    Pressure Relief Valve for MasterTemp

    My plumber says a pressure relief valve is required by code for a new heater. I've read previous threads on this topic and understand the official Pentair kit is the 460925. But it's insanely priced at almost $200! I saw @ajw22 mentioned you can buy the parts separately at a plumbing supply...

    Help me fix my pool circulation during renovation

    See attached drawing! This pool was built in the 80s, and the locations of the returns has always seemed a bit weird to me. Circulation is a problem in a couple areas. Note: the prevailing wind is from West to East, but (a) there's a lot of variability from day to day and (b) the house is very...

    Air leak gets worse at lower pump speed

    I've been dealing with a small air leak in my system that I've been trying to figure out. This is on the deep skimmer line. I know it's the deep skimmer because I have check valves on all three lines (shallow skimmer, deep skimmer, main drain). The shallow skimmer and main drain check valves...

    How does poor circulation allow algae to grow?

    I've seen in lots of threads where people say that poor circulation can lead to localized algae growth due to lower FC in those areas. How does this happen? I thought Chlorine mixes pretty quickly, as shown in the dye video in Pool School. I'm not doubting that poor circulation is a problem...

    Safe to run old heater?

    I have a very old gas heater that I inherited with the house. The only thing I can read on it is "Laars 2" which, based on googling, appears to be a Jandy heater from 15-20 years ago. I know the heater was tested last year by the pool company the previous owner used. So it still worked as of...

    Bubbles in check valve

    With TFP's help, I was able to open my pool this season by myself! Feeling mighty proud. :) Thanks to all who contribute here. Now I'm onto fixing a suction side air leak problem. I have three lines that go to my pump: the main drain, shallow skimmer, and deep skimmer. All three of these...

    Solar cover only (no heater)?

    I'm planning to renovate my pool soon and need to come up with a heating plan! As part of the renovation, I'm hoping to move the equipment pad down closer to the pool. But space is at a premium and I'd rather not have a big honking heater there if it's not necessary. My current heater is also...

    How do I install my new pump?

    My pump kicked the can last week, so I have a new Calimar pump on the way (1.5 HP since the 3 HP is out of stock). However, I'm new to this whole pool ownership game, and it seems the previous stewards of the equipment pad didn't leave me with a lot to work with. See attached photos! You can see...

    Pump died, need help! New pool owner

    Welp, I think my pump died today. RIP. It started making a high pitch noise last night, so I turned it off. When I tried to prime it today, it started making a terrible and loud screeching noise. I'm not really interested in trying to fix it since it's 10 years old and single-speed, so seems...

    Is this normal? Dolphin Active 20 leaving debris

    When I run my new Dolphin Active 20 for a full cycle, there's still quite a bit of debris left at the bottom of the pool. Photos attached. Is this normal? I previously had a very old pressure side Polaris that I was excited to upgrade away from. It got stuck on the stairs constantly and the...

    Jandy 3-way valve installation quick questions

    I'm installing a Jandy NeverLube three way valve (part #4715). Here are the installation instructions. 1. The instructions say "The internal valve assembly must be removed prior to gluing valve body to pipe fittings. Make certain no glue enters valve body beyond ports." Is it really necessary...

    Little bugs after adding dry acid?

    First of all, I know dry acid isn't a favorite around here. I'm a new pool owner and already had the Clorox pH Down before I discovered TFP, so please go easy on me! I'll switch to MA after I use up the bag. Anyway, my pH was running a bit high so I added some of the dry acid yesterday and that...

    Newbie installing a filter myself: plumbing size?

    Hi everyone! I'm a new pool owner and have been using TFP with great success for balancing chemicals. Thanks so much to everyone who contributes here. I just purchased a Pentair CCP 320 filter to replace an old filter from the 1980s that is causing all sorts of problems -- leaking, shooting DE...
