Multiport Valve Filter Setting Issue..Water Coming Out Of The Backwash Hose..
Question 2 Question 3 I have a Hayward S244T top mount sand filter. Today I vaccuumed to waste, finished, turned off pump, changed setting to filter but water is still coming out of backwash/rinse hose. Water is coming out of jets in pool, but also the hose when in filter setting. What can be causing this and is it something I can fix? The pool was operating normally prior to vaccumming to waste. Could it just be a bad seal? Thanks for the question The multiport valve sounds like it's not closing off at the waste line. If it doesn't "click" into place the gasket might be going bad or is already worn down. There are a couple of reasons why you're having water leaking out of the backwash hose: * The spider gasket has gone bad or is crusted up * The compression plate and compression spring might be going What I've found is that it's normally the spider gasket. When it's replaced your problem should be solved. By adding a valve to your waste line, this may stop the water from leaking, or stop the water loss completely, but it may cause your filtration to be reduced and you'll have problems later on. Below are a couple of pictures for a spider gasket for multiport valves.
It's a pretty simple operation, but take care in remembering how you take the screws out of the multiport valve. Hope this helps and good luck with your pool.

Robert New Question: Valve Works In Every Position Except Backwash Date: Jun 15, 2011 We are on our second multi port valve and 3rd spider gasket and second spring. The valve works in every position except when put in backwash. The pressure of water backwashing is low and there is water returning into the pool via the return jet. Answer By: Robert Date: June 15, 2011 Thanks for the question I'll first direct your attention to this post: Sand Filter Works But Will Not Backwash It has a little more information. Without actually seeing the Multiport valve, or your operation of the valve, I will try to give you a few more troubleshooting tips. Check the spring under the handle. You may be able to replace the entire handle for around $40. If you're turning the handle while the pump is running, this could be your problem. Be sure the pump motor is turned off before adjusting any valves. The gasket/handle/plate may not be aligned properly. The spring may not be not pressing the diverter plate down firmly enough on the gasket. If the valve is sticking, this is the earliest sign of a problem. Sticking means that the valve is in need of lubrication. Be sure to not operate the pump with valve in the CLOSED position. Be sure the part you took off to get to the gasket is put back on correctly. You'll need to use a special glue to hold the spider gasket in place, and lube it well. Some good glue and lubes are : Aqua-Lube Jack's Lube Pool Filter Multiport Valve Gasket Sealant Pool Filter O-Ring Gasket Valve Lube Sealant 1.75 Oz bottle. Hope this helps and let me know how it turns out for you. Robert Comment: Help By: Cindy Date: July 29, 2011 When we backwash the water still comes out of the hose for backwashing.
