle or along the valve body. Am I missing something?Reply

Sean - SP71 is the first part of several Hayward MPVs. I would have to know the rest of your part number to know what gasket you need. If it is the common SP714T MPV, you would need the whole Key/Seal Assembly. The gasket is pre-glued into the assembly and is not sold separately.Reply

I have a hayward sp71. Which gasket do i need.Reply
InyoPools Product Specialist Dennis R. Posted: 6/1/2017
Greg - If you replaced the handle/valve assembly, you replaced the spider gasket that comes with it. A damaged spider gasket is generally the culprit is water going the wrong way. Look at your new spider gasket for any new damage. If it looks good, check for cracks in the valve body.Reply

SP714A is the part number for just the valve body. SP714T is the part number for the entire valve.Reply

I have a SP714-A. It is stamped on the body molding of the unit.Reply

Anonymous (leaking MPV) - The appropriate fix for a leaking SP0714T valve would be to replace the diverter (part # SPX0714CA) which comes with the spider gasket glued into it. This is an easy enough fix, you would just need to remove the cover and handle assembly from the current valve and swap out with the new diverter. See our guide on "How To Replace a Pool Multiport Valve Spring" for instructions on removing the diverter.Reply

Lisa - The spider gasket for your SP740DE multiport valve is SPX740D.Reply

SP714 is the part number on the multiport valve. It is leaking in the filter position and even when closed is leaking slightly. Please recommend replacement part and how I can order.Reply
Lisa Posted: 4/27/2017
I have model #SP740DE,what should I use?Reply

Eric - If a gasket has to be glued in, it is only sold as a part of the key assembly like the SP714. The SP715 gasket is sold separately so does not have to be glued in. However, many people put a drop of glue at a couple of the gasket intersections to help minimize gasket movement when rotating the handle.Reply

Does the spider gasket for my Hayward SP 715 require Loctite when I replace it? It seems that some spider gaskets do and others don't and it's not clear to me.Reply

Ron - I'd take a look at the spider gasket inside the multiport valve to see if it has been damaged. See our guide on "How to Replace a Spider Gasket on a Multiport Valve". To find out what model MPV you have, find the model number of your filter and see what MPV is associated with the filter.Reply

I have a leak in my Hayward flush valve. It started with the valve being difficult to turn. Recently, I discovered ball bearings in pump filter basket which I have no idea where they originated. The pump seams to be operating fine. The real clue to back flush leak was when the pool level dropped. Where should I start first? Is it repairable or should the whole valve be replaced?I can't find a model number on the body or handle. On the label, very deteriorated, only thing I recognize is the 50 PSI and the 75 GPM flow.

710 flovalve - It sounds like the spider gasket in your flovalve is damaged. See our guide on "How to Replace a Spider Gasket on a Multiport Valve" to see how to inspect and possibly replace your spider gasket.Reply

I have a hayward flovalve the # on the top is 710. It's leaking while it is in the filter modeReply

Leaky MPV - If you are holding down the handle to backwash, you are allowing waste water to go out the return port as well as the waste port. This also might have damaged the spider gasket. See our guide on "How to Replace a Spider Gasket on a Multiport Valve" to see how to inspect the gasket and replace it, if required.Reply

I replaced the entire valve however water still dripping and cannot get it to backwash without holding down the handle. Any suggestions?Reply
InyoPools Product Specialist Dennis R. Posted: 9/10/2015
chefd55 - It sounds like someone has over tightened the screws and damaged the lower valve body like you described. You might check to see if the o-ring between the valve cover and the valve body is there and not damaged. Like #6 in this list of valve parts. Note: this may not be your valve. If the o-ring is good you will probably have to buy a whole new valve. Replacing just the valve body will cost you more than buying the whole valve. To replace the valve you will have to cut out the current valve and glue in a new valve. Not a hard job but may be tricky the first time.Reply

The leak seems to be coming from where the bolts are connected through the holes. Small cracks around and under the edge of the plastic body (casing?)where the valve is connected with the bolts.I've tried things like epoxy, pvc cement. Was gonna try liquid nails?
Do I need to buy a body, or housing, or casing whatever it's called? How difficult is it to change this whatever it's called, or do I have to call a plumber? It doesn't look that difficult.
Thank you

cindi - Here's the label plate for your sp-0711A13 side valve.Reply
InyoPools Product Specialist Dennis R. Posted: 5/21/2015
cyndi - This should be the spider gasket for your sp-0711A13 side valve. Check the number of spokes and other dimensions to be sure.Reply
Anonymous Posted: 5/19/2015
Can I buy a new label for this also?Reply
cindi Posted: 5/19/2015
Label is gone found a sp-0711A13 on the side. Can I replace the spider gasket on this? Leaking from back was.Reply

Dave Thompson - If your pump is over 10 years old, you might consider replacing it, but most people just replace the motor. If you're comfortable with fixing things, you shouldn't have any trouble replacing a motor. See our guide on "How To Replace the Motor on Your Pool Pump" for step by step instructions on replacing a typical pump motor.Reply

My swimming pool pump has been acting strange lately. Should I look into getting it replaced, or do you think it is a problem I might be able to fix on my own? I am pretty good at fixing things on my own, so I feel confident I could do a pretty good job. http://www.globalrewinds.com.auReply

ataylor - I suggest calling Hayward on this one at 866-772-2100. I am not familiar with this problem.Reply
ataylor Posted: 7/21/2014
I purchased the replacement Key/Seal Assembly (Diffuser w/ gasket glued in) (spx0714ca) However, the old diffuser had a gasket on the top of the piece as well as the glued in gasket on the bottom. I removed the top gasket from the old diffuser which appears identical to the gasket slots in the new diffuser except that there is an inside the gasket ring a perimeter wall which precludes the installation of the old gasket. What now?Reply
