I think I have my robot choice narrowed down to the Maytronics M400 or the Polaris 9450. I was at the local store last night, and the big, single filter basket in the 9350 is making me want to buy it no matter what. The guy at the store that actually works on all these things said the...

I don't know if the sequence of events is important, but here is what happened: For the first time since having VS pump installed we had a freeze. Since our old freeze protection unit was not bypassed, the low flow of the pump is causing the heater blower to kick on and it cannot be turned...

I've got a Hayward Super II with a 2HP motor. Both were in place when buying house 7 years ago; no idea how old they are. The pump is leaking from somewhere underneath it, and occasionally from the top, between the pump housing and motor. I've replaced the ceramic seal as well as the ribbon...

For some reason when I heat up our raised, attached spa, the water becomes cloudy. It remains clear if I run it without the heater. Does this make any sense? If I look carefully, it looks like tiny white particles floating around, which I assume is DE?? I picture the inside of a heater...

I replaced all my grids and now several months later I'm getting DE all over the place. I may have screwed up by not replacing them all at once, as I tried to guess which ones were leaking since I couldn't find any holes and only replaced 5. When it still didn't seem to be filtering very well...

I am a research freak and would REALLY like to avoid my typical pattern of days of reading and analyzing since I was coming home from work this morning and could hear my pump from about 250' away. Hopefully you will bear with me, as I have several questions after reading all the posts I could...

I have a Hayward astrolite fixture in which I replaced the bulb with a Colorsplash 3G bulb. It worked fine for several months and then began to malfunction. It turns out that the fixture was leaking and caused a short inside the bulb. I can't believe the GFCI never tripped, as it was about...

Everytime I've removed the clear cover on top of the pump strainer basket its been extremely difficult. I've replaced the o-ring, lubricated the heck out of it, and been careful not to overtighten it (at least I thought)! I'm wondering if this is normal, and if anyone has any ideas on how to...

I drained my inground pool today below the level of the light, and its been draining water for over 12 hours. You cant actually see running or dripping water, but the wall below it is constantly wet when everything else is bone dry. If I remember correctly, it did it for DAYS when we had it...

I just drained all but about 3 or 4 feet of the deep end to polish the horrible stonescapes finish we had put on (bad application, not product) and have a few water questions. I've never drained and started with new water before and am wondering if theres a way to guess at the stabilizer I'll...

I've posted in the past during a pool renovation regarding crack repair and got lots of good info, but they came back. I repaired the top of the crack (all the way up to the tile!!) with the two part putty, and it held great, but its dark blue on a stonescapes finish and it will look terrible...

I'm installing an in-line chlorinator that states I need a check valve to prevent corrosive backflow if I have the following: -preceding valves constructed of PVC or other plastic with metallic shafts -heaters or other items with metallic tanks, shafts, coils, or tubes. unfortunately, I don't...

Our piping around the heater/pump/filter is absolutely ridiculous with the number of elbows, turns etc. I am sure Im losing pump efficiency due to friction loss, and want to replace it. My question is, can the valves possibly be saved, or is the PVC glue going to make it impossible to reuse...

I've got a Hayward Navigator Ultra that came with our house, so I have no instructions, video, tools, gauges, or anything to adjust it with. Does anyone know where I can find this info? I've looked all over the internet, and can't seem to find anything relevant. This thing is so finicky, its...

We have a hayward navigator that is okay but needs constant babysitting and its driving me crazy. I'm wondering if a robotic cleaner will work as well as a suction side cleaner since our main drain is not functional. My reasoning is that without a drain, a suction cleaner is the only thing...

I backwashed our filter today, and after returning the haward vari-flo valve to the filter position, it seemed to be working fine. Later, I happened to be in front of the house where our backwash piping dumps into a storm sewer, and there was still water coming out. I went back to the pump, it...

This will be our first winter as pool owners, and I was wondering if the pump needs to continue to run as often with colder temps and no swimmers. It ran about 8 hrs/day in the summer. I realize leaves will be an issue, but other than that, would a few hours a day be okay? Also, with water...

We had a replaster done that involved some crack repairs, and one of the worst ones is already coming back. We used a dark pebble plaster, which should hide it a little better. Can anyone suggest a product that would hold up underwater and dry clear to seal a crack? 3M makes some really good...

Our air temps are still very conducive to swimming, but the pool is starting to get pretty cool, and I'm wondering if the solar blankets do very much to warm the water. If they do, is it too much of a hassle to take them on and off?

Our pool remodeler had to drop our ph way down to try to get some remaining scale off our pebble finish, and I am trying to get the pool usable quickly. My question is, will baking soda bring pH up immediately, or does it need to circulate for a while? I added about 11 boxes already and its...

I've been buying 4.2G of 6% bleach at Sams for about $7. I'm in the Dallas area and was wondering if thats reasonable. I can't help thinking there must be an industrial supplier that sells to laundromats, dry cleaners, or restaurants where I could buy in bulk. Anyone know of anything like that?

I currently have a Hayward Navigator suction cleaner that works pretty well, but is a HUGE pain for me. I was pretty much set on going to a pressure cleaner, but have a few reservations. One is that our main drain does not work, so the suction cleaner running water through the filter is a...

I'm using bleach now for both maintaining levels as well as shocking, but it sure would be easier to have a big bucket of shock around! I've read the labels over and over and cant find out whether there is CYA in the granules as in the tablets. If it is in there, will it increase the levels...

Not sure if this is the right forum for this, but couldn't find one more appropriate? We have a retaining wall around our pool that has a ton of cracked mortar joints. I know nothing about masonry repair so I don't know if its even worth fixing, but it seems like it will keep getting worse and...

I'm only about 4 months into the pool-owner thing, and have a question about excessive rain. We've gotten flood-level rains over the last two days, and even our coping is underwater. I realize its going to throw off the chemicals, but do I need to pump it out to waste, or can I just consider...

We just had a remodel done with Stonescapes Tropics Blue mini pebble. The slope to the deep end and part of the deep end itself has some major "splotchy" areas, as well as dark lines in a few places. I know others have said that these type finishes take a little while to reach their final...

We just had a remodel done, and I'm trying to get our chemistry in line. I have read and read these posts about water chemistry and thought I had it down, but still have a few questions. Is there a proper sequence that is ALWAYS the right way to bring the different parameters in line, or...

I have a suction side Hayward Naviagator that I'm thinking of converting to a pressure side Letro or Hayward Phantom. My question is, do the pressure cleaners send water to the filter, or just through the bag attached to the cleaning device itself? I'm thinking that the pressure cleaners would...

We're trying to choose new coping for a pool remodel that will probably include a salt system. I've heard all the horror stories about the salt tearing up flagstone, limestone, etc. Does anyone know if certain types of stone are more dense, or otherwise resistant to this problem? We are...

We've had several bids on a total pool remodel, including the repair of several cracks. About half use epoxy injection, which is VERY expensive, and the others had various other ways to patch them. Some that used to use it have even stopped using the epoxy since the pool will just crack...
