This guide describes the steps required to install a Hayward sand filter. The picture at left shows the two major components of a typical sand filter: the Filter Tank and the Multiport Valve and piping assembly. When installed, the valve sets on top of the tank and the vertical pipe the lateral assembly are inside the tank.

After numerous people telling they would do or help me do it, I'm doing it myself! I have a hayward pump and a sand filter that was given to me without the top and cleaned all the sand out. Went and bought a used top for the sand filter and now after looking at your site and instructions I'm wondering about the piping, it didn't come with any. I'm using this filter for an above ground pool. Any suggestions?Reply

Excellent guide. The instructions that came with my new filter said nothing about taping the top of the laterals pipe but I did and there was a mountain of sand that the tape kept out! Also, I had a very small drip drop from the pump inlet. I redid the teflon tape (as you suggested) 5 times instead of one & that did it!Another commented said he had a problem centering the laterals pipe. To avoid that problem, I rotated the cardbord guide to make sure it was centered in all directions and it lined up perfectly.

sand filter not working - Sounds like you have one or more leaks in your system. Look at you How to Guide on correcting pool leaks (under the pumps section of How to Guides). It will give you some places to look.Reply

Jim - Try wrapping 5-7 layers of tape around the fitting. If that doesn't work, you may have to replace that fitting. If you have enough length in the pipe to your union, you can cut into that pipe and use a straight coupling to replace the pipe and fitting to the filter.Reply

Thanks for posting these instructions. I have installed my sand filter but am having a problem with Step 16. The adapter in the Pump port keeps leaking. I wrapped it several times with teflon tape. This is the second time I've done this and it continues to leak about 1 drop every 8 seconds. Any suggestions? Thanks in advance.Reply

Filter blowback - Check to make sure your spider gasket is intact. Make sure you have at least 6" between the top of the sand and the bottom of the valve. I am working on a site that show pictures of multiport labelsReply

I have a sand filter but it is not work properly. The pump is fine but I lost my pressure. The pump is reading 10-15 psi. Also the sand filteris leaking, I have no pressure coming out of the return valve and very little sucuction from the pool. What do I do?Reply

I am having the same problem as Mary Harrison did in 2011 comments. My filter is blowing debree and some sand back into the pool, the water is crystal clear. We have 5 new laterals this year. What is going on. Also the name plate on the top of my filter is shot and I can hardly tell where everything is, ie, filter, backwash, etc. urgggggReply

rjb - If you can gently nudge the central pipe to center without lifting the assembly off the bottom, try that. If it comes off the bottom, you will have to remove the sand and start over.Reply

I'm helping a neighbor replace the sand in his very large pool filter. We followed all the steps in your diagrams, however after the sand was replaced, we are having difficulty getting the control valve to seat on the central pipe. We took care to center the pipe while refilling, but it appears to be slightly off center. Any suggestions?Reply

Our label on our Pentair Sand Filter is missing and we don't know where anything is...it's an SD40 model. Please help!Reply

Patrick - You are going to want to replace the cap so take the cap to a hardware store and see what male threaded fitting can attached to the cap. Once you find fitting take the cap off and find the female fitting that can be screwed on the first fitting. This second fitting is the one you want. It will screw on the threaded port on of the drain. The other end of this filling should be a slip end for a 1 1/2 inch pipe to slide in and be glued. I would now put a 1 1/2" union onto the pipe so you can later detach the drain from the drainage pipe if you have to work on the filter.Reply

Thank You so much for this information.Reply

Liz, It's hard to say without seeing the valve. It sounds like you have a blockage in the top of the valve. If this is a new valve, you may have a bad valve. You may have to have a pool professional look at it.Reply
Liz Posted: 7/12/2011
Thank you so much for the great detailed directions. I did everything exactly as told and the filter runs great but I don't get any pressure when I try to backwash or vaccuum to waste. The water just trickles out. What is wrong? Please help. ThanksReply
Lisa Posted: 6/17/2011
I would not have been able to "easily" install this filter with the instructions provided by Hayward. Your step by step details with photos were awesome. They should pay you a comission off what I just paid them!Reply
Mary Harrison Posted: 6/9/2011
Our sand filter is blowing some sand after we backwash it. It is also blowing back into the pool some of the particles that have gone through the filter system. What in the world do we need to do? The water is clear as crystal.Thanks,
Mary Harriston

We have a sand filter and it seems that half to 2/3 of the sand has gone into the pool. We took the filter apart, checked the laterals and found no holes or cracks. The top section for Filter, backwash, etc. has been replaced by a pool co. (not sure it solved any of the problem). My question is once we put the filter back together and want to clean the sand out of the pool, what settings should be use and for how long to get the sand out?Reply
mark Posted: 5/13/2011
Should the laterals with the downpipe be all the way at the bottom of inside of filter when filling sand or should it be up a few inches from bottom, since it is actually a few inches above bottom when inserted into the valve assembly. ALSO, it appears from all instructions that the top of the lateral downpipe is NOT glued to the valve assembly, it just slips in (correct?).Reply

was given a disassembled used sand filter...soo info helped alot. thanksReply
InyoPools Product Specialist Dennis R. Posted: 3/21/2011
You should leave a minimum of 6" space between the top of the sand and top of the tank. A couple of inches more space is all right. 3 bags is the recommended amount for the Hayward S180T filter. Other size filters will take more or less sand.Reply
dagie Posted: 3/19/2011
I put in the recommended amount of sand (300#), but it didn't come to within 6in of the top...is that OK?Reply

We know of no unique unions that connect directly to the multiport valve. The multiport valve will install on a DE pool filter much like the Sand Pool Filter with short pipes and standard unions.Reply
Chuck Posted: 10/4/2010
Thanks for the helpful information. Is a DE filter connected in a similar manner adding unions? Are there unions that can be connected directly to the multiport valve? Thanks.Reply
