Title says it - gotta replace a very old booster after already replacing the very old vac. Vac is a polaris TR28P (been very satisfied with it so far, it does did a great job with pine straw, before the pump eviscerated itself). Polaris recommends their PB4SQ booster. Claims of efficiency...

If this is the wrong place to post this please let me know and I'll be happy to move it. I made several efforts to save my Minimax NT 400 and all I have to show for it are some new parts. They are very lightly used since the heater only lasted about another month after install. They're...

Replacing minimax NT 400 (400k btu) and going with RayPak low nox heater. There are two options and I am hoping to get some advice about which to choose. I can either get the ASME model that has copper heat exchangers, or go with the cupro nickel heat exchanger version that is NOT ASME. I...

This is not a solicitation for recommendations of any particular model - I understand that models need to be selected specifically to handle the pool size/region/etc/etc/etc. If my prior posts are any indication, I've met my match when it comes to our very old MinimaxNT and have decided that...

I imagine the answer is always going to be that anything is *possible*, but I'm wondering more what's practical or efficient. I've included a (very professionally drawn) picture of the roof, equipment location, and usable roof space. Equipment circled, red line to house represents about 40...

I've got an old Pentair Minimax NT that I've dumped a modest amount into reviving, and it's worked for a while until now and I'm totally stumped. Heater worked fine the first two years we were in the house. It had some issue come up that led me to open it up and discover just a ton of rust and...

UPDATE: Found a post from Feb 2013 on whatthebest-hottub.com referencing the K10 relay on a Sundance spa. Apparently not a terribly uncommon failure that many folks fix by purchasing a new circuit board. HOWEVER, there's a way to wire the circ pump to another relay by switching the terminals...

TL;DR: is it possible that my E04 code is being caused by the gas manifold simply falling out of place causing the burners not to ignite? So far, propping up the manifold (where it normally falls open because its screw hole is rusted) seems to be all that's needed to fix* my annoying E04 code...

Nothing's broken, everything works, salt level is 3200. But it made me wonder, what would happen if my salt level was twice that? Would the salt deteriorate the pool? The plumbing? Would the chlorine generator still make chlorine? Would algae, etc even grow in that?

I've got a buzzing flow motor and a "FLO" error on a spa. I switched out the capacitor with one that I have not been able to test yet, so I can't vouch for it, and I get the same buzzing. I can't take a cap off of either of the other motors because the covers are sealed shut. Obviously it's...

Currently have a Hayward Aqualogic PS-4 (SWG, looks like this one ). I've been reading a lot about the apps and home automation related resources with pools and spas and was wondering if there was any way to retrofit any kind of automation or wireless/phone based control to this kind of system...

Current pool pump is a Pentair WhisperFlo 1.5 HP single speed. For all intents and purposes the pump is fine but the motor is showing its 7-year age. (1) Can I replace just the dying single-speed motor with a variable speed motor? (2) Is that even worth it, or does replacing the whole pump...

'06 Sundance Cameo main fuse blowing Got home from vacation to find no pumps or filters running. Checked and the breaker was tripped. Flipped it on and noticed the same except also my control panel going a bit berserk, though not showing any actual codes. Flipped breaker off and on once more...

Bit of a newbie here - 23,5K gal shotcrete pool, water is in balance and the dead salt cell has recently been replaced and is up and running (YAY!). With everything now in place, I'm taking over the cleaning from the pool company. That currently entails skimming the surface, cleaning the...

Hot tub is 385 gallon, around 94 degrees (if that matters). Fresh fill on Wednesday readings are the readings for our tap water. Fresh fill on Wednesday: - FC:1 pH:7.5 CC: N/A TA: 30 CH: 40 (This is before adding anything) Added 1oz dichlor and 1.5 oz baking soda the next day: - FC...

New-to-me pool owner, came here and did the following: bought a K-2006 test kit, set up a spreadsheet, tested my water basically every other day for the last week. Here's where I'm at after a few days: FC pH CC TA CH CYA 1.6 7.6 N/A 100 ~220 ~45-50 11 (shock) 7.6 N/A (shock) 100 3.0...

Got a Hayward Turbocell T15, freshly cleaned. Maybe 5 years old, maybe older. Maybe younger. (Just bought the house and didn't get those details. :brickwall:). Cell is clean, free of all scale, hooked up, and system is running. Problem is, I have no idea how to know whether things are...
