Bottom, Tank SBMW 4000 - 197130
The bottom tank of my Pentair 147411 SMBW 4060 Sheet Molded Fiberglass D.E. Filter Tank with Valve has a crack and is leaking profusely. Are all my fittings, manifolds, and valve easily re-installable if I purchase a replacement bottom tank from you? Are your parts "New" Thanks for a speedy reply. John Hawes drbeejer@earthlink.net

Hello John. The parts are indeed new and from the manufacturer. As far as how "easy" it will be, I can say that the parts will fit on the new bottom. The ease may be the part in question, but they will fit.

Hi! I have a pentair swbm 4024 de filter. The Rotory valve for backwashing has cracked at the copper fitting for the slide handel. I purchased a new one unfortunately it had a bad cage seal & it bound up when we installed it. Also Part of the problem I am having other than needing a new seal is...what do you do to get the Rotory to turn free? I put o-ring lube & it made it worse. I even tried cooking spray (haha) better result. So what do I need to do when I replace it to get it to slide free?

If the rotor valve was replaced then yes we believe the seal is bound up. If the seal got/ is damaged get part # 071720, if it is not damaged put it back in place & use Magic Lube since you used cooking spray that WILL deteriorate the seal we recommend you replace the seal again.

I did replace it...But there turns out to be a big problem with (the smbw 4000 series, & any installed before 2005ish). The manufacturer reformed the cage style seal on the rotary valve to be tapered. Older units are STRAIGHT, & will not take a tapered seal!!! Mine #4024 and #'s 4036, & 4060. All have straight formed filter bases, tapered will not work!...It cuts the seal. Which is what happened. Unfortunately I know 4024 & 4036 are discontinued models. I bought another. But still need slip?

No pressure registering on pressure gauge (new), though excellent pressure when pump is running. I have blowback and very small amount of water dripping from air relief valve and one spot under the band on the lower half of the filter tank. Grids look good, O-ring is good, replaced with magic lube. Dpn't understand why my pressure won't rise above 4 lbs. Filter is 13 years old. Pentair, Hayward, system w/ Variable Speed Pump.
